I am fixing an old radio for a friend of mine.  It is a Firestone Air Chief
S-7398-8

Picture found on the internet here
http://radioattic.com/item_sold.php?radio=0002474X

Replaced the 5Y3 rectifier and repaired the speaker.  Believe it or not, the
flexible wire from the cone connection of the voice coil was open.  Only the
string was left in the middle.  I was able to tack a piece of solder wick to
the top side of the voice coil wire and made a small hole in the cone then
soldered the other end to the frame terminal.  I then glued the small hole
on the cone.  I was afraid that something in the output XFMR or the hum
bucker in the magnet assemble would be shorted that would have caused this
but all check OK.   

The radio appears to be working now but there is a 4 pin connector on the
chassis which I have determined to be for an antenna coil assembly
connection.  I believe there is supposed to be some type of wave magnet
wound on the missing back.  It is probably a multi tap or multi winding
assembly with 4 wires that plug into the radio chassis.  I do not know the
specifications on this assembly as to whether it is part of some resonated
RF circuit or just a loop or a few loops.

Any info on the antenna coil assembles or schematic would be appreciated.
Maybe I can manufacture something.

Hi John,
  Take a look at the schematic that is found here:
http://www.nostalgiaair.org/PagesByModel/312/M0006312.pdf
  It looks like it was just two loop antennas on the back cover. But, the
schematic does show that there is a connection for an external antenna that
can be used instead. Antique Electronic Supply has a couple of replacement
loop styles that might work if you have the room on the back.

Thanks Bill I really appreciate the help.

You may be right but it appears to me that the two loops are part of the RF
front end and are resonated on two bands.  Looks like I may need to do some
experimenting unless someone has one and wants to count the turns for me

Something that would work better than solder wick would be a  strand taken 
from a piece of copper wire rope.

I don't recall where I found it, but I have a piece a few feet long, 3/16" 
diameter.  It is made like aircraft cable but the metal is pure copper.  It 
is about as flexible as a piece of cotton rope.  It has 7 strands just like 
tower guy wire, but each strand is made up of dozens of extremely small 
gauge copper wires bundled together.

My large antenna changeover relay, which I acquired n.o.s. but was built in 
the mid-1930's according to an ad I saw in QST or RADIO, was in use for only 
a couple of months before the flexible wire lead attached to one of the 
moveable contacts broke.  I fixed it, using several strands taken from that 
wire rope and paralleled together.  Within a couple of weeks, the one on the 
other contact broke in a similar manner. Metal fatigue.

The wire rope repair has been in use for over 4 years now and is still 
intact.  I don't have a clue what that copper rope might have been used for 
originally, but it's worth its weight in gold for making flexible wire 
leads.

The copper wire in the speaker probably just wore in two from metal fatigue, 
like the supposedly flexible leads to my relay contacts.  The relay wire was 
nothing more than ordinary stranded copper wire.  No telling how many of 
those otherwise excellent changeover relays were tossed out because of that 
problem, which was due to poor design of the flexible leads to the contacts.

Cool!  I took a look at the project page on your site.  I thought it was the
amp that used that goofy conduction cooled final.  That's a neat idea to mod
it, to eliminate the need for the 8873.  What you going to use the amp for
Steve?

If it turns out to be stable and reliable, I believe it will become the 
first linear amp to ever stay-put on my operating desk.  It should be 
handy for both AM and SSB.  The other desktop amps I've played with 
didn't impress me enough to be kept on the desk - they move to the 
shelf the same day.

Once it is working OK 80-10m, I'll see if I can add 160m.  The Russian 
tube should be a good conversation topic.

Ah-ha... it looks like I can adapt one of the inexpensive 1.75" (45mm) 
square panels meters into the SB-230 very nicely.  But I don't have any 
more of them.  Anyone have a 1 ma FS meter of this type?  They were

I suspect they are still made new as well... but don't see a source

If it turns out to be stable and reliable, I believe it will become the

handy for both AM and SSB.  The other desktop amps I've played with
didn't impress me enough to be kept on the desk - they move to the
shelf the same day.


Once it is working OK 80-10m, I'll see if I can add 160m.  The Russian
tube should be a good conversation topic.

CalRad still sell them.

Ocean State electronics did stock them. CalRad has many local distributors.
Check the CalRad site.

Bob - thank you for the tip on Calrad.   I ordered a couple meters from 
"Electronic Parts Direct" whoever they are.  Better price than Ocean 
State Electronics, and hopefully faster at getting orders out than OSE.

Thank you very much - great info.  Now that the SB-230 meter crisis is 
resolved, maybe I can go take a nap.  -grin-

I just acquired a RME 69 with matching speaker..Several questions:

1.How do I get at the power supply filters in the enclosed can..Looks like quite a job?

2.What is the function of the pull switch on the volume control.

3.I have the downloaded service manual but can't find the operator's manual..

Thanks...

I once was told that RME did not write an instruction manual for the RME69
and that the front panel was not labeled. At that time, the owner was expected
to know how to operate a radio. I dont have a manual but my RME69 front panel
has no labels.

The capacitors in the "can" were not designed to be replaced. The can and its
contents were replaced as a unit. Some have been able to "can opener" the can
and replace the capacitor with a modern capacitor. One should take care with
the chemicals inside the can. Others on the list may have a better  
description.

Good Luck,

Wonder if that can cap is oil filled?  If so, it will not need 
replacement unless it leaked.  Some older radios had oil filled caps 
in the round style can that looks like paper caps of the 40s, 50s, 
etc..  Is this one of the older style?

Message-ID: <27292.38794.qm@web58703.mail.re1.yahoo.com>

I need a Simpson Model 29 (4 1/2") panel meter with a 1 ma dc?movement.
It is to replace a bad one used in an old Sylvania tube tester. I would swap the meter faces to keep the Sylvania one in the tester. I could use one with a lower value, say 50ua, by adding a shunt. Not sure what?I could do with one?that had?a 100ma or 1 amp FS value; are these something like 50 ua movements with shunt built in?
Thanx, Jack

I was not able to get on last night or I would have jumped in to be NC.

I have never understood why, when a NC does not show up, all the guys on 
the freq sit around and wonder where the NC is, just jump in and be the 
NC. It's not hard!

You are right Dave... It was just a shock not to hear Jim...In all my years
either he or Brian are there...
I could have and should have jumped in...I heard from Jim and he said to do
it in the future if ne is not there... Very unusual...

I was not able to get on last night or I would have jumped in to be NC.

I have never understood why, when a NC does not show up, all the guys on 
the freq sit around and wonder where the NC is, just jump in and be the 
NC. It's not hard!

well that explains what happened, I had the 75A4 and KWS1 fired up for about 
an hour waiting and heard nothing, guess I was one of the many just sitting

After much work rebulding a junker SB-230, I finally noticed that the 
meter was blowed-up real good.   Anyone have a spare meter for a 
Heathkit SB-230 amp?

Message-ID: <489CE001.1060003@neandertech.com>

Hello all,

I'm working on putting an AM station together for a friend, consisting 
of a Viking II and NC-156, both quite cosmetically-challenged, but 
complete.

I did a bunch of work to bring them back to operation, including 
significant audio improvements in the Viking.

However, the IF in the NC-156 is 1500 KHz, and as you might expect there 
is bleed-through of broadcast stations on or near that frequency, 
especially on the 160M band, and especially at night, when there is 
sky-wave propagation there. The undesired signals are so strong that it 
makes operation on 160M totally impossible.

I first tried a series-resonant circuit from ANT to GND, and it was 
totally ineffective, probably because the source impedance of the 
antenna is low. Then I reconfigured my L and C as a parallel resonant 
circuit in series with the ANT at the receiver, and I was able to 
totally eliminate the 1500 KHz +/- interference. But, 160M signals are 
highly attenuated also (although S/N, if you will, where N is the the 
1500 KHz interference, is much better). Also WBZ on 1.3 MHz is very 
noticibly attenuated.

My trap consists of a 140pf air trimmer at ~40% mesh (= ~56 pF) in 
parallel with 200?H. I'm thinking a higher Q circuit (more C and less L) 
will sharpen the peak and I'll have less attenuation 300 KHz away from 
the resonant frequency of the trap.

Or is there a better way to eliminate the 1500 KHz QRM?

73 es Tnx,

Hi Larry
	You are correct in the thinking of a higher Q (more C less L)
however it is very important the lower L factor be made of larger wire with
proper spacing (a high Q type coil).  There are special dimensions and wire
spacing to be considered for a high "Q" coil assemblies.  I won't go into
that here as there are probably more expert coil winders available here on
the list than I am.  But I do know that it makes a difference.  The whole
thing will need to be put in a shielded box else coil assembly may act as an
antenna for the 1500KHZ

As I recall, 100pf and 100uh resonates at around 1590KC but you may want
higher C yet?

Another thing to consider:
You might use an antenna tuner but not the pi-net type with the series coil
as these are low pass circuits.  Instead the seldom seen pi-net with two
coils to ground and a series capacitor making a hi-pass network would be
real good but doing two adjustable coils would be a pain. So the old
fashioned link coupled parallel tank is best for this application.  Perhaps
some of the modern "T" nets might be good also I don't know.  

Perhaps the trap and a tuner together would work well.
Good Luck

Gents:

I just called on my favorite filter design program Elsie
and came to the conclusion that going clear down to
about 3 uH (resonated with 3000 pF) would be
advisable in a 50 ohm system.  The two items would
be connected in parallel to form a trap, and that trap
would be placed in series with the receiver antenna
input.

To do that would require a variable inductor and a
fixed capacitor, preferably mica.

With inductor Q value of 200 and capacitor Q of
1500  the loss at 1800 kHz would be about 9
dB and the depth of the notch would be about 40 
dB.

These comments are in rather exact agreement with
others so far.

Thanks to all that responded, still digesting the all the great 
information.

Not much radio time left to play this weekend, but will try to play with 
it some more during the week after work, and when I get something 
working to my satisfaction, I'll report back.

Much appreciated.

Hi All
?
I'm in the process of ham banding a 707 with some ideas from George W8QBG and some others like Jack AD5VO who use to work for Bauer, Gates, and Collins. What I have run into is that?one of the broadcast stations that owned this box (S/N 164 originally on 1190 probably in PA.?and moved to 1150 when it came down here to Dallas) pretty well savaged the power change (250 W / 1000 W.) circuitry,?and there?are no pictures of the right side panel?(from the back) circuit boards in the manual. 
?
Paul Gregg of Bauer?was sending me a packet of material containing documentation not in the normal operating / service?manual?that has been lost thanks the United States Postal Service, so I'm kind of up against the wall. The fiber boards do have some part numbers still printed on them her and there, but others have become unreadable over the years.
?
Would it be possible for one of you guys with a 707 to e-mail me a couple of photos of the side panel circuit boards so I can kind of put stuff back where it belongs? Hopefully Fritz Bauer won't roll over too forcibly with what I'm doing for inter-stage coupling and the PI-EL (thank you Mr. Tonne) output network.
?
If anyone needs a copy of the manual, I will be happy to make one for them. I have the original Bauer version and a later Sparta version.

Many thanks!

Bill,

Here's hoping the lost documentation from Paul Gregg was not the original, last known copy.

Meantime, let me draw your attention to Paul VE7KHZ's website, where he has a number of photos posted. He may have more already on file somewhere that he can dash off to you.

The "garden hose" sequence is a classic.

Looking forward to hearing that rig.

Subject: [AMRadio] 1500 KHz trap for NC-156
Message-ID: <1218475663.v2.mailanyonewebmail-243661@fuse113>

Last night I had a chance to play some more with this.

Perusing the junquebox yielded a 3-section, 400pF/section broadcast band
air variable and a piece of air-wound coil stock about 2" diameter and
about 2.5" long, #16 tinned wire, with spacing between turns about equal
to the wire diameter. The coil looked about right for an 80M tank coil for
a single 807 or 6146, etc.

I wired them in parallel and put the parallel combination is series with
the antenna lead. MUCH better - I could still null out the 1500Kc
interference, but signals a few 100KHz from 1500Kc were much stronger
compare with the earlier network of 200?H in parallel with 56pF. The new
component values are 1000pF (measured) and 11.26?H (calculated), which
approximates a series reactance of 92 ohms inductive (ignoring the
capacitor's presence) at 1.2MHz and 88 ohms capacitive at 1.8 MHz
(ignoring the inductor's contribution). WBZ at 1.13MHz was, within my
ability to read the S-meter of questionable calibration and with QSB, 2
S-units down with the filter in, compared to what it is with the filter
shorted out. On the 80M band there is no noticeable attenuation from the
filter.

I can live with this; I'm calling it good and moving on.

Thanks to all the helpful suggestions and comments.

Larry:

Let me jump in on that trap thing for just a
moment.  

You are trying to reject what frequency / frequencies?

And you want to pass what frequency / frequencies?

Reading your last mail here leaves me confused as to
what you wanted to do.  I thought you wanted to
reject 1500 or so and still pass 160 meter band but
you just now mentioned 1100 and the 80 meter band.

Hi Jim,

Apologies if my post was confusing.

Yes, I'm attempting to reject 1500 KHz, which is the IF frequency.

The receiver covers 0.3 - 1.2 MHz, and 1.7 - 17 MHz, skipping a band
approximately centered about the IF frequency. Therefore, the ideal (and
impossible) filter would be a brick wall stopband from 1.2 - 1.7 MHz, with
zero attenuation outside of that range.

I mentioned 80M only to comment that I noticed no attenuation that far
removed from the filter center frequency.

Yes, I wanted minimal attenuation at 160M as well. There were no signals
on that band when I was playing with this last night around 7PM local time
to use for reference, which is why I didn't quote attenuation for 160M.
However I was hearing plenty of static crashes on 160M with and without
the filter. I imagine the attenuation on 160M will be somewhat similar to
what I saw at 1.13 MHZ, roughly 12 dB - nothing to write home about, and
hardly optimized, but good enough considering the time and effort I care
to invest in this particular project.

Good work Larry:
	I have just a quick suggestion and it may not be even noticeable. 
When tuning for the 1500KC null on the trap start tuning from the low end
(maximum capacitance) stop tuning when you get enough attenuation even if it
is not centered on 1500KC.  You may find that you can reach enough
attenuation of the unwanted 1500KC when the trap is actually resonating at a
much lower frequency.  This will bring the gain back up a little on the 160
meter band.
	It may not work but it won't take long to find out.

HI All

To you guys who have Bauer 707's,?I now have an official factory list of voltages and resistances from multiple test points in the 707. If?anyone who wants them will e-mail me directly I will?send them to you.?
?
Having said that, I thought some of you might be interested in a cover letter Paul Gregg sent me with some notes covering "707ology" not contained in the normal manual. I quote.
?
"We had a young engineer from Taiwan at the plant in San Carlos for about six weeks in the early 60's. He was on a training mission in the area and spent similar time at Eimac, Ampex, and Lenkurt - all nearby. While at Bauer he built and tested a 707 and did these measurements." (The ones I mentioned above b.g.)
?
"About a year after he had been at our plant and had returned to Taiwan we started getting inquires through the Chinese Purchasing Mission in Washington about the 707. We soon started shipping 10 to 25 kits a year to Taiwan as well as some assembled units and lots of spare parts. In 1972 we ran the largest production run of any transmitter we ever built - 65 at one time, 50 of which were assembled for Taiwan. The other 15 went into inventory or to AFRTS."
?
"Over the years we shipped 225 transmitters to Taiwan. During a visit there I learned that these transmitters were scattered around the country at missile sites - covering the radio dial - all with programming on them - their method of keeping signals from Communist China out. A 707 'jammer"."
?
Thought some of you might be interested. If not sorry for the use of the bandwidth.

Message-ID: <1218632723.v2.mailanyonewebmail-243661@fuse114>

Last night I used the NC-156 receiver, with its 1500 KHz IF, on the Gray
Hair Net on 1945 KHz. With the 1500 KHz filter (parallel-resonant 1000pF
and 11.25?H) in series with the antenna lead, the 1945 KHz AM signals
were strapping with only a very faint beat note which varied in pitch as I
tuned through them with the AM detector. With the filter shorted out, all
I heard was a cacophony of broadcast signals - I could no longer hear the
net!

I am happy...

Just a little tidbit of an interesting story, at least for me, HIHI

On a similar incident of BC interference:
Back when I was about 18 yrs old, I was experiencing AM radio interferences

the details here may be incorrect such as the exact stations involved.  As I
remember we had two radio stations that were very strong 740 and 790.  These
two stations could be heard simultaneously every 50 KC across the 80 meter
band.  The RCVR at the time was a S85.  When I tuned the stations in on the
BC band they did not appear to be so strong as to over load the front end of
the RCVR nor did adjusting the RF gain or antenna tune have any effect.  I
went up on the roof with a portable SW RCVR and as soon as I got near a guy
wire there was the trouble.  It turned out that the two stations were mixing
together in rusty connections of the guy wires and when I had put the
telescopic pole on top of the house and tied the last guy wire down I just
dropped the leftover 15 feet of guy wire down over the gable and let it
spiral down the edge of the house.  Once I picked up the left over guy wire
the problem disappeared.

Just a little tidbit of an interesting story, at least for me, HIHI

On a similar incident of BC interference:
Back when I was about 18 yrs old, I was experiencing AM radio interferences
from two stations at the same time.  Now this was a long time ago so some of
the details here may be incorrect such as the exact stations involved.  As I
remember we had two radio stations that were very strong 740 and 790.  These
two stations could be heard simultaneously every 50 KC across the 80 meter
band.  The RCVR at the time was a S85.  When I tuned the stations in on the

(copied to boatanchors)


Recently I got in a few Boatanchor Items - among them is this cute little 
Knight (Allied Radio) 50 Watt CW transmitter - 80-40-20-15-10 - single 807 
final.

   It is in pretty good cosmetic shape, copper chassis and case, a few very 
minor dings - panel is good, some screws missing here and there. Not a junker 
or a 'shed special'. The 5U4 was broken; I replaced it. The 6AG7 and 807 are 
as-received..

   It had several broken wires from the front panel switches to the chassis 
coils - whoever originally built it didn't leave much slack. Also the 
Grid/Plate switch was (I think) replaced, the plate wires were reversed. 
Probably all the work on the switch caused the broken wires - a couple of which 
were just not obvious...  anyway it's working now - I have a 40M rock in it and 
it tunes and loads, making about 35 watts at '200' on the (awful, undamped) 
Shurite meter.

   I have a classic J-38 key mounted on a small piece of masonite to throw in... 
it'll be just like Jr. High SChool in 1962...   ;}


  I have some digital pix I took that I can send if you wish - I have downloaded 
the two-page description and schematic from BAMA (as jpegs) and a printout of 
that will also be included.

   Asking somewhere in the $75 range: re-live your Novice years again, minus the 
zits and the orthodontia....

   Will pack obsessively and ship to the US ONLY.

   Paypal is preferred - or MO or cash or maybe personal check (with FBI/CIA/TSA 
full backround scan).  :)



   PLEASE REPLY DIRECTLY TO ME, not back to the whole list.

Here's everything you'd ever need to achieve AM Immortality - just 
program it to turn on the receiver once in a while, otherwise there 
should be enough capacity here to keep your AM station ole buzzarding 
long after your key has become silent ;-)

*http://tinyurl.com/5vccbf

Revox, Carousels, "random" programmer - looks like it's all there (even 
I think the Fidelpac cart machine that does the time)

Probably not many of these complete setups left, it'd be nice to see it 
restored just for fun.  Although it might be hard to find anyone who 
would admit to having worked on 'em!   Especially one old chief engineer 
who always pronounced it "aumanation" and got really scarce when it 
acted up.   An honest description at least "not for the weak of 
heart"...or back.

Ugh.....maintenance nightmare, migraine alert! Was just discussing
these beasts recently with a list member. Yes - they look much cooler
than they [reliably] worked!

Jack K9ACT actually built a nifty little loop system for calling CQ a
year or so back. Works pretty well. Don K4KYV followed suit sometime
after. That's as much automation as I'd ever want to have in my
station. And those rotary 8-Track-looking beasts are the reason. There
has to be some audio evidence out there of one going berserk on the
air. Makes HAL seem like a pre-schooler.

No sleep tonight, the carousel nightmare is sure to return. Thanks
Bob. Thanks a lot.

KOMA in Oklahoma City, a 50 KW R & R station used a Schaffer 
automation system in the 60s.  All the music was on 10" tapes run on 
Ampex playback machines.  The commercials were on carts like these 
and they used the Gates carousels.  They were a maintenance headache 
for sure.

When the engineer took down the main transmitter for maintenance he 
also had to do a lot of head and capstan cleaning.  They used a non 
audible tone to control everything and sometimes there would be a 
musical note that would last long enough to fire the next sequence 
leading to two sound tracks at the same time.  Even today with the 
compute control, I hear that happen.  It was mesmerizing to watch 
that thing in action.  Two complete systems, one for operation and 
one for back up.

Hay Jim those are known as SUB Audible tones...When I worked for MUZAK every
city had six SCULLY decks and a controller to run the music,,, It would
switch from deck to deck so that the same music would never be played in the
same sequence. All with sub audible tones. Was my job to change tapes one
day a week and clean and replace heads when needed until Sat came in around
1981.
Now even the SCA has gone away. I have one dealer that still uses SCA in Mo.

On the Schaffer system some were sub audible and some were in the 
high (read out of band) tones.  Most were sub audible though.

Yeah Bob thanks a lot!!! :-) I had to let the involuntary muscle spasms stop before I could type this e-mail.
But if you're interested, I know where some are.?When I went over to Paris (TX.) to salvage some parts from what was left of a Bauer 707 the local engineer had the gall to ask if I wanted some carousels that were sitting in the rack in the next room. I let him live since he's a nice guy.

Hi Jim,

Sounds like the standard setup back then, they must have bought head 
cleaner and Q-tips by the case!   Schaeffer was the leader in automation 
I think.  But didn't KOMA run all their music off  carts?   That would 
seem to make more sense for a Top 40 station.

Missing from this setup but pretty common also was the big vertical cart 
playback units - my Gates book references Criterion 80 and later 
models.  They held 55 NAB type carts and played 'em in sequence from top 
to bottom.  The "programmer" could be any human who was able to read a 
program log ;-)

All in all it was pretty neat stuff back in the day.  As long as you 
didn't have to fix it with the boss breathing down your neck!

73, Bob W9RAN

Maybe a bit off topic, but, in addition to the 25hz left channel tone 
don't forget that you could also use 25hz on the right channel, and 35 
hz tones on each channel.  Add up all the different combinations and you 
really have a lot of horsepower!  This was really a slick way to get far 
more control capabilities than just a single tone on a single channel.  
This scheme was carried over to the early days of satellite delivery and 
proved very successful there.  (That sort of thing is done with serial 
string commands now.)  Cart machines had primary, secondary, AND 
tertiary tones on a third playback head so they were never heard on 
playback unless they were recorded TOO HOT  then you'd hear crosstalk.  
Those were the days...of denatured alcohol, cotton balls and swabs,  
broken brake bands, worn out and misaligned tape heads...

No;  each jock cut his own tapes, including intros or exits (only).

>  That would

Added to the customized tapes (each guy had his own set)
each jock also had his own "personality" stuff, which was
on cart.

As I recall news was done typically by a different voice, as
was most of the spot load.

My automated CQ'er uses Sony MiniDisc.  It works MUCH better than tape.  I 
use an audible 1000~ tone for control.  The control tone runs on left 
channel and the audio runs on right channel.  Works FB, since my AM signal 
is monaural, only one channel needed, and the channel separation with the 
minidisc system seems absolute, with no detectible cross-talk.

Subject: [AMRadio] New England ARRL Convention in Boxboro, MA, and the ROWH
Message-ID: <48B1B29D.9050901@neandertech.com>

I just got home from The ARRL New England convention in Boxboro, MA, 
after riding down and back with my friend Steve, KS1F (formerly K1MV).

The flea market was small compared to what I remember, especially 
considering the perfect weather both days - not many sellers, and it 
didn't seem very much trading was taking place. I was able to find a 175 
KHz IF transformer (I've been looking for some for years), as well as 
several 262 KHz IF transformers, all NIB/NOS, and an xtal in a nice 
round ceramic holder for 3945, which is the frequency for the "Old 
Buzzard's Net - a daily AM net here in the Northeast. Also picked up a 
few assorted other parts, nothing nearly as exciting as the former and 
not worth listing here, but stuff that I will definitely use at some point.

I also enjoyed looking at the vendor's display of the latest and 
greatest contemporary radio toys, but don't have the spare cash right 
now to indulge in any of that!

I enjoyed seeing many of my friends, dinner with KS1F, WA1QIX, KA2QFX, 
W1IF, WA1SSJ, and a beer and an eyeball QSO with Pete, WA2CWA. This is 
my #1 reason for attending these things any more.

A highpoint was the midnight Royal Order of the Wouff Hong (ROWH) 
ceremony. If you ever get a chance to attend one of these, it's not to

a prominent role in the sacred proceedings, but I can tell you no more

We had hoped to meet up with Bruce, W1UJR, for the ROWH ceremony - he 
was passing through Boxboro on his way home from the AWA conference in 
Rochester. But he was running late, and only arrived after the ceremony 
was underway, so he resumed the long drive back to Woolich, ME. I found 
a message from him when we got back to the room shortly after 0100, so I 
called him then only to find he had come, and gone.

Great seeing see you and Steve at Boxboro and a bunch of other folks I've
talked with on the air. Great fun and laughs in the watering hole.
Attending the midnight Royal Order of the Wouff Hong ceremony was also a
highlight in my Boxboro attendance. Although the flea market area seemed
to be somewhat smaller in size then past years, from my side of the
table, there was a steady stream of buyers throughout the day. Many of
the conferences also seem to be well attended from what I was told or had
seen. All in all, a great two day activity and I even got free breakfast
on Sunday.

Great seeing and hanging with you, too, Pete.

I never see you at the NEARFEST. You should come in October. Still a 
great hamfest; you'd enjoy it.

Some of you may know Carl, W4RCW.  He has an extensive collection of gear, test equipment, 2 Gates BC TX's, WW II surplus, Hallicrafters, Hammurlund, along with antique Collins and more modern equipment.  He is a frequenter of 160, 75, and 40 meter AM.  His station was located in the basement of his home, all antennas are located a minimum of 100 ft away, and all feedlines except one ladder line were installed underground.

His house took a direct lightning hit to the roof, as witnessed by his neighbor and immediately burst into flame.  The brick home was a total loss.  He was at work, his wife at the beach with the grandkids.  His dog did not make it.  The house collapsed into the basement, and his years of horse trading, dealing, and restoring are now under rubble and water, not to mention his families personal collection of memorabilia. 

Hopefully he will be able to rebuild, and perhaps some of his gear is salvageable.  It will be a while before any assesment can be made.

What a tragic message............thankfully Carl and his wife were not 
injured.  Sad about the dog also.

Best of luck to Carl and hopefully he will be able to rebuild and 
salvage some or all of his fine gear.

Thanks for posting this.

Subject: [AMRadio] Update on W4RCW fire. Msg 1
Message-ID: <800011.83289.qm@web53205.mail.re2.yahoo.com>

Hello all,

Was over at Carl's QTH today helping sort out the mess.  Their family dog did not survive the fire.  The house is a one story with a walk out basement, main floor was leveled, and the majority of the floor fell into the basement.  Of course water damage to the surviving items in the basement is extensive.  heat and smoke did in most of the ham gear.  But quite a bit is salvageable with much effort.  Carl was trying to get one of those PODS delivered, but no luck today.  Alot of the items we got out of the basement we had to just leave covered up with tarps.  The afternoon rain was not a help.  Right now, most of the kitchen floor is being held up by one of his Gates BC TMTRS on one end and a smaller equipment rack on the other.  Many things under that section suffered heat and some water damage and are possibly repairable.  We covered what we could to keep out the rain, but much work is still required to salvage more.  Interesting that the sheetrock that
crumbled and  fell from the ceiling and made embankments on equipment, protected it from the heat, and some front panels were almost unscathed.  Other things suffered yellowing due to heat, and many things had their front panels melted.  A Drake TR6 was almost fine next to a melted IC751. 

Carl and his son are hoping to find his wifes jewelry tomorrow.  Carl had recently moved many of his families historical information down from his Mom's house.  She is in an assisted living facility.  He was going through pictures and records and categorizing it all.  The family Bible, going back generations was also amongst the records.  They were in the living room, and hope for them surviving in any manner is slim.

Still more to do to get the remainder of his gear out.  Getting that floor off the racks will be a problem.  most work will have to wait till the rain stops.

Here is an email I received today, I could not include the pics he sent, but the link at the bottom is the video from the TV news.  If I can get the pix in photobucket, I'll send that info.


Hi all,

Really a sad scene at Carl's former house.  Words and these photos can't bring the reality of
the scene to you.  It is something to behold when there looking at it. 

I hope Carl forgives me for sending this but hope that we can all take lessons about what lightning
can do.  There are all kinds  of trees around the house and the tower was not up at the time of the
storm here a couple of days ago. 

There is a news clip on this but I don't have it yet and was on Channel 4 news local here in NC/SC.
If I can find the link at the news station will post as is dramatic.

I have several boxes of ribbon cable assortment.  Some pulls from used
computers, some new that came with motherboard and were not needed.  Floppy
drive cables, IDE cables 40 wire and 80 wire, SCSI cables, ETC.  I have too
many and will never use them in my computer business besides I get more
every day along with power cables.  So, aside from separating the wires for
use as small hookup wire for projects or making loop antennas what else or
they good for.  Anybody need some or want to make an offer for them.  They
may all go to the trash soon.

Make suggestions for use here but if you want some call me.

Call for more details.

Use them for ground strap, or bury them (with insulation intact) as ground 
radials.

Use them as Faraday shields between low Z links. Strip the ends of all wires
on one end, tie all of the stripped ends together by placing one wire across
all stripped ends and solder them together. Ground the ends that are  
soldered together, use a short ground wire. ( do not use between links  
with HV on the
links-most PVC wont stand much voltage). Cut the ribbon to size with sharp
sizzor's, leave the insulation intact on the non stripped end.

Helps prevent "top side capacity coupling".

Probably not a new idea but makes fabricating the shield in receivers easy.

Thanks to all who replied and your suggestions were all good ones.  These
are short pieces anywhere from 1 ft to 4 ft in length so I think I will put
some aside and dispose of the rest, connectors and all.   

Thanks again.
