Let's see if it's up..........

---------- Forwarded Message ----------

Thanks for the reply Kees. Since the site is down, do you have any suggestions for a circuit to use for a bfo   injection oscillator and the parameters for winding the coil, say a hartley, and at what point the tap comes   off. I have heard that the hartley generates lots of harmonics. Would a colpitts be a better choice, I  found a .455 khz colpitts that was used for the injection to a balanced SSB modulator in Orr,s handbook.  I forgot, all of this pertains to an HBR receiver and making a BFO for a product detector. If you don't have   time to respond, I understand, most us have little time for our selves. Perhaps you have some e-mail  address,s of some of the more active and current HBR builders. I'm trying to get started on my first one.  I have many pertinent parts for building just about anything, including the infamous Eddystone dial. When they get the site up, I need to figure out how to make postings to it, so I can get some help from the   hams that have been there and done it, so to speak.  Thanks agn  Regards John Marshall

Sometime back, Walt Hutchens suggested the grounded cathode Colpitts to me. 
This is the way to go. Since the feedback comes from a capacitor divider, 
no feedback tap is necessary. An old if transformer works perfectly.

It was good to read about Ted Crosby the HBR in this month's QST.  A few things were said about W6TC that I hadn't read and therefore didn't know...but can certainly identify with.  Some of my instructors in school could be just as critical (but always helpful).  Ted passed on just about the time I got my first ham ticket, and as a kid living far to the North there was little chance of my ever meeting him...and it's a shame that it took all these years for me to 'discover' the HBR.  So it's good that those who had the pleasure took the time to share with the rest of us.

....now If I can ever get this damned ATU finished and off the workbench, I might just be able to get back to MY home brew receiver...

Subject: [HBR] HBR16 memories
Message-ID: <C5974F4D.2BB6%alancfios@verizon.net>

A great big "thank you" to John Dilks for his article in QST this month on
the HBR16.  I was licensed in 1958 at the age of 13 and I remember building
and operating the HBR16 when I was 16.  It was a wonderful project and it
actually worked!  Although the correspondence is long lost, I remember
getting several letters from Ted Crosby helping me through the project -
especially those COILS.  I have no memory of whatever happened to my HBR16
but I sure would give a lot of money to know where that Eddystone dial went.
It was a beauty.
Thanks again for a nice trip down memory lane.  Who knows, maybe when I
retire in a few months (years?) I will build it again and come full circle.

Message-ID: <49723EBD.6040706@ARRL.NET>

Does anybody have the panel and chassis layout for the HBR 16?   I can 
estimate from photos, but it would be nice to have same measurements as 
Ted Crosby.


I found a new, Eddystone Dial in my junk boxes of stuff.  I must have 
bought it years ago, never opened it, and forgot I had it.  With that 
dial, I thought I might set out to make the HBR 16, with various updates 
published in QST in 1960s.



Most importantly, I like the cabinet used by Lee Craner's HBR16 in Feb 
2009 QST.  What size is the cabinet and front panel?  Looks like  8 3/4 
or 10 1/2  inches.



If I decide not to build HBR 16, then I shall sell Eddystone Dial.

Guys,

I am happy to send copies out, and have already done so to several hams who have asked, but I do need an email address.  I do not want to broadcast to the whole list, just to those who are interested.  If there is a way to get the address from a name, perhaps someone can tell me how to do it.

  Guys,

  I am happy to send copies out, and have already done so to several hams who have asked, but I do need an email address.  I do not want to broadcast to the whole list, just to those who are interested.  If there is a way to get the address from a name, perhaps someone can tell me how to do it.

Message-ID: <49723898.8000402@OLG.COM>

Does anybody have the panel and chassis layout for the HBR 16?   I can 
estimate from photos, but it would be nice to have same measurements as 
Ted Crosby.


I found a new, Eddystone Dial in my junk boxes of stuff.  I must have 
bought it years ago, never opened it, and forgot I had it.  With that 
dial, I thought I might set out to make the HBR 16, with various updates 
published in QST in 1960s.



Most importantly, I like the cabinet used by Lee Craner's HBR16 in Feb 
2009 QST.  What size is the cabinet and front panel?  Looks like  8 3/4 
or 10 1/2  inches.

What a pleasure to see the list becoming a little more lively and
perhaps there are even going to be some more HBR projects.  And I'm
looking forward to being able to post progress more easily, now that
'The Bat!' is allowed as a mailer.

My 'transformerless' HBR variation went well up to the time I
discovered that it was about 40db short of sensitivity.  In the last
post I was thinking the problem is in the IF stages.

However when I measured the gain, stage-by-stage, I found that
the mixer stage had a conversion LOSS of about 20 db. That is, it
takes about 10 times the voltage at the mixer signal grid compared to
the mixer output to get the same receiver output. OOPS!

I've used this same 'push-push' mixer circuit before; typical gain is
~+6db. That is, 26db better than I'm getting here. I won't go through
all the things I've checked and changed -- tubes, IFTs, voltage
checks. No sign of a problem.

I have been using the triode halves of the two front end 19JN8s as a
mixer. (Pentode sections are RF amp and ECO, respectively.) Finally, I
laid out the triode section tube characteristics charts side by side
with those of some tubes I've used successfully. Ahha ...

Down close to the zero plate current line (where mixers have to go
to mix), the successful mixer triodes just cut off. The gain stays
relatively constant (lines of constant grid voltage remain nearly
equally spaced) until the tube cuts off sharply. But the triode halves
of the 19JN8 are effectively variable Mu: the grid voltage lines curve
and bunch together so that as cutoff approaches it takes a much larger
grid voltage swing to produce a given plate current change.

D'oh! (slaps forehead with base end of 9-pin tube) These tubes were
intended to be used as oscillator/pentode mixers in FM sets or in
applications in which the triode was operated with small signals and
well within its linear range. In a class 'C' oscillator, a variable mu
characteristic helps reduces harmonic generation.

And here I thought all triodes of similar Gm, voltage gain, and supply
voltages were pretty much alike ...

Needless to say there are VERY few choices of triode-pentodes with a
0.15 amp filament, some of them have common cathodes for the two
sections, and I'd bet that all of them were intended for
oscillator/mixer service. I will review this point today, but it looks
like I'm going to be rearranging things a bit. I think there's space
to add a separate mixer stage: I have used both the 12AT7 and 19J6 in
this application before.  The 'J6 data sheet specifically refers to
mixer service with plates in parallel.

This would require changing the two front end tubes to single unit
types (say 12BZ6 RF and 6BH6 oscillator) in order to pick up the
necessary filament volts. These are 7-pin types so socket changes
would be needed. I guess it's worth looking for a 9-pin pentode with
an 0.15 amp filament, but I don't have a good feeling about that --
9-pin pentodes came later and tend to be high gain tubes with higher
wattage filaments, not aimed at six-tube AM/FM radio applications.

It's not likely that I'll have enough gain even WITH the mixer change
but it'll be in the ballpark and there's still room for improvement in
the RF stage and probably in the IF's, too.

In other news, I did get the dial lighting installed: Four Radio Shark
12-volt 25 ma. bulbs glued in holes in aluminum angle stock supported
on the Eddystone 898 dial mounting screws and in series with a 3000
ohm resistor did the trick.

The message limit is 40KB so it kicked the message back. I approved it, so lets see if it goes through now. Also the QSL reflectors do not like attachments. If you can put it inside the note it will go.

Apparently Scott, KA9FOX, has the QSL/QTH reflectors set up a little differently from Al Waller. The hit counters on the websites also started working.

David, 

I'm up here in Rochester NY. I might have that template. Am not sure though. I have most of the items in stock to build my HBR16 or maybe the 13C. Anyway, it will take some time for me, because I'm up to my armpits in work, at work. Am out of town for a good week now and will be out of town on other occasions through middle of March. Keep bugging me and I will scrounge around in the basement for the template. It might be larger than the one for the smaller box, I believe. 

ciao

Does anybody have the panel and chassis layout for the HBR 16? I can 
estimate from photos, but it would be nice to have same measurements as 
Ted Crosby. 


I found a new, Eddystone Dial in my junk boxes of stuff. I must have 
bought it years ago, never opened it, and forgot I had it. With that 
dial, I thought I might set out to make the HBR 16, with various updates 
published in QST in 1960s. 



Most importantly, I like the cabinet used by Lee Craner's HBR16 in Feb 
2009 QST. What size is the cabinet and front panel? Looks like 8 3/4 
or 10 1/2 inches. 



If I decide not to build HBR 16, then I shall sell Eddystone Dial.

I have a complete set of  "HBR Notes", but they're only for the HBR-11... 
should somebody want a copy, they need to send an SASE (8.5 x 11) with 
adequate postage for 7 ounces).  I'd be happy to copy 'em for ya.

No - I don't have them on an electronic file.

I have some original correspondence from Ted to the builder of one of the 
HBRs I own. He certainly was generous with his time and coaching.

All the HBR Notes are on the HBR and More CD ($10 postpaid). I used to have them on the web site but it took up too much room. The pictures I left on the web site.

Bill,


Thank you for response.  I very much would like the templates.  But I 
have done pretty good looking at pictures.  If you recall the one 
kilowatt one band amplifiers in the ARRL Handbook, during the 1960s, I 
liked their layout of front panel.  So I made my best estimate, and 
reproduced some of them, and made  modifications.  I always liked the 
single band kilowatt concept because it lent to ability to modify 
design.  I changed the PI network output to a PI-L network.  PI network 
gives about 35 dB attenuation on second harmonic, whereas PI-L gives 
about 52 dB.  I also built a four tube (813s) amp for 160 meters.  Some 
photographs are at:


www.QRZ.COM/W3HYM


It would be nice to see exactly how the receiver was laid out.  I plan 
incorporating some of the modifications that came out in the 1960s.  
Also, I want to have band switching built in for 6 meter converter, 2 
meter converter, and maybe 1 3/4 meter (222 Mc) and 432 Mc.  Thus, I 
want my "dial" calibrated for at least 6 and 2 meters.  I think it would 
be neat to do some 6 meter sporadic E, or 2 meter moon bounce, with HBR. 


By the way, I had the pleasure in high school to live near QTH of Sam 
Harris W1FZJ.  He then was editor for QST World above 50 Mc.  He was 
very friendly when I visited his QTH.  We did some interesting Saturday 
or Sunday afternoon projects.   For example, one visit we  made 
polarplexers for 10 GHz, using  reflex klystrons, a pipe for waveguide, 
and 1N23 diode.  A "flying saucer" kids used for sliding on snow made a 
good  parabolic reflector.  I learned a lot that day about microwave.   
Well, that was my first HBR for microwave. . . . .


I found my Eddystone dial.  It seems a lot easier to use a National 
Dial.  Is there any real advantage with the Eddystone dial?   I am 
debating which way to go.


I have enjoyed reading the many posts on this reflector.


73,


David

David,
If you have an Eddystone 898 and the room, use it, no question.
If you have an Eddystone circular dial, it's much better than the National dials because of the Ball Brother's vernier drive. If you have a National ACN or ICN circular dial replace the mechanism with a Ball Brothers vernier drive (used on all the Heathkits and others). You will be amazed at how much smoother the tuning is and it's a slightly better ratio, Instructions in the Hints and Kinks section.

I think  the Eddystone is horizontal from shape of the box.  It was in 
storage, I found it, and put it in the garage.  Still not opened from 
1960s.


Where do you get Ball Brothers vernier drive?  Is this just the drive, 
no dial?  I was thinking maybe for the home brew XMTR VFO.

David,
The Eddystone 898 is a weighted slide rule dial, MUCH valued by builders. Don't be surprised if someone tries to talk you out of it, They talked me out of mine, but I didn't want to build a HBR-13C, too fancy.
The Ball Brothers drives (just the vernier drive) I think are still available because I've seen them advertized on the boatanchors reflector ....best to just ask there....or ask here. There are probably cheap copies out there too. I usually pick them up in old Heathkit junkers ....lots of parts rigs ouit there under the tables at swapfests. By the way, the Heathkit LMO assemblies make great VFOs. The best (my opinion) tuning mechanism is still the anti-backlash worm drive out of a BC-221 which you can pick up at swapmeets for <$10. Just a little more difficult to mount. That mechanism was used on several older transmitters and receivers. The homebrew LWM-3 Transceiver comes to mind. 
Walt and others probably has some good ideas too
I don't know how simple/complex of a transmitter you are looking for.

I agree the BC221 dial drive is excellent although a little cumbersome to use.
Any of the LWM 3's I have seen, used the fine command transmitter capacitor and dial set up. These are excellent and still fairly easily obtained and  should not be overlooked by homebrewers.

Boy, this forum is getting very lively since that Feb QST article submitted 
by Jay Helms, W6HHT.  Jay is in the final stages of putting together the HBR 
Adventure book in a CD PDF format with a lot of information that hasn't 
heretofore seen the light of day.  If anyone has any letters or other correspondence 
from Ted, I am sure that he would appreciate receiving it and possibly using it 
in his book with appropriate credit.
 
I don't have his e-mail address handy but I could find it if anyone is 
interested.  E-mail me at w6ph at aol.
 
I also want to plug Kees' CD of HBR notes.  It has a lot of stuff of interest 
to the prospective HBR builder.
 
One more item of interest is the ARRL QST archives that are now available to 
members.  The files are in PDF format and can be printed very easily.  This 
will make it easy to get the original W6TC QST articles.
 
Not Ted Crosby related, but I really appreciate Walt Hutchens' (KJ4KV) 
narratives on his problems and solutions in his own HBR.  You don't get this in 
textbooks.

Introductory cliche: The dial you want really depends on what you're
trying to do.

When building an HBR-series receiver, both the National ACN (and
relatives) and the Eddystone are 'authentic': Ted Cosby built with the
National dials but many other builders used the Eddystone.

Advantages of the National dials are mainly ease of layout and
construction. They're also fairly inexpensive when you can find them.
The standard ratio is around 5:1 or 6:1 which, if you're tuning a 500
kcs band in that 2-1/2 turns is MIGHTY fast for tuning SSB. They're
satisfactory, however, for a vintage radio night set that will be used
mainly to receive AM.

An upgrade is the use of a Millen dial having a two-speed drive,
typically 36:1 for most of a knob revolution, then 6:1 thereafter.
Quick QSY but you get a slow enough rate for tuning in SSB when you
arrive.  These are planetary ball-type drives.

Jackson Brothers makes (made?) both a single-speed version of the
drive assembly for this dial and a two-speed one. They were available
in the U.S. (UK company) not long ago, maybe still are. These drives
with a home made dial scale and frame are an excellent combination of
construction practicality and good performance.

Planetary ball-type drives (and dial assemblies) are available on many
inexpensive junker sets but they are frequently worn to the point
where backlash will be annoying. A good bet if going this route is an
FT-101 series junker since the (single speed) front end tuning control
drive got a lot less mileage than the main tuning knob on other sets.
Metric dimensions on this set, for example 6 mm shafts. The Sideband
Engineers SB-34 sets are pretty common as junkers and they have the
two-speed version of this drive, though it's often worn.

Worn planetary ball drives can sometimes be much improved by pinching
the fingers that hold them together VERY SLIGHTLY with a pair of slip
joint pliers.

Planetary ball drives can require significant torque.  It's best to
mount them so that is transmitted to the panel rather than to the
chassis or (worst of all) the capacitor frame, to avoid backlash
issues.

If your metalworking skills are new or rusty, I'd say pick one of the
choices above. There's nothing more frustrating than being unable to
get the parts in the right place without chewing up a lot of chassis
and/or panel. The two speed planetary ball drives really can't be beat
for performance AND (with proper pointer and frame) vintage appearance
on an HBR-type set.

Layout and construction is straightforward: Set the capacitor on a
hard flat surface, measure the height of the center of the shaft, then
mount the panel temporarily on the chassis and measure up the same
distance. Be sure the chassis is FLAT. Use a flex coupling between the
dial and the cap but get perfect alignment so the coupling has no
visible work to do.

The tuning cap should have the lowest torque requirement possible,
consistent with no shaft side play. When the tuning cap is mounted
flat to a large chassis it's generally a good idea to stiffen the
chassis where the cap is mounted by epoxying a plate on the underside.

The Eddystone 898 is the top of the line for performance with strictly
vintage parts. 55:1 ratio, flywheel, sliderule type with logging
scale, can be lighted, very smooth. The 898 is, however, a four-star
B***H to lay out properly and install. There are basically three ways
to go about it: 1. With the cap shaft far enough above the chassis so
the flywheel doesn't hit -- easiest but a VERY high tuning knob. 2.
With clearance cutout in the chassis for the flywheel -- better knob
height but more work. And, 3. With the chassis spaced back from the
panel enough to clear the dial mechanism.

These are hard, harder, and a real mess, respectively.

Eddystone HBRs are laid out somewhat differently than the original
ones but that has all been worked out and the info is in the list
archives and/or on the CD.

Another possible avenue is old junker broadcast radios, particularly
the better models that had slide rule dials. While not a match for the
Eddystone, these can be quite good and they're both cheap and not too
hard to find.

The command set dials can't be beat for quality -- scissors-type
gears, and so on.  They were designed for a single scale (single band)
so they're not a great fit to an HBR project, but it can be done.
They're much better for a set where the main tuning is a tunable 1st
IF so only one calibration scale is required.

The big problem with multiple dial scales is that the knob shaft is
off to the lower right but close to the dial hub so you have a lot
less room for scales than you'd have with a central knob or one set
further off.

The command dial drives are integrated with a three-gang tuning cap
(receivers) or single gang cap (transmitters). You can, however,
remove the 'works' of the cap and install your own in that space. With
the dial on the front panel the capacitor shaft is PARALLEL to the
panel so the usual HBR layout requires considerable rework.

I made a dial for a miniature set from the drive for a command set
control box. This gives you a gear reduction drive with a
make-it-yourself pointer and an output shaft that's perpendicular to
the panel. There's metalwork but it can be done with hand tools and a
drill press. Quality isn't quite the equal of the command set itself
(gears are smaller) but it was entirely satisfactory.

With completely home brewed dials, the sky is the limit but the
metalwork can be a challenge. Browsing old radio construction magazines is
probably a good way to get ideas.

Jackson Brothers drives are still being manufactured.  They also will repair 
their old drives.  Check them out at 
www.mainlinegroup.co.uk/jacksonbrothers/index.htm.

The dual ratio Jackson Bros drive can be mounted in a National ACN/SCN/ICN 
drive quite effectively, resulting in a classic look with smooth dual ratio 
tuning.  I have pictures on how I did this to my HBR-16 that I'll pass on to

WALT,


Are these the Jackson verniers, dual reduction ball drive, that you 
mentioned?   Did you mean they work with National Dial, or Millen Dial?

Yep, that's them.  You can find them more cheaply in other places,
when you can find them.  But making stuff like this is classic 'buggy
whip' industry -- there's unlikely to be more than one supplier and
when he goes down for any reason, it's over.  If you haven't got one,
this is a good 'lay away' item for future projects.

Most of the National and Millen dials are compatible, I think --
others here are more expert than I, but I think that most are just
frames with a drive like this set in the middle.

OK.  I shall do just that, maybe get two.  I think dail reduction with

Another problem solved ...

In the last edition it appeared that the reason the mixer gain was
about -20dB (instead of maybe +6 dB) could be that the triodes I was
using were not suited to mixer service. Sure enough I was unable to
find a 0.15 amp filament triode-pentode with a triode that was better.
So the 19JN8 RF-1/2 mixer and 19JN8 osc-1/2 mixer became three tubes:
6BH6 RF, 12BZ6 osc., and 19J6 mixer.

This required punching another socket hole and making up three '7-pin
but fits in a 9-pin hole' sockets, with aluminum scraps and JB Weld.
Because these three sockets surround the tuning cap, I mounted them
about 1/4" above the chassis to allow airflow up from below to carry
away the heat. The pins project down through the socket hole just
enough to allow wiring in the usual way. The wiring rearrangement was
easier than I expected.

The 6BH6 -- a sharp cutoff pentode -- may seem a slightly odd choice
for the RF stage, but its cutoff voltage is close to that of the
pentode halves of the 19JN8's used for the IF stages. That means that
(as AGC voltage increases) the gain of all three stages is reduced more
or less equally so there's less chance of causing distortion due to a
big signal getting through the RF stage and hitting a nearly cut off
IF.

Sure enough, the 19J6 is a FAR better mixer tube than the triode
halves of the two 19JN8s.  I haven't measured the gain, but it's in
the range -- the radio copied the Saturday night traffic on 3885,
FB, with some S-meter readings way up the scale.

I'd sure like to know the history of the 6J6. It must have been
developed around 1939-40 but it is YEARS ahead of the surrounding
tubes on the nomenclature charts: think 6F6, 6G6, 6H6 ... 6K6 ... It
was (to the best of my knowledge) the first serious UHF 7-pin
miniature tube, being rated to operate as a mixer at 600 Mcs and
working fine as an oscillator in the same territory. I think it
appeared for the first time in the BC-788 radio (radar) altimeter.
That was in production in 1942; I don't know how much earlier.

I believe the BC-788 is a GE-developed set; whether they also designed
the tube, I don't know. I wouldn't expect RCA to have done anything
quite so innovative. I pulled out a BC-788 junker set to get the value
of the cathode resistor for the 19J6 mixer.

Anyway, the little HBR project is basically working: The overall gain
is in the ballpark, though probably still just a few dB low.
Furthermore there's no trace of regeneration or oscillation (with the
RF stage re-arranged from grounded-grid to the usual grid drive
circuit) meaning that moving the mixer to its own tube eliminated some
unknown feedback path.

There's just a little audio distortion, probably in the plate detector
stage. The next step there is looking at the detector output waveform
with a scope and (probably) tweaking the operating point.

The octal sockets I used for the coils hold them firmly but because
the pins don't fit tightly enough in the socket the coils flop around
some. That's fine for the RF and mixer coils but not so fine for the
oscillator: I've picked out a ceramic socket that doesn't have the
problem and will make a swap.

There's a little too much low frequency audio response. It drifts
about a kc downward during the first hour or so -- I've made no
attempt to do compensation.

The band edge marker and BFO stages aren't wired yet. It will need
coils for other bands.  In other words, lots more to do.

I've gone looking for the early photos. They were lost during some
update of our website but I'm told they can probably be found, when
Sharyn has time in a week or two.

Ludwell Sibley's _Tube Lore_ says that the 6J6 number was registered
in September 1942. The 6C4 miniature was registered a few months earlier, in
May 1942. Another miniature good for VHF/UHF stuff was the 6AK5,
and it was a few months later in May 1943. I'm guessing the
9001/9002/9003 miniatures must've been about the same time
but I don't think they were registered the same way; tubemuseum.org
says 1940.

There were earlier flexible-wire-lead "peanut tubes" going back to
the 20's and 30's, but it looks like to me that RCA at least was
concentrating on the "acorn tube" for UHF purposes - the sockets
for those look incredibly unwieldy.

Actually, the acorn sockets were very tough, and HELD ON tightly.  They were 
used in all sorts of BC goodies and were the ORIGINAL "UHF" tubes.  An 
interesting article about a HB transmitter (using them) appeared in ELECTRIC 
RADIO a couple of months ago.

With changes in the plate and cathode resistors, the linearity of the
plate detector (and sound of the receiver) is now okay.  It probably
can be a bit better, with more study.  The acid test is listening:
I'll know a more in a few days.

There doesn't seem to be a crossmodulation problem because it sounds
just as good during peak evening hours as it does in the middle of the
night.

The HBR-type coils are impressive: The Q's are WAY up there, and that
means that off-frequency signals are attenuated before they can cause
crossmod trouble in the front end.  I did use #22 wire for the RF and
mixer coils rather than the #26 (I think?) recommended in the
instructions.  The 160M coils will have to go to the smaller size,
though.

Further revisions to the detector stage will be needed when the BFO is
wired, since there's no good place for BFO injection in the current
circuit.

It needed more gain. I figured the IFTs (remember, 100 turns of #40
wire on a 9/32" form?) were a bit Q-challenged, so that was the first
thing to be looked at. I had a pi wound coil that was self-resonant in
the BC band: By removing about 2/3 of the turns I was able to adapt
that to use with a 50 mmf shunt cap at 1700 kcs as a replacement for
the 2nd IFT. In the original, the shunt cap was 150 mmf. Higher Z =
more gain, even without the higher Q.

That gave a good boost but considering that higher bands typically
have less front end gain, even more would be useful. I'll try the
same again, with either or both of the 1st IFT (which drives the
half-lattice filter) and the 3rd IFT.  I can also optimize the mixer
cathode resistor for slightly higher gain.

For an HF receiver, you want no more gain in the RF stage than needed
to cover up mixer noise -- very little when using reasonably modern
tubes. (More of an issue if you're into using 6K8s ...) The big
problem on these bands is overloading the mixer and/or RF stage,
causing crossmodulation. Necessary total gain can be made up further
along, usually in the IF stages.

The ceramic socket I was planning to use for the oscillator coil
turned out not to quite fit the hole -- the mounting screw holes are
too far apart.  I found an Amphenol MIP socket that fits AND holds the
coil solidly.

When pulling the shield plates in the 1st IF grid and crystal filter
area I discovered a joint that had never been soldered ... no wonder
it was sometimes noisy if tapped. However, I wired the filaments of
the three new tube sockets without a single mistake ...

With the two crystals 1.5 Mcs apart (1700 kcs +/- 750 cps) the
bandwidth is just about an ideal compromise for a receiver of this
type.  It'll copy AM okay (though typical AM round tables require
occasional retuning) and isn't much too wide for SSB.

Total receiver plate current is around 40 mA.  The IF stages are about
7.5 mA plate+screen.  A few more mA will be needed when the BFO and
marker oscillator are wired up.

Walt,

What is the first IF, and what is your mixing scheme for the 160 meter coil
set?

1700 kcs is the only IF -- I'm using a 1700 kcs half lattice crystal
filter right after the mixer.  So it's not 100% authentic HBR.

I plan to have the LO tune 3500-3700.  Should work ... shouldn't it?
It's not ideal because extremely strong 80M signals could cause
spurious responses, but these receivers are a compromise design, and
with high Q coils, I don't think it'll be a problem.

Hi, Walt,
I was reading your latest post about your HBR receiver.  

Just curious, for 40m/80m are you planning on running your VFO from 5.2 - 5.7 mHz, picking up both bands and just changing out the front end coils?

I thought of doing that but the Eddystone 898 dial that I'm using
comes with a pre-printed scale for each of the six bands -- it seems
to have been part of a kit of front end parts for a very conventional
British home brew receiver design: G3RWW maybe? (In the RSGB Radio
Communication Handbook, 4th edition.) The dial scales look good -- I
couldn't do them nearly as nicely, starting from scratch -- so I'm
pruning coils (etc.) to use those scales and the 40M band is 7.0-7.3
over roughly the same distance as 3.5-4.0.
