Couldn't dig up any APC caps (Murphy's Law - I know, darned good and well,

Now to dig up the caps for the Heathkit AT-1.  6L6's rule the world.

Too cool ... this is of course the ham spirit and technique of old

That midsize Radio Schlock magnet wire is *very* close to #26 -- 
0.0165 instead of 0.01594 and allowing for the enamel that must be 
well within the tolerance for wire manufacture.

'mmf' is correct for these radios; I am always suspicious that if one 
attempts to build/repair a 1960 +/- design in pf, the set might not 
work.

Yes, Boys & Girls...

I too, have long suspected that the interelectrode arrangement of the micro-micros, contained betwixt those hallowed sheets of wax and mica) are simply in interspacial conflict with the newer style picos which we find in all sorts of tantalum, ceramic, and other galactic materials... which clearly were never meant to be... Hey!  Ever hear Tom Corbett & the Space Cadets talk about "tantalum capacitors"......no!... Why, it would simply have to be a Sprague Atom or some other manner of "Condensor".    

Oh... and to plagerize a columnar title - in the "For What It's Worth Department".... I have an original roll of 60/40 solder, bought from Burstein-Applebee (B-A) in KC, back in about 1960... that I use on my HBR and other prizes... after all, we simply can't take any chances on these things, ya'know.

Message-ID: <002901c53794$0e7715a0$6c02a8c0@dailey>

Perusing the website again, I reminded myself (difficult when the hair turns grey) of a few things I'd like to share:

Wrinkle Black Paint:  Harley-Davidson dealers sell a SPLENDID variety of this stuff.. yes, because it says "H-D" on the can, it's pricey, but it's of a thick-film variety and works great.

Lubricating variable-capacitor shafts and similar:  "Cramolin"... this is a contact cleaner/enhancer that was developed for B-47's and B-52's, as they were at high altitudes (low humidity) all the time, and controls dried up - it's something akin to sewing-machine oil in consistancy and while DEoxit is better for cleaning, the Cramolin doesn't dry up, so works great on variable-cap shafts and inter-section contact brush pieces.  PS - don't use it on TRANSMITTING switches - the stuff conducts at powered RF.

Replacement Dial Face plastic for ACN dials and such:  I've found that the really thick plastic that comes on certain packaging for large printer-cartridges and such (you know, the stuff you almost can't cut, and drives you nuts), cut to size, makes terrific replacement for dial-face plastic that has yellowed or been scratched.  Personally, I LOVE yellowed plastic dials - it shows USAGE.

A pound of No. 26, eh?  Where were you a year ago?

Good News gang... I tweaked the freshly-constructed 80m L-1 up on my HBR-11,
and peaked the other two coils as well, plus the L-4A and L-4B (Neither the
doggone notes, NOR the QST articles say diddly about these coils!), and at
3502 kc, was producing a "READABLE" signal of good intelligibility at .045
uv. -   .1uv was essentially S9 copy.  Produced from a HP-606A... ran out of
pads, so that's as far down as I can accurately measure.

The begger tracks from 3499 at the bottom to 4031 at the top (lets me listen
to the MARS folks), and produces terrific copy, that my contemporary TS-430S
and IC-706 MKII/G can't even HEAR!

Now to repeak the 40m & 20m coil-sets... Wowzers!  I always liked the
critter, but it's even better now.

Anybody out there got a modulation xfmr. for a Viking II?

Hi Gang,

Well, after having a blast with the HBR-11 last night, on 80m cw (band WAS open), it got me to wondering... anybody ever put an HBR on 160m?  Realizing that it's the coil dimensions that are the limiting factor here, I just wondered if anybody had done the design-brain-damage before me?

I'm not sure the coil is the limiting factor. I suspect the tuning 
capacitor range would limit you to only a portion of the band.

Having the first IF so close in frequency is a problem as well as finding
winding room on a coil form. HOWEVER, those comments are not a result of
having actually tried it. Go for it ! and see for yourself. How about all
the WARC bands ?

Kees ...

is right, as usual.   The consequence is you get a lot of direct 
feedthrough at the IF -- 1665 kcs in mine, 1615 in the real HBRs I 
think?   That shows up mainly as a higher noise level.

The cure is a trap tuned to the IF in series with the antenna lead.   
Such a trap would probably improve performance on 80, as well.  
The ideal would be a low inductance-high capacitance trap, very 
high Q coil.  You might lose just a touch of sensitivity at the 
1800kcs end of the band, but that's not much of an issue.   Haven't 
done it yet, but one of these days ...

There's no problem covering the band with the same tuning cap, 
though, because although the frequency is halved, the band is only 
200 kcs wide instead of 500.   If your setup covers all of 80, it will 
also cover all of 160 with the right coils and fixed caps.

You weren't the only one listening on 80 last night with an HBR -- 
boy, it really was open, wasn't it?  I was listening to the EAs 
working each other in the DX window, about 5-6 GMT.  

These receivers aren't second rate to anything out there except in 
'menus' and suchlike.  Anything anyone else hears, I hear, and I'm 
listening with a 160M fullwave loop with the highest point at about 
20'.  

Okay, so the guys with the Sterba curtains and the five-element 
80M rotatable beams hear things I don't ...

*Next* winter I'm gonna be working people with HBR & HBT.   The 
TX is going slowly due to too much else to do and a lot of time-
consuming mechanical work for the plug-in-coil unit.  

Yes, 160 is practical with the HBR designs.   I did it on the 1MHBR 
and it works just fine.  You put the oscillator above the band, just 
as for 80 meters.  I found I had to pile up the turns to get enough of 
'em.  Unfortunately I can't give specifics because my set uses 
command set coil forms ~3/4" diameter.   

Someone, surely, has the data.

Hi all,  I am an HBR-16 owner and I'm pondering building my own HBR.  I acquired this one a couple years ago and its a nice performer and a real pleasure to listen to.   I don't know who built it, nor does the previous owner know.  

I've been noodling on building a later model ham receiver and I'm considering the HBR along with some others.  While I know its like asking whats the best car or the best color of something, is there a best HBR?

I see the HBR-16 and subsequent HBR-11 and HBR-13.  They all seem to be fine and just variations of a theme.   The HBR-11 looks interesting to me, late model, Ted Crosby thought it was equivalent to the 16.  I don't know how the 13 compares to either. 

Maysome someone with a 13 or 11 can comment on performance.

  Scott, I have built the HBR16 and HBR13 and I have a HBR 12 which was
built by persons unknown.
  I have spent more time aligning and adjusting  the HBR16 than the other
two. This may have some bearing on the performance of this unit. Of the
three receivers, I like the HBR16 best. This is just my opinion and is based
on personal preference and not laboratory tests.
  The 16 and the 13 have good Eddystone dials while the 12 uses a Jackson
bros type dial, so the tuning function should not enter into my evaluation.
  I generally use these rcvrs for cw, ssb and some short wave listening.
  I plan on doing a HBR 11 or 12  soon, but, only because I have the parts
and I have not done one yet.
  Building any of the HBR's in my opinion, is a satisfying and rewarding
experience. I know I thoroughly enjoyed it.

  I see the HBR-16 and subsequent HBR-11 and HBR-13.  They all seem to be
fine and just variations of a theme.   The HBR-11 looks interesting to me,
late model, Ted Crosby thought it was equivalent to the 16.  I don't know
how the 13 compares to either.

  Maysome someone with a 13 or 11 can comment on performance.

Scott,

I don't know about the rest of the versions, but my HBR-11 provides
"readable" cw signals at .045uv... my contemporary stuff can't do that...
closest thing to it for performance is an older HQ-129X Hammarlund.

Build it like the originals did.... get a big enough chassis... punch it out
for a '16, then build an 8 first, then an 11, then a 13, then finish with
all 16... sort of like the old Heathkit electronics courses... hi hi hi

My impression as a non-owning student is that they're all good if 
you apply the standards of the 1960's -- they'll drift considerably 
during warm-up, for example.

Generally I think the later designs should be somewhat better 
performers.  One exception is that using the sharp cut-off pentode 
half of a 6AZ8 as an RF amp in the later HBRs was a bad idea 
compared to the use of the 6BA6 remote cutoff tube in the earlier 
sets.  

One option might be the 'Deluxe HBR' featured in Bill Orr's *Radio 
Handbook*, 17th and 18th editions.   The thing's amazingly 
elaborate, with 'hang' AGC and a separate S-meter amplifier stage 
but you can reduce the 19-tube count considerably by substituting 
solid-state diodes.   And many of us wouldn't need the voltage 
regulator tube either -- most power lines today are reasonably 
stable.  The Q-multiplier is a nice feature but could be deferred.   
The 7360 product detector is excellent but at $40 I'd suggest 
substituting a 6ME8 or 6JH8 -- both cheap tubes; bias voltages 
might have to be adjusted.   

If you're willing to make circuit changes, then the RF and IF amp 
stages in any of these receivers should be replaced with 6EH7's -- 
unbeatable for their combination of linearity over a wide AVC range 
and high gain.  Both mixers can usefully be replaced with the 'large 
signal' dual triode circuit found in many publications -- 6ES8's are 
best but 6J6's work very well and are 7-pin.   This mixer will deliver 
both better signal handling ability and lower noise than a pentode 
circuit and is slightly simpler.

The separate BFO of the Deluxe HBR can be folded into the 7360 
(or other tube) product detector.   There's no reason I can think of  
for having separated it.   The 7360 tube data sheets have the circuit 
but it can be used with any of the sheet beam tubes.  

One man's opinions ... mileage varies.

The 6AZ8 pentode is referred to as a "semiremote cutoff pentode" in some of 
my books.

The trouble with the otherwise-excellent 6BA6 is noise. On 80 and 40 they're 
fine, usually, but on the higher bands they just hiss too much. 6EH7 is the 
best alternative I know of.

The 7360 is an excellent product detector.  Just keep it as far as  possible 
from power supply iron.  I learned more than I wanted to from this  project.  
After experimenting with everything from mu-metal to 1/4 inch  steel, I am 
convinced that it is pretty hard to shield magnetic fields.   Had to reorient the 
power transformer to get rid of the hum.  Now my old  BC-348 does real well!

Thanks Lorne for your information. That is exactly what I am looking for - opinions and perferences based on actual experiences.   What I'm looking to do is figure out the 'best one for me'.  I'm looking to build a nice CW receiver, then build up a matching homebrew transmitter.

I vaguely recall that there were some drilling templates available for one or more of the HBR radio's.  I'd have to look into this.  Unlike others who are mechanically adept and savy, I'm a mechanical struggle at best. Were (are) there templates available?

As someone who has built up many HBR's, do you have any advice to someone as myself who is looking to build one?

Scott,

I have an original copy of "HBR Notes", as sent to the original builder of
mine, by W6TC himself.  I'd be happy to send you a copy of them... they're
on legal-sized paper, and are typewritten, with hand-drawn diagrams, but
they'll save you lots of headaches.  Coil winding tips are on the website,
but I'd add my own personal tips - as in spite of the clarity of the
instructions, they're easily interpreted in MANY ways.  Finding the original
1 1/4" 5-pin forms may be difficult these days, but many of the fellas on
this reflector have made them from everything, including pill bottles, and
just about anything.

The APC caps for the coils are kind of tough to find as well, but surplus
gear that you'll discover at hamfests, contain them, and it's worth it to
get the RIGHT thing.

Good Luck

  Scott, a very handy source of information for anyone contemplating the
building of an HBR receiver is a copy of Kee's CD on the subject.
  There are circuit diagrams, tips, the origional QST articles, coil winding
data, etc etc.
  More information than you will ever need and it makes the project go that
much easier.

A note on APC-type caps...

Some are made with aluminum plates and some with brass plates. The brass 
plated ones are usually plated so they don't look like brass.

For most applications they are interchangeable. But the brass-plate ones are 
reputedly more stable for VFO/HFO applications.

With all due respect to W6TC's excellent designs, the HBRs do leave something 
to be desired in CW operation - IMHO:

As I see them, the HBRs were meant as general-purpose ham receivers, mostly 
for 'phone or noncritical CW use. And they do the job very well for the 
complexity and cost involved, and the parts available at the time. 

The problem was that getting really good CW selectivity from the 100 kc. IF 
would require a lot of IFTs, and then some sort of complex switching 
arrangement to widen things up for 'phone use.

In addition, AGC and an S meter are of limited use in CW operation. A really 
slow tuning rate and high stability are  much more desirable.

My low-cost solution, back in the 1970s, was to build a basic 80 meter 
CW-only receiver, then precede it by a crystal-controlled converter for the other 
bands. For selectivity I used a crystal filter using FT-241 xtals in the 470 kc. 
range. The filter uses triode phase splitters and APC trimmers, and 
resistance coupling. Adjustment is simple - the trimmers are adjusted for maximum 
rejection of the unwanted side of zero beat. The circuit appeared in QST around 
1960 - it was first done at 1690 kc, then adapted for ~455. Two stages gives a 
really nice CW filter characteristic. 

Since the VFO only covers one range, it can be made very stable and unit 
construction can be used. A "squashed" ARC-5 VFO can do the job very nicely, 
without a lot of metalwork.

Of course this is a completely different approach from the HBR, based on 
different tradeoffs. But for CW work, it's a real advantage to have that sharp 
filter!

One rx I built around some of these ideas is shown on the HBR website.

Point well taken.  As to the 6AZ8 actually being semi-remote cutoff 
instead of sharp cutoff, I have run into that before with the RCA RC-
30 handbook.  Plus there are a few typos in there.

I absolutely agree... matter-of-fact, that very admonition is in either
Ted's notes or in the original articles... also, the aluminum ones can grow
"tin pest"... tiny little "mountains" of aluminum oxide, that can eventually
touch each other, and short out the cap... happens a lot on older radios
that have sat out in a barn or basement.

The HBR-11 I have, was built by a guy when he was 16 (I've met him - quite a
story, how).  He maintains that his building ability and mechanical ability
were fairly sad, but that's what folks did in 1964, when they didn't have
much money.  (His solder-joints were horrible... I'm still fixing them, as I
find 'em)

I built a receiver out of the '59 Handbook, when I was 16...and while my
ability was ...ummm, okay... I didn't have the metal working tools that
would have made it much nicer, in my Dad's workshop.  Still - it came out
okay, and after getting the local TV repair guy to align it for me (signal
generator?  Oh yeah, that's what the RICH guys have, isn't it?), it worked
pretty darned well.  I'd kill to find that darned thing, but Mom (The Queen
of the garage-sale), sold it when I went into the Navy in 1961.

My only advice... use ALUMINUM chassis, front panels, and cabinets... STEEL
may be cheaper, but it sure ain't easier.

  Scott, if you are concerned about the complexity of the project why not
start with an HBR 8.
  It is the simplest form of  the HBR. After that has been mastered you can
add a few tubes and convert it to an HBR11, all as part of the same chassis.
Eventually you can go all the way to the HBR12. Any one of the three
receivers would give very credible performance, something I am sure you
would be proud of.
  Besides, anyone who has built a 1927 MOPA will have no trouble with an
HBR!
  I second the motion, stay away from steel. Stick to aluminuim. Much easier
to work with.

Scott,  since you already have the HBR-16,  try building a different set of
coils for it for one of the bands that you don't have now.  That will be a
project in itself and will enhance your radio and give you a taste of what's
involved before amassing all the components for a complete set.  I don't
doubt that you can acquire all the skill needed - we humans may be a diverse
group,  but when appropriately motivated any of us can execute a set of
instructions so detailed as those for the HBR series of radios.  It's mostly
a matter of how much of your time (and money) do you want to spend doing it.
I too would love to build an HBR from scratch but I'm pretty happy having
access to the ones that others built.  Getting all the parts according to
the original recipes is in itself a project;  making decisions about
modifying the design for other parts available is a more difficult task
requiring experience and or experimentation,  or a lot of reading of
articles from the tube era,  or getting opinions from a group like this one.
I like restoring old radios so the temptation to build from scratch takes a
back burner in my case to reviving the old ones,  including the HBR series.
Their longevity in the ham community literature makes them especially
intriguing,  Dan.

Last night I spent some time browsing Kees HBR CD. I bought one from him
last year in anticipation of building my own HBR.      

I enjoyed looking at all the HBR photo's.  I especially enjoyed seeing the
'new' HBRs that folks built.  Some of you guys are real mechanical
craftsman!

Boy I dunno if I have the skills to build an HBR 11 or 16.  I'm really torn
too because the HBR-16 that I own is a sweet sounding receiver on 80, 40, 20
meter cw and ssb.  I'd sure like to build a sweet sounding receiver too but
not sure I have the ability to build a  complicated radio.

Of you guys that built your own HBR, were any of you mildly experienced or
lightly experienced when starting out?  How did it go?

What about building something a lot simpler, first?   There are 
hundreds of published receiver designs, all the way from one-tube 
regens up; four or even three tubes will give you a darn good little 
superhet.   

(By using 'band imaging' a superhet can tune two bands without 
bandswitching, just by tuning the front end.  80 and 40 meters is 
the easiest because you can get both bands just by swinging the 
tuning cap.)   

>From layout through checkout, such projects take a fraction the 
time; you just do not run into the complexities with four tubes that 
exist with 16!  The late 50's through 60's *Handbooks* have a good 
selection, running from a one tube regen right on up.  

Looking just at the projects that succeeded, I started out with fairly 
simple sets in the 1990's -- four, five, six tube designs.   However 
even the failures improved my construction skills.   

The main thing I did wrong was to build original designs right from 
the start.  They were certainly educational but a lot of times it was 
'education' instead of 'a working receiver.'   Someone with the 
wisdom to copy an existing design would have done far better.

Lorne and others suggested that I back off the 16, 13, 11, and look at a simplier radio to start with.  Lorne suggested the HBR 8.  I am intrigued with his comment about 'credible performance' with the HBR-8. Plus upgradeability.  I will look at the HBR-8 schematic tonight and see what it looks like. 

Baby steps are good. I still want to select the first receiver carefully so I end up with a nice receiver that is fun to use on 80, 40, 20 cw.  

I looked on Kees HBR site and only saw 1 HBR-8 mentioned, Darrells two HBR-8 photo's.  I haven't found Darrells email address to ask him, so has anyone else built an HBR-8? and what do you think of it as a nice cw receiver?  I know 'nice' is subjective :))))

Thanks guys for the suggestions and advice.

Well, I just had to get in on this since I pondered just the same question last year.  What to build.

The method to my madness is just what has been suggested and I made it easy (or easier as the case may be) to perform the upgrades as I see fit.  I started with what resembles an 8 tube version.  I used old command set parts and infact some of them are from Don Merz's stock.  What is kinda unique with mine is the upgradability.  I used the cabinet, front panel, and chassis from an old HP noise meter found at Dayton in the test  equipment junk pile for $3.  The vernieer is first rate, the panel is laid out with controls, a beautiful large meter that I used for the S-meter, and the chassis and cabinet are made to order.  What I did with the chassis is what makes it great to work with.  I cut out the insides of the chassis and made "drop-in" sub chassis for major blocks of the receiver.  This way when it comes time to upgrade or add a "block" to get closer to the HBR-16 I can do so.  It also allows me to have a receiver that I can listen to as I build a new or improved "block".  Neat, eh??  So far my HBR is just that.  MY HBR in that it follows some of the HBR concept but what I presently have is a dual conversion "command set".  Works good and now I have a basis for comparison as I add improved circuits, additional stages, etc. and as I said before depending on what I am doing I might also be "using it" as I am upgrading it.

Scott,

Quit worrying, and pick up the soldering iron.  Get a chassis, recommended
for the HBR-11, and build the "8" on it.. then you can put the rest of the
goodies on it to make it into the "11"... matter-of-fact, the April 1963
article about it, is named "The HBR-8 becomes the 11".  Besides, you'll have
all the coils wound already, and the rest will be easy.

As those idiots from NIKE say....

"Just do it"

Yeah Tom I'm going to take a close look at the March 63 QST for the HBR-8 tonight, and the April 63 issue for the 8-11 article.  I do like the idea of building the simpler version first and yet be able to expand the receiver into an 11.  One thing I'll be looking closely for is a drilling template for the 11.

Message-ID: <00a101c53c7b$c5d5e320$6602a8c0@dailey>


My HBR-11 came to me via an ordinary flea market in Denver.  It was bought, along with several other pieces of "junque" from a seller, by KG?HS (Carl) out here.  After a few weeks, Carl asked me to look at "this thing", as it was missing a tube, and had no markings as to what it was.  Finally, he just gave it to me, as he felt he'd never get around to messing with it.

I kept it under the bench for about 6 months, until one day I noticed the slipped Dymo label, under the lip of the cabinet, saying "HBR-11".  I had figured out by this time, that HBR meant "Home Brew Receiver", but still didn't know much about it.  

About that time, I received yet another complimentary copy of Ham Radio Trader, which was still being printed back then.  In it, I found an ad by Charlie Brenner (WB9GJW) for an "HBR-16".  Figuring it had to be a cousin of the "11", I emailed him.  Charlie was WONDERFUL enough to send me:  the ORIGINAL QST articles, a copy of "HBR Notes" (original version), A Full schematic, and copies of the ORIGINAL cut-sheets of the tuning capacitor, & the J.W. Miller I-F cans.  Armed with this info, I determined the missing tube, and brought it up s-l-o-w-l-y with my variac... Joila'... NOISE!  After repairing about 14 different problems, mostly solder joints, 2 tubes, and loose hardware, I aligned it with an HP-606 (one of the few that will do a 100 kc signal), and it was terrific.  I should mention, that all I had was the 40m coil-set.

About a month later, I found another piece of Dymo tape under the wiring, and it read "WA?LJO".  I looked the call up in an old callbook, and found that it belonged to Everett Huizinga - listed in Denver, CO.  (HEY!  That's where I LIVE!) I looked up the name in a Denver phone directory, and sure enough, there was still a Huizinga at the old address.  After attempting to explain why a total stranger was calling her about an old radio, the lady ultimately informed me "Oh my, that's my son... I think he was a teenager when he built that old radio!".  She gave my number to Everett (who now lived in Golden, CO - about 10 miles from me), and we spoke on the phone, finally promising to try to run into each other at the next hamfest.

It gets better...

At the Jefferson County hamfest, I was walking up to the front door, and I saw my friend Carl, with another guy.  Carl says "Hey, you wanna' meet the guy who built that receiver?"... I said "Sure!".  We spoke, and it came to light that Carl actually WORKED WITH EVERETT!  Imagine that... you buy an old radio at a "civilian" flea market, and it turns out that a guy you work with, is the guy who built it, back in 1965!.  Everett and I spoke, and he said to come over to his house later... I did.

Arriving at the house, Everett came out of his old garage bearing a small cardboard box... it still had the "ALLIED RADIO" label on it, postmarked 1965.  Inside was the treasure... the coil set for 20m, and 2 of the 3 coils for 80m, along with several BRAND NEW National 5-pin coil forms.  I've just found some No. 26 wire, and cut down an old 100 mmfd APC variable to 55 mmfd, so will be winding the last coil this weekend.

So, how's that for a story.  The amazing circular world of Ham Radio, and how Ted Crosby lives on.

Scott,

I totally agree with Lorne. Start out with the HBR-8 and get it working. 
Then add the additional improvements one tube at a time. The HBR-8 will 
actually work pretty decent on 80 and 40 meters and is certainly usable on 
20 meters. It's not much of a receiver above 20 meters. Make no mistake 
about it, the addition of an RF amplifier and an additional IF amplifier do 
make a difference, but the initial objective is to get the basic receiver 
working. If you don't anticipate tuning above 20 meters you can stop at the 
HBR-11. If you plan on using it above 20 meters, the Hartley oscillator 
makes a very worthwhile improvement. You have a real advantage in that you 
have a working set of coils from your HBR-16 and you can also use it as a 
model for your project. They're really very similar. Unless you have a 
quite a bit of building experience, I would suggest a larger chassis. It's 
pretty tight in there with the one Ted used. It will also leave you some 
room for future additions you might want to make.

Is it a decent receiver? Well, if you think the HBR-16 is, then you will 
think the HBR-12 is. There's no real difference in they're performance. I 
personally think both of them are excellent performers through 20 meters. 
They're very usable through 10 meters although the stability certainly 
begins to suffer on the higher bands.

Good Luck,
Darrell, WA5VGO

IMO there is so much interesting old stuff out there relative to the
number of people willing to get it going again that it's better to fix the
old stuff than to build something old from scratch.

I've been thinking about building the ultimate RX since 1968 but have
always ended up modifying stuff instead. and have been studying DSP and
digital radio lately. With the new, extremely small, shack, the 'old
stuff' distraction is being forced out of the picture and it looks like
I'm finally going to make some progress :-). Presently I'm looking at the
tradeoffs of the various sampling and digitizing schemes.  Stuff like
digitizer linearity, sampling aperture, and jitter limit 'ultimate' in
this world.

Of course, there are plenty of non-technical rationalizations for
constructing W6TC's design. It's easy to understand, it works well, it's
attractive to look at, especially if one were to use a National knob ;-).

As an aside, my dad acquired a 'collectible' CB rig the other day at an
estate sale and wants me to get the word out that it's forsale. He is a
yard sale/thrift store fiend! The rig is a Tram Diamonnd D201 with
original manual and D-104 microphone(mic was part of package when sold as
new). Make offer if interested.

Tom,

I would like to obtain a copy of the notes.  Happy to pay any costs if 
you wouldn't mind doing it.

Be a few daze [sic]..... it's snowing like a banshee, here in Denver.  25-30
knot winds and big wet flakes... oh, and snowflakes, too.

Mike,

Great site - their prices are very good, AND they have those planetary

You might want to read some of the feedback on OSE in the EHam section on 
product reviews.

OSE is certainly a mixed bag.....

Well, I broke down to-day & cleaned up the shack---took a day's vacation from work just to do it---got a real work-out putting things in order, believe me!

Anyway, with QSTs here going back to 1916, half the battle was getting THEM all sequenced again, & on the shelves...but after the dust of inventory settled-down, I noticed that my JANUARY 1969 issue of QST has gone AWOL.

Does anyone have a decent copy of same to trade...? I have some spare QST issues, a few going back to the 30's. ..maybe I have one here that you need...? Also have some 70's/80's POPULAR ELECTRONICS, & a handful of ELECTRONICS ILLUSTRATED.

Let me know if you have one to swap, please, with my thanks in advance...!

Message-ID: <20050426.094455.1868.0.windy10605@juno.com>

I received a nice letter from Clint Gorman, K4KRB. In it he indicates
that he built a HBR-14 when the articles first came out and he's like to
see if he can locate one (in any condition). I know there are a number of
HBR-16s and others out there and since I've owned a HBR-14 (don't have
one today) there may be another out there somewhere.

On another note:
I picked up a homebrew low wattage CW 80-10 transmitter which has a
Collins PTO (70E 8A) followed a string of up to four switch selectable
5763 multipliers driving a 2E26/6146 (power is sized for a 6146 and it
says 2E26/6146 in pencil next to the installed 2E26) into a B&W turret
band switch. The whole thing looks much like a Collins 310-B except the
tubes are miniatures vs the 6AG7s which the 310-B uses. The front panel,
typical for homebrew, has no markings. Does anyone remember an article
like that ?  The thing which really impresses me is that it's the exact
same size as my HBR-16 .....talk about a cool matching transmitter !!
 
I might bring it to Belton for a visual assessment.

There's at least one more. I've got one I picked up a couple of years ago. 
It's not a classic example. It uses 85 KC IF transformers and the guy that 
built it substituted some octal tubes for miniatures. He also took some 
pretty big liberties with the layout, although it works fine.
