Brian,
 
You definitely found a gold mine!  You should be able to identify the  
receiver yourself by going to the HBR web site.  It looks like a classic  HBR built 
right from QST, but I'm not expert enough to tell you which one it is  exactly.

Brian,

It appears to me to be an HBR-13C, as presented in QST for October, 1965.
Designed by  Alex Stewart, a friend of Ted's. This is not the one shown in
QST, but it is almost the twin.

I have a strong interest in this particular HBR, as I have all the parts
except for one of the two T1s, a Miller 1730. (If I don't find one, I will
improvise.)  I do think this is one of the better designs of the series, and
I congratulate you on finding it.

Good luck, es 73,

Bill Fizette,  w2dgb

Kees,

My regen-superX receiver at 
http://www.io.com/~nielw/3tube_xtal/3tube_xtal.htm evolved from the two 
tube superhet shown in the early 40s handbooks. This design used 1/2 of 
a 6C8 dual triode as a regen detector. When I first built this 1940s 
design I didn't like the stability and overload handling of the triode 
regen IF detector. I immediately added a BFO. One mod lead to another 
and I ended up with a 6J7 regen detector with feedback in the plate circuit.

It was an easy mod to replace the 6J7 grid coupling cap with a crystal.
This simple crystal filter does not include the usual phasing and 
selectivity adjustments.  Max selectivity occurs just before the 
detector breaks into oscillation and the peak is at the xtal freq. By 
varying the BFO freq wrt the xtal frequency I change the pitch of signal 
at the peak.

I can use the regen action of the detector to copy CW but I lose control 
over the crystal filter characteristics. Having the BFO let me vary the 
amount of selectivity (by varying the amount of regeneration without the 
detector being in oscillation) and apparent peak frequency (by varying 
the BFO frequency).

73,
Niel

Yep 6K8. I got a couple and was just wondering if anybody had used one and

The problem with multigrid mixers like hexodes and heptodes* is that they're 
noisy. They have lots of conversion gain and are more immune to pulling than 
most other mixers, but the noise can't really be cured because it's a function 
of all those grids (partition noise).

The classic fix was to precede the mixer by a stage or two of low-noise RF. 
This works but it puts more gain before the selectivity.

Still, good receivers have been built with those tubes. The Drake 2-B and 
Collins 75A-4 are two examples.

One big difference between the 6K8 and other multigrid mixers like the 6L7, 
6SA7, 6BE6, and related types is that the 6K8 has a separate triode unit for 
the oscillator, so that one tube can be used for both oscillator and mixer 
without the problems of the 'self-excited' pentagrid circuits. 

The best use of the 6K8/12K8 I know of is in the ARC-5 receivers.

73 de Jim, N2EY

* A 'heptode' is a tube with seven elements, not a beatnik amphibian.

Yes... "nice" is most assuredly an UNDERstatement.  Make's my old HBR-11
look like the scrapyard version... still, readable & usable cw at .045 uv on
80m & 40m goes a long ways past pretty.  You got a "find" there, Brian

Guys I've had tons of emails for this radio, over eight from one guy. I 
can't possibly answer them all. And to all I didn't answer I am sorry. I was 
hoping it would be simpler but that's life. I know there are several of you 
that are very interested in buying the radio so to make it fair and easier 
on me I've listed it on Ebay . My reserve is $350 and I think it's worth 
that easy. I have a Buy it now of $375 because that's what I want for it. 
Plus this way I know if someone bids they are serious and not just wasting 
time.

to

Message-ID: <00cf01c68c78$a4a097b0$f4305a45@CompaqS5000>

Good Morning All,

I think I may well have stumbled upon yet another application for the good ol' automatic dishwasher in the kitchen...CLEANING BLACK, WRINKLE-FINISHED COMPONENTS...!

Specifically in my instance, the absolute spic & span cleaning of an old, SEALED, 10-henry filter choke. I agonized over how I might best clean this thing (wrinkle finishes drive me nuts!), when it dawned on me: why not just put it inside the dishwasher with the next load & see what might happen...?

VOILA! It came out absolutely SPOTLESS! I made sure I pulled it out just before the washer went into the heat/dry cycle, though, for fear of the thing either (A) exploding (it IS a sealed unit), or, (B) cracking the porcelain insulators surrounding the two electrical terminals...

"FYI"

So what's your point John? I've had girl friends that didn't last as long! 
The reality is I've been wanting the Eton E1 for some time and I needed the 
money to get it. I would have liked to had my cake and eat it too but that's 
not reality and something had to go and I'm not a Ham so a ham band only 
radio isn't as appealing as a general coverage rig. I bought it because it 
was very interesting and I wanted to see first hand what a HBR looked like 
and I did and it was amazing. I'm going to give you the benefit of a doubt 
but it sure sounds like your trying to put me in a bad light.

Yep... that's why I love my Old Ugly (HBR-11).  Wrinkle black steel case,
with the controls sort of in a straight line, but well... not really.
Nobody wants it but me, and that's just fine.  Ebay... I think not.

Subject: [HBR] Dallas HamCom
Message-ID: <20060611.115227.2692.2.windy10605@juno.com>

This year HamCom was held in Plano (just north of Dallas)

HamCom this year was pretty good but had terrible parking with a remote
overflow lot and too small of a shuttle bus. The line was 30-50 people
long and the bus could carry 15 (they had 2 busses). Also it's real
difficult to transport items via this route. We found closer in parking
but one of the areas people used was tow away. 

The seminars looked very good but none of our group went to any (not
enough time) and wanted to spend most of the time in the swapmeet areas.
The inside individual swapfest was too small, the big vendors did OK but
they only had 48 table available inside which we thought would be a major
problem. However, the problem was solved by having tables in the
courtyard and around the outside of the building where it was total shade
....not bad at all. The outside parking lot area was about as large as
previous HamComs and consisted of 2 double parking lot rows ....and they
had another double row available....and it had shade trees which is quite
an improvement over previous HamComs. There were also VERY few non HAM
sale items ....hats off to the organizers (computer parts, jewelry, etc)
....the cookie table counts as HAM. Since they also opened for most of
Friday and we were only there Saturday, I talked to Richard Cobb who is
the guy who buys anything, especially boatanchors   .........and stores
them. As we sat on the tailgate of his pickup he said it's one of the
best HAM swapmeets he'd been to and he goes to ALL of them. He said
Friday "there were lots" of 75A, 32A, 75S, 32S Collins equipment, Johnson
stuff, RME 6900, SX-28, Halli, etc equipment. In the back of his pickup
were 3 Valients, 2 Rangers, the SX-28, a 75A3, and numerous others ....it
was 3/4 full under his camper top ......again. There was one young guy
selling to contents of a freshly cleaned out classic --leaky-- barn with
critters ....piles of ARC-5 units in "good" to "terrible" to "chassis
only" for $5 or so. When I got there Saturday at 9AM it was pretty well
picked over but bought 7 units for $3 each. He had buckets of variables,
oil capacitors, trimmers, transformers, chokes, etc. I walked off with a
bag of variables and IF cans for $10. There was one guy walking off with
a large grundgey chassis he bought for $1 (that was his starting price)
......the chassis had a couple of transformers ......and a cylindrical
Collins PTO !. At 12Noon Saturday he auctioned off what was left (1/2
pickup full) starting at $20 total. When I went by at 12:30 the area was
clean. I saw two Johnson matchboxes for $75 each (one was like new),
SB-102 through HW-101 for $190 to $50, Handbooks 50s and 60s for $5 each.
Most of the Collins radios were at today's ebay prices but there were
some real deals on Friday.

Message-ID: <001601c68d89$db4843a0$bc305a45@CompaqS5000>

Good Afternoon All,

I keep being drawn back to Bob Raide's (W2ZM) article on Heising modulation, as was featured in the January 2005 issue of the AWA's JOURNAL...

I'd like to modulate my 1923-style Colpitts transmitter in a similar fashion, & I have all of the parts, with but one singular exception, i.e. the 1:3 audio interstage transformer which is used to drive the final modulator tube.

Does anyone reading this have such a unit languishing in their junque box that they might wish to trade for some other needed part at their end, that I might have here...? If so, let me know what you need, & maybe we could arrange a swap.

BTW, this unit is very similar to the old Stancor model A-53C transformer, if that might ring any bells for you...

Many thanks for your kind consideration...!

An idea:

Perhaps an old power transformer could be used. If we have, say, a 540 VCT 
(270-0-270) secondary, the primary-to-secondary turns ratio is about 1 to 4.9. 
Primary to half secondary is about 1 to 2.45.

Minor adjustments in ratio can be made by putting the filament windings in 
series or parallel.

If the single-ended driver stage draws significant plate current, it may be 
worthwhile to restack the laminations with an air gap rather than interleaved.

Of course even a small power transformer probably has a lot more iron and 
copper than is needed, but that won't hurt anything.

Just an idea - I haven't tried it out.

Eddy,

I have an interstage transformer for a Johson Ranger or 
Valiant for sale here. It is a new Hammond unit and 
I think might be  3:1 ratio. Let me check and get back 
to you and the group.

Message-ID: <449415C6.13097.28292BE@localhost>

Ebay has a couple of interesting items.   #9740437773 is a mostly 
stripped chassis with some parts.  Looks like it was a double 
conversion, single band receiver ... is that the cutout and front plate 
from an 898 dial?    This auction goes 'till Sunday evening, ET.  

#9740328677 is a homebrew five-tube regen shortwave set, 1.85-
30.5 Mcs, using plug-in coils.   The description is:

Built in power supply with solid state diodes.  Looks like a RF-
mixer-fixed tuned regen detector-two stages audio with the RF and 
OSC tuning controls separate.  Nice National 'velvet vernier' dials -- 
am I remembering that right?   Diagram, tuning charts shown in 
auction pictures.  A fairly nice job except for the speaker cutout 
which looks easy to fix or hide.  SOMEONE on this list needs this 
radio and there's only one bid.   Goes to about 3 PM Sunday 
afternoon.

My HBR16"E" arrived with its twin transmitter (a 20-75 meter HB SSB rig 
from the same builder) and looks like it will clean up very well. Does 
anyone recall what the "E" suffix to the HBR meant...or does it just

Hi Scott (and others),

I'm back from my West Virginia trip and have located the Amphenol coil
forms - there are 21 in the collection.  Now I need to locate the
variable caps that fit into them.  I know I bought a bunch of them many
years ago when I had thoughts of building the HRB receiver.  I also found
the winding wire.

First of all, I guess I need to locate the schematic for the HBR so I can
see just how many forms are needed. Maybe you can tell me.

Scott, I've had several others who are interested in the entire
collection of HBR stuff I have and I guess I may should consider them
first, but you are the one who raised this question - so I feel an
obligation to you too.  (What a dilemma)

I had thoughts of putting the entire collection up on e-Bay, but I've
never sold stuff there and really don't know how to start.  Some one
mentioned a website devoted to the HRB receiver and maybe I should look
there too.  Where is it?

Are you sure that you can't buy the forms from Amphenol?

I'm an octogenarian now, been a ham op for over 60 years and was a radio
"nut" before that - ever since my preteens.  I have a basement filled
with radio stuff and I need to downsize - in a big way.  You are helping.

Hi Guys,
 
Somehow or other I ran across the BoatAnchor group and recently saw a
request for nine clear Amphenol coil forms used in the HBR series.  Many
years back I bought 21 of these forms thinking that I'd build the Crosby
receiver, but with advancing age, job constraints, job relocations, etc.
I just never got around to doing it.  (And I was big time into building
stuff too)
 
To shorten this story, I probably have almost a complete set of HBR
parts, cabinet, chassis, tubes, Eddystone 898 dial, 21 coil forms,
Hammerlund capacitors for them, all the Miller IF and BFO transformers,
"S" meter, power supply parts, resistors, and maybe even all the fixed
capacitors - what have I left out?
 
Anyway, when I saw this guy's problem I let him know that I had the
Amphenol forms, but didn't want to break up the set in case someone else
was interested in building the HRB.  I mentioned that I was intending to
put everything up on e-Bay and he would certainly be welcome to have
whatever might be left over from the e-Bay sale.
 
Now, he wants to build another receiver and wants the entire lot of
parts.  He referred me to you to get some estimate of that it's worth as
I have absolutely no idea.  I may can find what I paid for some of the
items, but it'd be a lot of work digging through old records.  My memory
(and I'm now an octogenarian) says the Eddystone was about $20.  But when
I queried another group about the Eddystone one guy told me he bought one
on e-Bay for $10 and another guy says that he sold one for $135!  (What
is going on here?)  I never went into ham radio to make money, but would
not like to give it all away - just so I can come out pretty even-steven.
 
If this is too much of an imposition for you two then I do apologize and
will look elsewhere - I can always put it up on e-Bay and just let the
chips fall where they may.
 
What a great hobby has been and what it has meant to me for well over 60
years I can never put into words.
 
Best 73,
 
Doc, W4ITJ

How COOL!

The 75-20M combination was most often done by 'band imaging' 
with a 9 Mcs IF.   I see the 455 kcs IFT in one of your pictures so 
this could be one that generates the SSB at that frequency, 
hetrodynes it up to 9 mcs (filtering could be done at either 
frequency but most likely at 455) and then mixes with a 5-5.350 
Mcs VFO.   That suggests an earlier -- say 1960 +/- -- design.   
Tidier ideas -- fewer conversions -- were more common later.  

Upconverting from 455 kcs to those two bands to 75-20 will 
generate some spurs.   8 x 455 = 3640, 9 x 455 = 4095.   And 
others, too, depending on details of the conversion scheme.   

I can't think of a way to make that conversion work without having 
to generate both sidebands.   The nicer band imaging designs give 
you LSB on 75 and USB on 20 without having to do that.   For 
example, generate USB at ~5 Mcs and either add that to or 
subtract it from a ~9 Mcs VFO.   Stability is a challenge with that 
one, but it can be done, and it's trivial for VXO-type designs.   

(Anyone here ever build the 'Imp'?   Three tube VXO SSB 
transmitter found in one or two of the SSB For the Radio Amateur 
books?   Someday I'm going to do that with 150 mA tubes, say 
with a 70L7 rectifier/PA or a pair of 35GL6's, and two 17H3's or 
35W4's in a doubler.

(Definitely regressing in my old age.   I use fewer and fewer solid 
state diodes, more and more glass ...)

I'm just nitpicking about the TX design.   This was done at a time 
when ham SSB gear didn't come in a four-color box with a plastic 
handle on the top from Japan and it represents some serious ham 
skills.   Congratulations!

One you get the circuit diagram up we should be able to figure it 
out.

Thanks Walt,

First I need to find someplace capable (Kinkos?) of scanning/copying a 
18x24" document. Fortunately the schematic was tucked into the rig and is 
in quite good shape...all done with one of those little plastic stencils 
and a drafting pencil.

Fun station! I look forward to putting it on the air after a 
checkout.  Will look forward to your comments on the schematic.

Very nice rigs, John. Quite a find and a tribute to someone's skills
....do you know who the builder was ? what does the tag on the front of
the Tx say ? Excellent construction with a completely separate PA cage,
etc. I hope more and more of this type stuff is uncovered in the future.
Must have been a Navy guy based on the paint used.

Go to OFFICE MAX, KINKOS, or a Blueprint place...

They all have the larger-format Xerox machines, capable of enlarging
documents or just running 'em 1=1.

Frequently, I'll take a schematic and enlarge it, so I can pin it on the
wall, while I work on the radio... easier to read, and a great way to make
BIG schematics or just copy odd large sizes.  Typically, they charge by the
square-foot, as the paper is either 36" or 42" wide... (most construction
drawings are 24" x 36" or 36" x 42").

My local Kinko's has the capability of both copying and scanning to disc 
blueprint size documents.  The price is reasonable (I think it was 75 cents sq

HEY!  I thought that was for me!   <G>

I guess my Navy service is the reason I like the gray paint.   It's 
certainly the reason for my enduring affection for one of the biggest 
wastes of government money ever -- the RCA SRR-11, 12, 13 
series of receivers.   A much modified SRR-13 is the only general 
coverage receiver here -- the R-390A's have stayed ahead of my 
price range for three decades now.   

Study the SRR-13 closely and you'll cease to wonder why RCA is 
now a subsidiary of GE.   

I've had to switch to darker grays though -- can't find spray cans of 
the 70's Ford 'dove gray' any more.   The few finished projects 
these days look more Canadian military than U.S. Navy.  

I continue chewing on the General Coverage HBR project.   The 80-
40 meter band imaging receiver (six tubes plus rectifier, half lattice 
crystal filter, push-pull 12AT7 mixer) turned out so well that it 
inspires use as a tunable IF in a set along the lines of the G2DAF 
Mk II.  I will use a ladder filter rather than the 2-crystal half lattice -- 
squarer sides and higher ultimate rejection.

With the IF section needing only the tuning range to be tweeked, 
the project SOUNDS simple, and I'm hoping that at some point it 
will be.   But details remain elusive.   

The plan is to take the 120 crystals of the BC-1335 WW-II portable 
FM set, 5675-8650 kcs (25 kcs spacing) and multiply the 
frequencies x10 to give 120 frequencies 56.75-86.50 Mcs.   
Subtract 49.2 Mcs yielding 7.55-37.30 Mcs by 250 kcs steps.   
Adding a tunable oscillator 1.704-1.454 Mcs to a fixed IF of 4.096 
Mcs (the ladder filter with 4.096 microprocessor clock crystals) 
gives a tunable IF of 5.800-5.550 Mcs.   The difference between 
that and the synthesized band crystal frequency is the tuning 
range for the band:  for the lowest band, it's 7.550 Mcs - 5.550-
5.800 Mcs = 2.0 - 1.75 Mcs.  

The 1st mixer input must be tuned to cover the whole range; I plan 
three ranges, roughly 1.75-5.5-16-32 Mcs.   Each encompasses 
two 'real' ham bands and there'll be two crystal sockets selected 
by the bandswitch for each, plus a single socket on the front panel 
to allow any one other 250 kcs segment to be covered.   The 
bandswitch will be marked 1 A, 1 B, 1 external, 2 A, 2 B, 2 
external, 3 A, 3 B, 3 external.   Extra crystals store in a drawer 
under the receiver cabinet.  I have a nice nearly complete set and 
quite a bit of junk.

Somewhat along the lines of the Collins S-line.   In theory I could 
use an overtone scheme for the crystals but it would have to be 5th 
overtone x2 to get the x10 and using WW-II fundamental crystals 
on 5th overtone and dealing with the displacement of the 5th 
overtone from the 5th harmonic of the marked frequency, 
discouraged me.  Overtones from overtone crystals are fine but 
getting them from fundamental cuts can be tricky, unstable, and 
require slightly oddball tuning settings -- not good for a control 
that's ganged.  

The synthesizer must be tuned; that's another knob and half or 
more the sections on the bandswitch.   I'm hoping to gang only two 
tuned circuits in the synthesizer -- maybe the x10 frequency can 
be generated with a single envelope triode-pentode or an ECO-type 
circuit with the crystal frequency untuned and the plate tuned.   
Then only the x10 - 49.2 Mcs mixer output (7.550-37.30 Mcs) has 
to be ganged with that.  That would be two tuned circuits with three 
coils and a couple of trimmer caps each.   A little messy but not 
too bad.  

This does not sound terribly complex -- an extra mixer plus three 
tubes to generate the crystal mixing frequency.   However more 
plate current is required so I'll use two 17H3 (miniature damper 
diode) rectifiers instead of the 35W4 of the 80-40 design.   A 
crystal calibrator is also needed to align things on each band -- 
another tube.   So six tubes for the IF section, four more in the 
converter section (1st mixer and crystal synthesizer), a calibrator, 
and two rectifiers -- 13 tubes.   

The calibrator will tweek the 49.2 Mcs crystal oscillator.   Tuning 
range may be an issue -- crystal freq. errors of a couple kc are 
common and they are multiplied by ten.

The mechanicals are more challenging than I expected.   A general 
coverage receiver of this type cannot dodge all internal spurs just 
by careful choice of conversion schemes.   I think I have put the 
worst of them outside the six real ham bands but the rest must be 
minimized by filtering (fancy/numerous tuned circuits are not 
popular in a simple home design), by use of balanced mixers 
(complexity takes off) and shielding.  

But better shielding means boxing stuff up, while bandswitching 
three tubes and tuning a total of five air variables (1st mixer input, 
synthesizer, LO, calibrator, and VXO BFO) means some shafting 
must be fitted in.    Then there are the crystal sockets/switching 
that go with the bandswitch.   

Two boxes, both below the chassis:  One housing the 1st mixer 
and calibrator, the other with the LO/2nd mixer.   Boxes take up 
space by forcing space-wasting arrangement of parts.   But they 
stiffen the chassis which is particularly useful for the LO.   With 
thin shims under, the Bud open side boxes will go in a Bud 
chassis of the same nominal height with the flanges level with the 
sides, allowing a single flat bottom plate.

The sheilding also bites on front panel space -- and this is a 
receiver with more than the usual number of knobs.   I had to go to 
a wider chassis (14") with a 16" panel because so much was taken 
up by the LO/2nd mixer box and LO dial that there wasn't enough 
room on the chassis and panel I had planned.

I think the front panel is going to be a bit untidy.   There's just not 
the freedom there that you'd like.

A freebee discovered on the 80-40M design is that you can put 
push-pull mixers driven from a very low impedence mixing 
frequency source on the AGC line without trouble.   (Mixer drive for 
that set is taken across 0.01 mfd caps right into the cathodes.)   

The oscillator must develop a lot of power -- ~80V p-p on the plates 
of the 80-40M design -- but with careful shielding and filtering, 
chassis currents minimized, and in a tight box, it may be okay.   
The LO tunes in the opposite direction from the receiver so it's  
tweets will go by quickly.   

The front end is in another box and push-pull signal feed will also 
be favorable.  And LO harmonics are not in the real ham bands.

(If it has only ever been denominated in mHz, it is not 'real.')   

The 80-40M set is as flat AGC-wise as you could want, and the GC 
one can have both mixers on the line.  This helps the 'working' 
dynamic range even more and simplifies things considerably in an 
IF section using sharp-cutoff tubes and plate detectors.  

There seem not to be any remote or semi-remote cutoff tubes in a 
pentode-triode combination.   I'm using 7HG8's for IF stages and a 
few other jobs.   

There's way too much other stuff going on here; I don't ever work on 
the set in a concentrated way, but I'm still in thinking things 
through mode with parts sitting on the chassis on the kitchen 
counter, so that's not a big loss.   

Huh?  Oh, next to the scope.   Isn't that logical?

Hi All,

Well, FD's over for another year, & VERY casual operating on 80- and 40-meters CW with the 1923 p-p 203A Colpitts self-excited transmitter / Heathkit SB-301 receiver yielded a page --- & then some --- of QSOs...

By far, the most were made on 80-meters. I think the chirpy signal --- coupled to the fact that both the antenna and tank coil were effectively "...wind modulated" by the outdoor environment --- contributed to this. Forty was VERY busy here, and I'm sure 99% of the gang therein were running with extremely tight CW IF filtering, which would have made my chirpy signal essentially undetectable! On 80 --- where things were not nearly as hectic --- it's my supposition that IF filters were relaxed, to hear more (possible) callers in the passband...hence my greater success there.

I had a very FB QSO with Rod Newkirk (former "How's DX?" editor in QST) from his Ottawa QTH, and more than a few of the OT's I worked commented on how well technology from 83 years ago could still sound to-day. The vast majority of to-day's Hams, though, have apparently been spoiled by the superlative and near-universal T-9 quality of signals emanating from to-day's appliances, and when they heard me, more than one hesitated to respond, and instead, elected to scamper down the band a few KHz, or so, to call CQ FD again! 

I guess chirp & character in one's CW emanations are a foregn concept these days to most! Hi Hi

Anyway, if I worked you, thanks for the QSO --- if I didn't, well, maybe next year I'll build up a small oscillator & convert the p-p Colpitts to a p-p RF amplifier in a MOPA set-up, and try it again, but this time WITHOUT all of the "...wind modulation." Hi Hi.

Hope you & your respective groups had fun --- I did!

Message-ID: <002001c699f0$a325c4c0$9e305a45@CompaqS5000>

Hi Gang, 

Maybe this is a tad off topic, however, starting this Thursday --- and continuing right through the coming weekend --- our Industry Canada here has authorized the use of the special prefix "XM3" in place of "VE3", for licensed Hams operating within the village of Newcastle...

This is in celebration of the 150th anniversary of the village's existance.

We have a general population of about 8500 here, with a registered Ham count of 24: I personally mailed-out notices to all 24, and had 4-5 of the letters returned to me by Canada Post! These locals have either moved, become SK's, or otherwise fallen off the face of the earth. It seems the balance of the guys just aren't all that active, either...

I hope to remedy that some, by signing "XM3XZ" for the duration --- all bands, all modes --- from a station set-up outside, in my back yard. If you're a prefix hunter, & you need "XM", have a listen for me! I hope to activate my Heathkit monobanders on 75- and 20-meters SSB, & my Yaesu FT-980 for the other bands + CW/AM...

Today's quiz question is "how many times can the same person 
look at the same numbers and miss a problem?"  

Answer:  A bunch.   

The synthesizer starts with those fundamental crystals 5675-8650 
kcs; after multiplication and subtraction of 49.2 Mcs, the result is 
mixed with the signal from the antenna.   However, I overlooked the 
fact that the lower end of the range of crystal frequencies overlaps 
the tunable IF, 5550-5800 kcs.   So the five bands using crystals 
below 5800 kcs (1.75-3.00 Mcs) would all contain a birdie from the 
frequency of the crystal for that band.   

There will be two or three three tuned circuits to attenuate these 
signals, but they'll be audible.  The band 3.000-3.250 would have a 
band-edge marker at the low end, where the 5800 kcs crystal for 
this band is picked up by the high end of the IF tuning range.  

If you want to look on the positive side, these frequencies supply 
some calibration points for the LO.   Not enough to do the whole 
job though -- they're all at the low end of the band.  So I probably 
can't get away with claiming this was just a clever piece of design 
work.

You could move the band crystal range up 150 kcs to start at 5825 
kcs -- or just skip the lowest frequency crystals in the set and 
change the 49.2 Mcs subtraction frequency to start the coverage 
where you like.  Neither idea was really terribly attractive.  The 
receiver is planned around a set of crystals that I already have. If 
starting with purchased ones, you would go with overtone units 
($20 x 120 = $2400 ... Ah don' think so ...) and avoid the whole 
issue, as well as getting rid of the need to hetrodyne to get the 1st 
mixer frequency.   And I'm too obsessive to really like throwing 
away part of the set.

I also considered moving the tunable IF by moving the LO down 
from 1.454-1.704 Mcs to 1.304-1.554 Mcs, giving an IF 5.400-5.650 
Mcs.   The fourth harmonic of the LO would then cover 5.216-6.216 
Mcs so it would sweep entirely through the tunable IF range, going 
in the same direction.   The LO and 2nd mixer (which gets the 
tunable IF as the input) are in the same box.   This would be a very 
strong spurious signal tuning slowly through the same spot on 
every band -- a definite loser.

Or you could keep the LO range the same but move the fixed IF 
down to somewhere in the upper end of the 75 meter band.  You'd 
have the BFO in a ham band and the least bit of feedback would 
make the IF passband shape go west when tuned near that 
frequency ... The idea was dead before I even looked at available 
clock crystal frequencies.

Obsessive or not, skipping the first six crystals in the set seems 
the best approach.   This means starting with the 5825 kcs 
(channel 276) crystal and changing the subtraction frequency to 
keep the lowest synthesizer output frequency at 7550 kcs so the 
tunable IF remains 5550-5800, This requires an overtone crystal at 
50.7 Mcs, but I have that crystal -- it was used in the PRC-6 handy-
talky.   You lose the coverage above 30.50 Mcs, but that's not a 
big deal.   

The harmonics of the LO (1.454-1.704) also must be considered.  
None of them are in the fixed IF, tunable IF, or the lower ham 
bands but the 9th harmonic goes through the 20M band. It's going 
in the reverse direction (higher LO frequencies -> lower dial 
frequencies) so it'll be going fast.   

Some other (non-ham) bands will be hit by LO harmonics.   Since 
the LO comes after the front end, these harmonics should be close 
to inaudible if the LO/2nd mixer box is closed and well-filtered.   
Also the layout there (and tuning cap design) makes it easy to 
return all the grounds to the tuning cap frame, thus minimizing 
chassis currents.  

With 30 Mcs of total coverage it might seem logical to start lower 
than 1.75 Mcs -- say down at 500 Kcs.   However doing so would 
require tuning the front end range in four rather than three bands 
because it's tough to get more than a 3:1 tuning range with 
conventional tuning caps.  In addition, extending the tuning range 
down would make it overlap the LO range.  You'd pick up another 
(probable) birdie per band from the LO and there could be trouble 
with more complicated spurious responses caused by strong BC 
signals near the LO frequency.  

It could be done on a 'take what you get' basis, just by using the 
six omitted crystals and adding the fourth range to the bandswitch. 
Given the strength of typical BC band signals, that probably would 
be useful.  However the goal was to keep this project fairly easy to 
build.  Adding BC band coverage probably exceeds my level of 
ambition.   

Commercial grade general coverage receivers beat these sorts of 
problems with complexity -- adding or taking away a conversion on 
some bands, for example -- or by making other types of 
compromises such as using single conversion with phase-locked 
oscillator.   In a practical homebrew project, I think it's better to 
accept that there will be some garbage and try to leave it in places 
you won't often visit.  

It's still a paper receiver (plus what I hope is now a complete 
bucket of parts) but I think I'm closing in on the design.
