Hello All,

 

Anybody have any experience with either the HB-65 or HB-67 from the 1966 and
1967 ARRL handbooks? Inquiring minds, and all that (;->).

 

Cheers,

 

Brian

Funny that you ask....

I was thinking on posting pictures of my work in progress HB-65-50 (50th
aniversary). I started about 10 years  ago.
I decided to go with  two 6U8 as first and second mixers.
Since is fairly compact, the upper bands converter will go either on a
separate chassis or.... forgive me... solid state.
Give me a little time and I'll upload some pictures to my server.
So far I have the audio stages built.

Best 73,

Hugo - AA1XV

No experience, but -- this isn't going to surprise anyone -- an
opinion. As a way to use a mechanical filter that you have and want to
use this is good; otherwise it's a mixed bag.

The problem in HF receivers is NOT low noise or hearing weak signals.
At least up to 20M the problem is rejecting the vast amount of garbage
found in and near the ham bands. The mechanical filter solves part of
this problem -- near channel interference -- but unless used with a
great deal of selectivity ahead of the filter, it does not solve the
problem of images -- signals coming in on the other side of the LO
frequency. That's because the frequency is too low for a 1st IF.

A mechanical filter could work well at the start of a second IF,
following a 1st IF of 1.6 Mcs or more. However the design up to the
mechanical filter would have to keep signals small because these
filters don't handle large signals well.

One could adapt the W6TC designs to use a 455kcs 2nd IF instead of the
85 or 100 kcs frequencies that are standard. Then use a 455kcs
mechanical filter after the 2nd mixer. That way you've got those high
Q front end coils lopping off the image on the lower bands where it'll
be most troublesome.  

The HB-67 design (and relatives -- this design appeared at least
1965-69 in various flavors) could have been improved by the use of
very high Q front end coils a la W6TC, but since it's bandswitching
and predates the common use of toroids, not so.

I would probably also go with an RF stage run at close to unity gain
in order to simplify the coupling between the coils and allow AGC
ahead of the filter. The 6EH7 would be ideal for this. Of course that
does complicate the design.

For use right behind the 1st mixer CRYSTAL filters at higher
frequencies are an ideal choice. The Heath HR-10B filter -- two
1680kcs crystals in a half-lattice arrangement -- is simple and works
well.

These filters don't handle super-large signals either -- the crystals
can fracture, as found in some of the HR-10s out there, probably due
to the owner transmitting with the antenna still hooked to the
receiver. But as far as normal signals are concerned they're good and
being located at the 1st mixer makes it easier to keep signal
amplitudes down. Up to the point of fracture I don't think non-linear
effects are a problem.

In fact, crystal filters and 'mechanical' filters are both mechanical
filters. The ones called 'mechanical' couple electrical signals to
mechanical resonators by magnetostriction while the crystal filters do
it via the piezoelectric effect, but in both cases you're using
mechanical vibration of a solid as a tuned circuit analog.

An additional minor issue with the HB-67 design is that it 'uses' a
beam deflection mixer basically as a high gain pentode mixer. To get
the advantage of balanced mixing (so that the input signal is
canceled at the output) it would need a balanced output circuit,
meaning some sort of coupling transformer ahead of the mechanical
filter -- or a filter specifically designed for balanced input.

Hello Walt,

~ No experience, but -- this isn't going to surprise anyone -- an opinion. 

Well Walt, I for one really value your opinions!

~ As a way to use a mechanical filter that you have and want to use this is
good; otherwise it's a mixed bag.

Carl, KM1H says that selectivity gotten with tuned circuits sounds better
than with crystal filtering. Could this be because of the incredibly high Q
of crystals? Are mechanical filters prone to ringing as well? In any case,
my limited junque box doesn't contain one.

~ The problem in HF receivers is NOT low noise or hearing weak signals.
At least up to 20M the problem is rejecting the vast amount of garbage found
in and near the ham bands. The mechanical filter solves part of this problem
-- near channel interference -- but unless used with a great deal of
selectivity ahead of the filter, it does not solve the problem of images --
signals coming in on the other side of the LO frequency. That's because the
frequency is too low for a 1st IF.

The first IF on the HB-65 is at 1700 kHz, and the second is at 100 kHz.
Since it's a "band imaging" 80/40m receiver, it's not really a bandswitching
one, unless you count the switching of crystals in the converter section as
bandwsitching.

Of course, when you use the crystal controlled converter for the higher
bands, you have a triple conversion receiver. And switch on the BFO, and you
have four (count 'em) oscillators running all at the same time---a full
blown aviary!

~ That way you've got those high Q front end coils lopping off the image on
the lower bands where it'll be most troublesome.  

~ The HB-67 design (and relatives -- this design appeared at least
1965-69 in various flavors) could have been improved by the use of very high
Q front end coils a la W6TC, but since it's bandswitching and predates the
common use of toroids, not so.

So are you saying that toroidal coils in the front end can be made higher Q
than air core? That's really interesting, if that's what you mean.

The 7360's ability to handle strong adjacent channel signals is one of the
most attractive aspects of the HB designs.

~ I would probably also go with an RF stage run at close to unity gain in
order to simplify the coupling between the coils and allow AGC ahead of the
filter. The 6EH7 would be ideal for this. Of course that does complicate the
design.

Thanks very much for all your comments!

Cheers,

Brian

Just found out what was causing the problem with my Master CD and why I could not make copies. The first CDs I made available (including my Master) were provided with a really neat multicolor CD artwork label from Avery. That was the problem .....after 5+ years the CD starts out flat but when slightly heated in the CD drive, it becomes curved like a lens. This is apparently due to the label shrinking properties. After it sits overnight it's flat again. So if you are having problems reading one of the older CDs with a complete circular label, take it off with some Goo-Gone and it will remain flat. I see Avery no longer offers those CD labels. 73 Kees K5BCQ.

Hi,
Here's some information about another problem with home burned CD's.  The
following is a copy on a letter informing a photographer friend of the
situation.
73
Bill W3KOC

Hi Rachel,

 I?ve enclosed an article for your information.  It?s concerning the shelf
life of burned CD?s.  Even though I have had some problems with music CD?s
I was unaware that home burned CD?s (and DVD?s) were not a permanent
storage medium.  Naturally, I?m concerned that you might have unhappy
customers who, after a time, find that their pictures are no longer
retrievable.



Believe it or not, this information is difficult to come by.  It all
started when Nancy heard at a Mac class that stick-on labels are a no-no.
Naturally, I was skeptical. Thus the investigation.



The plot even gets thicker.  There are different grades of CD?s.  I was
under the impression that the only difference would be in the degree of
quality control.  Not so.  It seems that there are various materials used
as the receptor for the burning process and some are more permanent than
others.



I guess Rachel, the bottom line is to be aware of the limitations of the
process and (if necessary) have a back-up system.

For what it's worth. 

About 10 years ago my late father burned DVDs of about 100 hours of home movies and gave a set to each of his children. They have labels printed onto them -- I am not sure how he did this. They don't look like "stick-on" labels, it's almost like he actually ran the DVDs through his printer.

Ten years later, these DVDs are essentially useless -- I cannot get them to play back on any device, whether a PC or a dedicated player. However, my dad was prescient in that he also gave me a copy of all of those DVDs on a portable hard disk, and those copies are fine (and I have since made copies of the copies, onto yet another hard disk).

I have no idea whether the labels are the issue. Right from the beginning, these DVDs were "flakey" -- they would work on some DVD players, but not others. Even DVD players that were advertised as able to play back "home-burned" DVDs wouldn't necessarily play back these disks.

After more than two decades' worth of experience with burnable CDs and then burnable DVDs, I must say that I don?t trust them. For our business data we use multiply redundant hard disks, and for archival storage we used, for a long time, magneto-optical (MO) disks -- I have about 300 of those and only one of them has ever failed, but nowadays it looks like they are only used by the medical data industry.

Nowadays I consider home-burnable CD/DVD media to be "ephemeral" storage. This does *not* apply to commercially produced audio CDs and DVDs: I have never had a failure with those, unless they were defective right from the word go (very rare, but it happens; I have a couple of commercial audio CDs that "skip").

Hi,

CD's & DVD's have an organic compound coating. They start to deteriorate 
the minute they roll off the production line.
There are various coatings (and accordingly prices) in use, the 'best' 
is the gold coating which has a supposedly guaranteed life of 10 years.
The other coatings (silver, blue, green etc) have various lifespans but 
of course that is all subject to things like storage, humidity, exposure 
to sunlight or UV (fluorescent light) etc.

CD & DVD media is definitely NOT for long term storage. At this stage 
the ubiquitous USB disk drive is still your best bet as long as you 
treat it with care, i.e. do not bump, drop or rough handle it.

Kees - thanks for the note on the labels, I should check my CD but the 
first thing I normally do is copy everything off to hard drive as a backup.

Do you know which Handbook has the last version of the HB-67? I would like

Thanks Ian,

I have the 1966 handbook, and have just ordered '67, '68, and '69 from ebay
and Amazon used books, so I will soon know for sure. Typical price on these
is $5 plus $4 shipping for one in good to very good condition---a bargain!

Subject: [HBR] HB-67's last Handbook appearance?
Message-ID: <5bf829d0.119241.14ac55747ab.Webtop.48@charter.net>

I know not on topic,
but I just bought three myself.  They
came in the mail last Monday...
1956, 1963 and 1975.  Have a dozen
others somewheres : )  But think I will
get a few more throughout the next few
years.  Lot of fun paging through these
and day dreaming.  It's interesting to note
that the 1975 Handbook looks 20-30 years
older then the other two : )  Brownish paper.

PS still did not get my HBR CD, I'll check
the bank statment and see if the check had
been cancelled or not.

One of my great treasures is the 1945 Handbook that was given to me, by an 
Uncle in the Navy.  BEST are the adverts in the back - wish they'd never 
stopped doing that.  I also have a 1943 "Special Defense Edition" - it's as

Hello All,

 

In case you haven?t run across it, here is a source for a 6:1 planetary
reduction drive for ?? shafting---$10
I thought that these were long gone:

 

http://www.midnightscience.com/index.html

 

I queried them about backlash on the unit, and they responded that they had
sold several hundred without hearing of any.

 

This is the website of the Crystal Set Society, and they have a few other
items of possible interest to HBR builders. Click on ?Parts? at the top of
their home page.

 

Cheers,

 

Brian

Hi Brian,

I have an 80/75 meter transceiver made by Dentron that uses a pair of 
those reduction drives in series for 36:1 reduction - 18 turns from end 
to end of the tuning range. The first 6:1 unit will multiply any 
backlash in the second unit by 6 times and add it's own backlash to 
that. There is *NO* backlash in the radio I have. You should be happy 
with them. I also did not know they were available and I have bookmarked 
that web page. Thanks for sharing it.

73,

Bill  KU8H

Hi Brian,

Oren Elliot also makes reduction drives. 

http://www.orenelliottproducts.com/planetary-reduction-drives

I was going to suggest Jackson Bros drives but I think they have gone out of
business.

Another option is the Vernier capacitors - Some of the no-name vernier
capacitors are really stiff. 
I have a way to add a dial plate to the verniers capacitors using parts from
a shaft coupling.

Hope your receiver project is going well.

In case you haven?t run across it, here is a source for a 6:1 planetary
reduction drive for ?? shafting---$10?I thought that these were long gone:

 

http://www.midnightscience.com/index.html

 

I queried them about backlash on the unit, and they responded that they had
sold several hundred without hearing of any.

 

This is the website of the Crystal Set Society, and they have a few other
items of possible interest to HBR builders. Click on ?Parts? at the top of
their home page.

 

Cheers,

 

Brian

Hi Brian,

I have an 80/75 meter transceiver made by Dentron that uses a pair of those
reduction drives in series for 36:1 reduction - 18 turns from end to end of
the tuning range. The first 6:1 unit will multiply any backlash in the
second unit by 6 times and add it's own backlash to that. There is *NO*
backlash in the radio I have. You should be happy with them. I also did not
know they were available and I have bookmarked that web page. Thanks for
sharing it.

73,

Bill  KU8H

Good morning Don,

~ Oren Elliot also makes reduction drives. 

http://www.orenelliottproducts.com/planetary-reduction-drives

Thanks for the source! In all my searching around the web for the last two
or three years I haven't come across this one. It looks like they are the
manufacturer of the 6:1 drive that the Crystal Set Society sells, and
probably their capacitors as well. 

~ Another option is the Vernier capacitors - Some of the no-name vernier
capacitors are really stiff. 

~ I have a way to add a dial plate to the verniers capacitors using parts
from
a shaft coupling.

I'm always interested it mechanical ideas---do you have drawings or photos?
And, I'm not familiar with "vernier capacitors---whazzat?

~ Hope your receiver project is going well.

This pesky business of making a living---at age 75 no less!---keeps getting
in the way of my hobby (;->)...Fortunately, I enjoy my work. Now I just have
to see whether I can make any money making guitars. I did, very
un-expectedly, sell one just before Christmas, hence a small budget for ham
stuff appeared in my Christmas stocking. Got any HBR parts to sell?

Cheers,

Brian

I don't see prices for the reduction drives on the website. Anyone know
how much they retail for in the US?

Hello Ian,

IIRC The Crystal Set Society gets around $11 for the 6:1 reduction.

Cheers,

Brian

The original drives were made by JACKSON, and use a ball-bearing "gear" 
reduction - they have VERY LITTLE backlash... not sure about these.

Message-ID: <!&!AAAAAAAAAAAYAAAAAAAAAO9WiXwKTRJMveKqmcXf97/CgAAAEAAAAEvtT4pOieJKkqOtQaftfAYBAAAAAA==@lessonsinlutherie.com>

Hello All,

 

Thanks to the generosity of Larry Baker WB5OFD I'll be getting an HBR-8 by
UPS this afternoon. Larry describes it as " rather beat-up", and "It would
probably make a good parts rig for a new build from original parts." 

 

I'll have a good look at it to see if it's worth re-furbishing, or whether I
should start from scratch. In either case, I'm interested in knowing how to
keep the "birdies" in their cages. That might even be an appropriate
metaphor, as I suspect that one answer is shielding, though with a bit
tighter mesh than you find in a bird cage.

 

With the commercially made receivers that I have used, even single
conversion, the extraneous whistles on the higher bands due to local
oscillator harmonics have been quite annoying. So, any suggestions that you
might have for mechanical or electrical configurations to quiet our "fine
feathered friends" would be most appreciated.

 

Cheers,

 

Brian

Sometimes it can be very difficult to tell which signals are causing
the interference. High harmonics of the BFO can mix with lower
harmonics of some other oscillator, for example. You can sometimes
get a clue by observing how fast a birdie moves relative to the tuning
control - a fast-moving birdie indicates a multiple of your variable
oscillator is involved.

There are programs that will calculate mixing terms that fall within a
given window, but in a typical superhet there are too many such
windows, and the number of potential interferers is just too large
to manage (in my limited and frustrated experience, anyway!).

Hello Ian,

interference. High harmonics of the BFO can mix with lower harmonics of some
other oscillator, for example. You can sometimes get a clue by observing how
fast a birdie moves relative to the tuning control - a fast-moving birdie

limited and frustrated experience, anyway!).

Right, the little buggers multiply like rabbits! I figure that a combination
of shielding and by-passing would be the place to start. For the BFO and
second LO, that will hold still at least, might it be possible to use a
simple band-pass filter to at least quiet down their harmonics?

Pity the poor HB-XX guys with 4 oscillators running at the same time!

Cheers,

Brian

Hello Bill,

~ Thanks,

~ You keep reminding me why I like regens <evil grin>

That's what I like about them too, but I got almost no encouragement on the
regenrx list for making a viable "communications receiver" that was a regen.


And, I tried to whip up some enthusiasm for figuring out how the RAL did it,
remember?Even Mr. Regen himself---Dave Newkirk---said that you just have to
put up with the regen's poor strong adjacent channel signal handling
performance.

Come up with a regen design with the selectivity and strong signal handling
ability of a superhet, and I'll build it. By the way, I think that can be
done, but it will have to be by somebody that knows what he's doing---that
leaves me out!

Cheers,

Brian

Hi Brian,

My post didn't really have anything to do with those threads over on 
regenrx. As for 'putting up' with the regen overloading on strong 
signals that is really just part operating the radio. You will have to 
operate your HBR, too. Just it's different from a regen. With the regen 
you have to personally manage the gain control and incoming signal levels.

Once upon a time "Amateur Radio Licensees" were also referred to as "ham 
radio *operators*". Radios had to be "operated", not just listened to. 
Some still do. Regens in particular still do. There are quite a few 
knobs on that HBR. You might not have to use them as much as you use the 
few on a regen but you will have *operate* that HBR, too. I recall 
offering you encouragement with your HBR after you decided to do that 
instead of a regen. I'm not trying to change your mind. It's all good.

So are you going to clean up the HBR-8 or strip it for parts? I will 
suggest that getting the HBR-8 running nicely could help you with 
experience when you build your new HBR-32 <evil grin>.

73,

Bill  KU8H

This takes me back to when I first got my license.  I'd moved away from my
brother, we were close, and our phone bills were climbing.  So, we studied
and decided to start off as general class.  For the code requirement, I
used SuperMorse (this was in the DOS days) to gradually go from slow to
fast, and I had it feeding from some text files of dirty jokes.  Anyway, we
succeeded and brought home a couple of Heathkits.  When we got home and I
actually sat down to look at the HW-101, the knobs were very, very
intimidating.  Studying for the tests hadn't prepared me.  As far as life
experience goes, all I'd done was tune a stereo to frequency, adjust
volume, and maybe play with tone.  In my mind at the time, several of those
knobs just had to be superflous.  Each one makes a huge difference,
however.

Same's true with the other rigs.  I hope to get an HBR-8 together, but I
want to get back on the air, first.

Regards,
Stan

I guess that is way so many old HB rigs did not have markings or labels?

Hello Bill,

 

~ My post didn't really have anything to do with those threads over on
regenrx. As for 'putting up' with the regen overloading on strong signals
that is really just part operating the radio. You will have to operate your
HBR, too. Just it's different from a regen. With the regen you have to
personally manage the gain control and incoming signal levels.

 

~ Once upon a time "Amateur Radio Licensees" were also referred to as "ham
radio *operators*". Radios had to be "operated", not just listened to. 

Some still do. Regens in particular still do. There are quite a few knobs on
that HBR. You might not have to use them as much as you use the few on a
regen but you will have *operate* that HBR, too. 

 

~ I recall offering you encouragement with your HBR after you decided to do
that instead of a regen. I'm not trying to change your mind. It's all good.

 

I'm sorry if I sounded a little testy in my email. I was kinda disappointed
in the lack of response from the guys on regenerx. My very first radio was a
Knight Ocean Hopper, and I have a soft place in my heart (head?) for regens.
I was hoping that some clever fellow over there would come up with a design
for a regen that would perform well enough to be enjoyable to use on the
air. 

 

I was licensed once upon a time, back in 1953. The receivers I had then
didn't have many knobs to use, and no options when a strong signal came on.
You just turned down the RF gain, and the guy that you were having a QSO
with disappeared. I'm looking forward to having a bunch of knobs to twist!

 

I had a borrowed ARC-5 for 40 meters, and then managed to save my lunch
money and coke and beer bottle deposits to get together the $35 for an
S-20R. Selectivity was just not part of the deal with either of those. Half
a dozen CW signals audible all at the same time was not unusual.

 

I got pretty good at using the selectivity between my ears, but I was an
energetic teenager then. Now I'm 75, and am looking for the comfort of being
able to listen just to the guy I'm rag-chewing with. Since I'm now in W6
land, with "California Kilowatts" and antennas by Eimac, the strong signal
problem is rather more severe than in South Texas in the fifties.

 

~ So are you going to clean up the HBR-8 or strip it for parts? I will
suggest that getting the HBR-8 running nicely could help you with experience
when you build your new HBR-32 <evil grin>.

 

As of this moment it hasn't arrived, so I haven't laid eyes on it yet---it's
supposed to be here late this afternoon. I have a real aversion to carving
up a radio that could be restored. I have a Viking II that I got for parts,
and I can't bring myself to do anything to it but clean it up. 

 

So, if the HBR-8 looks like the builder was trying to do a good job, I'll
probably just try to get it working. I'm putting together a test bench with
some test gear. I worked as a tech at Stanford labs and HP in the late
1950's, so I do have some trouble shooting experience stored way back in the
dark recesses of my mind (;->).

 

Cheers,

 

Brian

Keith. 

I too think it's doable, but with limited time and money, I'm just trying to
come up with a radio that I will actually use. Also I have a penchant for
carefully planning how I'm going to carefully plan a project (;->)... 

Are you working on an HBR? I may have some parts for swapping.

Greetings Folks
   Just a quick question
Anyone know of Jay?s welfare?  I sent off for
that CD 11/20/14 and giving time for Mr. Postman
it should have gotten there by now.  Did not hear from
Jay, and heard from another list member they did not
get their disk either.  I have lots more time then monies,
and am not too hurried, but after this amount of time,
thought we might ask for a health and welfare check.
I?ve been told he was very much on the ball, and would
notify us right away when he got the check, and with
electronic money transferring no a days, he should have
gotten the money by now.
   Anyone know Jay and can ask him if he even got the
check or not?  I?ve asked a question a while back, but 
did not get an answer, it was about a different source for 
the HBR series, and thought he might know what I was 
asking about.
   Guess I would like to ask someone for a copy, and when
Jay accepts the info, would be happy to pay.  Either him 
or you?  Perhaps the check got lost in the mails???   I did
look at a couple of check stubs (carbon copies) but did not
see his check, but then again we have 4 checking accounts : )

Hi Bill,
 I recently learned that, at least under extraordinary conditions, regens actually can have birdie problems. I was using a hb regen, while listening to 160m. I was hearing legit 160m signals well enough, but I was puzzled by the fact that I was also hearing numerous CW signals below 1800 Khz.
 I discovered that the 2nd harmonic of the oscillating regen detector, was beating against incoming 80m signals, to yield audio output.
 This problem was greatly exacerbated by the fact that I was using an 80m dipole, as a receive antenna.
 As a result, the ~ 3.5 Mhz signals, that were delivered to the receiver, were actually much stronger than the desired ~ 1.75 Mhz signals.
 I made certain to use the 160m antenna, for receive, as well as xmit purposes, after that experience!

Hi Ron,

Did that regen have an rf amp and the associated tuned circuits? A regen 
doesn't need an rf amp for signal gain as the detector has plenty. An rf 
amp isolates the detector from the antenna and helps with rejection of 
signal 'far' removed from the operating frequency. My regens have the rf 
amp and the tuning is tracked with the oscillating detector. There is a 
gain control on the rf amp that really acts more as a variable 
attenuator. Some fellows add a potetntiometer in series with the antenna 
to reduce the input signals but that does nothing to filter signals 
outside the band of interest.

Hi Bill,
 My 24A/27/27 regen does not have an RF stage. Many of the "old time" regen circuits, that I have seen, used untuned RF stages, and thus would have shared this particular "birdie" response issue.
 I don't remember for certain (that happens a lot these days!), but I may have had the regen control advanced beyond the most sensitive position (at the very threshold of oscillation), at the time that I observed this phenomena. I suspect that this would increase the magnitude of this "birdie" response, due to an increase of harmonic energy output, from the oscillating detector.
 Anyway, I just wanted to pass along what I believed to be a rather interesting and perhaps unusual problem.

SSB. The narrower passband near that critical sweet spot is more 
desirable. I have started on a SimpleX Super, a variation on a 
supergainer - superhet with a regen detctor. After that one I want to 
revisit the 6SN7 regen from the old handbooks - the one I build in my 
early teens. I would like to do a better job of it this time. There is 
no rf amp and I don't intend to add one. I'll keep this in mind and see

Hi Ron, Bill and the group.

In 1955, as a 17 year old, I also built  the 6SN7 regen from the handbook.
It was not a success story. I heard little on it, mainly due to a power full
BC station nearby.  Forty years later I again built the same regen, from the
same handbook. This time it worked better, but not spectacular. Since then I
have gone on to built two ZL2JJ receivers and the 6SN7 rig sits on the
shelf, along with the slat board 6L6  as a reminder of years gone by.
This has nothing to do with birdies, just a story that came to mind when I
read Bill's posting.

I talked with Jay and he is tired but about mended.  He apologizes for being out of touch and in the delay of filling orders.
 
A few days ago, he fulfilled the orders for his eBook "Recollections. . ."  
he accumulated while recuperating.  So if you've ordered a book from  him and you don't received it by the end next week, give me your  information (name, call, address and about when you placed your order) and I'll  get the information to him.

Greetings Folks
Just a quick question
Anyone  know of Jay?s welfare?  I sent off for
that CD 11/20/14 and giving  time for Mr. Postman
it should have gotten there by now.  Did not hear  from
Jay, and heard from another list member they did not
get their disk  either.  I have lots more time then monies,
and am not too hurried,  but after this amount of time,
thought we might ask for a health and  welfare check.
I?ve been told he was very much on the ball, and  would
notify us right away when he got the check, and with
electronic  money transferring no a days, he should have
gotten the money by  now.
Anyone know Jay and can ask him if he even got  the
check or not?  I?ve asked a question a while back, but 
did not  get an answer, it was about a different source for 
the HBR series, and  thought he might know what I was 
asking about.
Guess I  would like to ask someone for a copy, and when
Jay accepts the info, would  be happy to pay.  Either him 
or you?  Perhaps the check got lost  in the mails???   I did
look at a couple of check stubs (carbon  copies) but did not
see his check, but then again we have 4 checking  accounts : )

FB Lee.  Yes, my CD arrived today! Hooray! :^))

A big public Thank You to Jay, I personally wish him a continued recovery and good health. I have much to learn from those that came before me. Thank you.

All my very best,

73, Mike WH6YH

Hi,Has anyone got any experience of using a wavechange switch or reed relays in place of plug in coils?I was going to use reed relays, any advice?

The central concept of the W6TC receivers is using LARGE coils
designed for high Q in a manner that gives leads short enough for good
stability.  In the 1950-60 time frame that could only be done using
plug in coils.

With just one coil set in the receiver at a time those coils could be
located close to everything. That's the key to the ability of these
receivers to outperform virtually everything else in the ham market at
the time.

Shrinking the coils to keep short leads when using a bandswitch cut
the Q by maybe a factor of four; keeping the big coils when using a
bandswitch meant long leads -- stray couplings and VHF oscillation
problems. You can test almost any commercial receiver of the period
and see how 'small coils' worked out.

Now there are other ways to go. Replacing the big solenoid coils with
medium-size toroids (RF and mixer stages) and smaller coil forms for
the oscillator will work fine and would allow your choice of
bandswitch techniques. It's still not a trivial exercise -- you have
to find room for the trimmers, oscillator stability will be tough with
poorer cooling of the oscillator coils, and optimizing the layout is a
chore -- but it IS doable.

I don't know that there's any particular reason to prefer one kind of
switching over another. Reed relays certainly give you layout
flexibility.

This may be a little off subject.

I have been trying to make contact with Kees Talon, K5BCQ. I want to order
one of the kits he offers.

I have unsuccessfully tried several different email addresses , including
the ones shown on his website.

Anyone else had better luck than I?
