I've been contacted by someone wanting to build an HBR-14 and
he wants the chassis and front panel drilling templates. Does anyone
have a copy they could send me to add to the file. I've got the ones
for the other receivers but not the 14.

Hi, all concerned:

Looks like the other guy eat me out for $5 on that "HBR16" or HBR12 or what
ever it was on ebay.   Oh, well.   Serves me right for going to sleep at a
reasonable hour.

In any case, I won the "matching" c-w transmitter auction, and I'd like to
get a receiver to keep it company, if I can afford it.

If anybody wants to sell his finished-or-not HBRxx, send me some info,
pictures, and asking-price, privately, please.

Yeh, I started and stopped one in 1958 or 1959, and am suddenly nostalgic
for some hollow-state technology again ;o).

TIA and 73,

This is the HBR-11 I was talking about. It works with the 40m coils
(shown installed). Lots of sensitivity. There is also a set of 80m coils,

but they haven't been tweaked. All the coils are wound on pill bottles
and there are several spares. The construction looks pretty good, the 
front panel is nicely finished and labeled. Uses the Eddystone 598 dial 
which is very smooth and described in the article. There is no enclosure.
I have no history on the unit and neither does Cliff. He bought it at 
Dayton several years ago.

Pictures are at   http://www.qsl.net/k5bcq/pics/

Cliff would like to get $150 for the unit. Shipping is extra, whatever
UPS or FedEx charges, and I'll do the packing/shipping. 

To make this as fair as I can, it's $150 plus shipping anywhere in the
world. If there is more than one person interested, I'll note the names 
and have my wife draw one next Saturday. This will allow those
not on-line and leisurely enjoying the holidays to participate.

Feel free to ask any questions.

Additional comment......

The small red/brown areas on the bottom of the aluminum chassis
are rust residue. Guess they had it sitting on a wet metal shelf
at one time. Minor problem in my mind, can be easily cleaned.
Note that the chassis has the triangular gussets installed on the 
bottom ...very good !!  Stiffens it up considerably.

Next question..........

One source for a pretty good dial is an old tube type stereo 
receiver at a garage sale or Goodwill store, or ? the cord dial
mechanism can be used if you have the room. In fact, I figured
out the small Heathkit transceiver pulley on the cap will give 
you a 7" travel.

Or make a drum out of an ARC-5 transmitter output coil ...you 
can probably use the window too. I think I have one.

Hi,

I have a cardboard box containing some large diameter dial cord drums (must 
be 2-3" dia.) and with std. 1/4" hubs. Let know if I can help. (And if a 
tiny bit of machining should be req'd., I might be persuaded to help out 
with it as well.)

I'm just completing a home-brewed slide rule dial mechanism retrofitted 
onto my HBR-16 as I got tired of torqueing the old 180-degree National MCN 
I installed ca. 1960.

Do you mean dial pulleys? I have a few, of various sizes.

Dial drums (as I've heard the term) are short wide cylinders that carry the 
dial calibration on the edge. The HBR website has pictures of a receiver I 
built that used an old plastic cereal bowl for a dial drum.

Hi, All:

SOme time ago I started gathering parts for an HBR receiver of some kind.
I ended up with a "modified" HB-65 ( 1965 ARRL Handbook ) that is in the
"first picture stage", by now. The components are mounted on the chassis but
not wired yet.
The circuit was changing and evolving as I was finding components. The ideal
was an HBR 11 or 13 but the cabinet that I found could only accept a 8 by
12" chassis, the power transformer yields only 65mAmps, so I am limited to a
7 tubes, HBR-7 ??? :-)  ).
The Bands to cover are 40 and 80 without bandswitches.
The only ( so far) mod to the original HB-65 is the mixer. Instead of using
a 7360 I am using the 6U8A pentode and the triode will be the HFO.
I spoiled a couple of 262Khz I.F. transformers (Miller K-Tran 15-H) while
moving the windings apart as Kees suggests in his fine notes but now I have
four good transformers ready to shunt with 430pf to resonate at 100Khz.
For the first IF I found two Miller 1732.
The only thing that I'll have to experiment with is the BFO coil. I am
thinking on using one side of another K-Tran 262Khz transformer in a
colpitts oscillator circuit and get to 100Khz with added capacitance.
Has anyone tried this?
Also since the IF is 1700, the front end has two tuned circuits (band image)
calling for Miller adjustable coils (4406). How about T-68-2 toroids? What
is the issue (other than non-adjustable cores) with using iron powder
toroids with tubes?

In the next days I'll take some pictures ( as soon I can borrow a digital
camera), and post them.

Thank you in advance for all and any feedback.

The 'issue' with torroids is a non-issue -- torroids became cheap and 
common just after vacuum tubes began seriously phasing out, and 
since bipolar transistors are crummy receiver devices (very limited 
dynamic range), high-Q coils were absolutely essential.  In addition, 
torroids are smaller for a given inductance and Q and they are self-
shielding.  With all that going for them they swept the field.

Torroids work very well indeed in vacuum tube circuits -- the HBR2K 
project is a vacuum tube receiver following the conversion scheme 
(and using the chassis and key parts from) the FT-101 and torroids 
have been very helpful.

Solenoid coils are 'more vintage' and they may be easier to make.   
By using a tuning slug you can easily make the inductance 
adjustable.   An air core solenoid on the right form is more easily 
made temperature stable, so a better choice for a critical VFO like 
that in your HB-65, which, since it will tune about 5200-5800 Kcs, 
needs careful attention if you are to be able to receive SSB without 
your hand on the tuning knob.   Other than those considerations, 
solenoids are not in general as good as torroids in receiver circuits.

The only thing that might be an issue is the change of mixers.   A 
6U8 will certainly work as a mixer but has much lower gain than a 
7360 or other beam deflection tube.  Looking at the HB-65 diagram, 
you have two mixers, one IF stage of modest gain (6BA6), a no-gain 
2nd detector (solid state diodes) and a moderate gain AF amp.   
That's probably not really enough gain if using a pentode instead of a 
beam deflection 1st mixer -- you may not have enough volume or 
decent AGC action.  I'd consider using a 6BA6 RF stage between 
the two front end coils -- the circuit can be found in almost any of the 
common receiver designs.   If genuinely tight on plate milliamperes, 
go to a 6BJ6 in both RF and IF sockets.   

A second issue is that a beam deflection tube provides better 
isolation between the VFO and the signal path than does a pentode.  
You might want to consider using a 6C4 as the VFO and making the 
triode of the 6U8 1st mixer into a buffer.   Otherwise, voice signal 
peaks will tend to pull the oscillator off frequency and cause 
distortion.   

Finally, if moving IF transformer coils apart is needed and not easy to 
do, you can get the same effect by adding one or more shorted turns 
between them.   Just put a barely long enough loop of hookup wire in 
the space between the coils and solder the ends together.  If that 
doesn't lessen the coupling enough (it usually will) you can add 
another *separate* shorted turn.

The HBR2K project has been shelved the last few weeks due to 
outside work, a family wedding, and other such trivial non-homebrew 
activities;  I'll be back to it shortly.
