Subject: [HBR] Under construction HBR-?? -- And the G3RKK Delemma.
In-Reply-To: <01cd01c42ef4$6cb118e0$6500a8c0@BILLDESKTOP>
Message-ID: <4092BE17.18717.EBACFA@localhost>

Bill, that's going to be a nice project; you're an inspiration to us all!

As mentioned in my last, I have a G3RKK receiver (see the 4th ed. 
RSGB book) that I bought as a result of a listing here by Byron 
Tatum of Texas.   Both of us thought at first that it was a G2DAF 
job but its the (probably rarer) UK bandswitching version of W6TC's 
work.

My first take was "it's original -- let it be."    

Then I looked at the wiring job and thought "It's a mess, but maybe 
can be re-kitted."   

Since then, I've realized that this unit wasn't built with new parts to 
start with.   Sure enough, the big stuff is all original UK parts -- the 
power transformer is the tall-stack unit you see in the original, it 
has the beautiful Eddystone 898 dial, all those Electroniques IFTs; 
even the Electroniques bandswitching front end.  

But the whole works is built on a badly done steel chassis and all 
the small parts are this-side-of-the-pond makes, evidently salvaged 
from a few old BC sets. (Some were *unfamiliar* makes -- that's 
why I thought they were U.K.)   

Now I've done a bit of that myself -- I usually use at least some 
small parts from a previous project.  (Wouldn't surprise me to find 
that a few of the more durable items have been circulating since I 
was a teenager, back when RCA was right proud of the 6146!)   But 
this thing's a mess, even the wiring's a bit o'this and a bit o'that, 
and because the small parts weren't good quality to start with, I 
can't look forward to trying to simply repair it stage by stage.   At 
some point you're talking about 'jacking up the hood ornament and 
driving a new car under.'    

Rather than go there, I think I'll strip it, clean up the chassis work, 
repaint, and start again, using the major parts.   It can become a 
good looking unit with no more than a file and some paint; I'm 
pretty sure of that.

The other possible angle would be to use the dial and few other 
major items and go straight for a G2DAF.   Since that's a tunable 
1st IF rather than a conventional bandswitching/tunable front end, 
it's a major design change; some good stuff would be left over (and 
some would have to be acquired)  and there'd be a major overlap 
with the design of the General Coverage HBR, already (very 
slooooo-ly) under construction.

I'll probably re-kit with all new small stuff.  My wife will be out of 
town for 10 days in early May; while that doesn't give me more time 
it does mean more control of the time I have and if the weather's 
suitable for painting, maybe ...

My first thought was that this set must have been built in the U.K. 
shipped back as a re-kit and rebuilt with local small parts.  But 
looking more closely a few minutes ago, I discovered a label on the 
back of the front end assembly with 'Canada' on it.  So I'm 
guessing it was built there.   There may be a few more clues when 
it's disassembled -- there's more stuff on that label that will be 
visible when the front end is out of the chassis.

TOO COOL!!

Nice job from what I can see. The "aluminum tray" dial thing is neat - I 
would have submounted the tuning cap and cut a window in the front panel, which 
makes calibrating the dial a much bigger job than your way. 

Two questions:

- is the tray deep enough for pilot lights so yiu can have an illuminated 
dial?

- how did you adapt the BC-453 tuning spline to the knob? Looks like 1/4" 
shaft to me.

Message-ID: <001801c43102$2ec4edd0$6500a8c0@BILLDESKTOP>

Listers,

Thanks for the kind comments on the HBR-??. I have a few more comments =
along with the pix at www.lizcurtishiggs.com/images/special/hbrpix.htm.

Specific answers to questions: There is probably room in the "pan" for a =
grain of wheat type pilot light; I haven't decided whether or not to do =
this yet. The space is about 3/8" once you take off for the thickness of =
the pan. My concern was for heat buildup. Not shown in the pictures is a =
plastic window with a hairline cursor salvaged from unknown surplus =
equipment (the date stamp was 1945). This early stuff is not very =
resistant to heat, as many users of surplus equipment will tell you. If =
I do put  bulbs in it, I'll probably put a series resistor in to lower =
the heat.

The connection to the spline was made through a standard solid 1/4 inch =
shaft coupler with a shim insert made by wrapping a piece of tin plate =
around a 3/16 drill bit. Not a perfect fit, but close enough that the =
offset of the knob is not noticeable. as the shaft length is only an =
inch or so, no wobble is apparent.=20

The tin was cut from a shield plate salvaged from a defunct VCR circuit =
board. By the way, I plan to use pieces of the same stuff to shield =
across tube sockets, as it is quite solderable and easy to work with and =
can be cut with snips or heavy scissors. If you do this, round off the =
edges, as they can be razor sharp; learn from my unhappy experience!

73 and happy HBRing!=20

I have found among my collection of older QST's a duplicate of the Oct 65

Those of us who are still working probably think retirement brings a 
chance for much more radio ...    Be forewarned -- it can instead be 
just a new job you can do from home but for which you don't get 
paid.   In my case, retirement has been stolen by animal rights 
fanatics and the sometimes well-meaning naive folks who support 
them ... people who seriously want to make it impossible to breed 
or even own pets or any other sort of animal.   Sharyn and I are up 
to here in the nationwide fight to see that our kids and their kids 
will still be able to own dogs and cats, hunt, fish, and the rest.   

She just relayed from a friend that there are AR bills pending in 32 
state legislatures at the moment.   You thought HSUS was 
'respectable' and PETA 'cute'?   Naw ... they got my retirement and 
I'm *not* happy about it.

In spare moments I still think about radio projects -- maybe next 
winter when the outdoor work slows down?  

The recommendation -- at least to anyone who expects to do more 
than build an existing design -- is to find yourself a copy of G. R. B. 
Thornley (G2DAF)'s 'Communication Receivers.'   This is *head and 
shoulders* above anything else I've read on the subject of ham 
receiver design and construction practice.   The material was 
printed first as a series of seven articles in the R.S.G.B. Bulletin, 
July-November 1960 and March-April 1961.   It was reprinted by the 
R.S.G.B. as one of their publications at a later date.

I think I have an original of the G2DAF receiver articles. It's a more of a
booklet or a magazine than a book but it is dedicated to that receiver. If
someone is interested I could probably scan it and put it on line. 

I'm preparing for a mission trip to Vietnam right now but if those
interested aren't in a great rush, I should have time to mess with it when I
return.

I think that would be wonderful.   This is 24 pages of the best 
vacuum tube receiver design info I've ever read, followed by 12 
pages describing the G2DAF Mk I receiver; the person who copied 
my book added the description of the Mk II from the RSGB 
Handbook, as well.   Very clear, very practical information.  Surely 
if the RSGB has none available and no plans to reprint (40 years 
old ... kind of a niche market, I'd say!)  you ought to be able to get 
permission.   

Mine is not an original so not ideal as a source for copies.  
Probably if we keep an eye on eBay and other sources we can turn 
one up within a few months -- or maybe someone on the list has an 
original?

What the heck are they pulling up your way?
I've had no problem with hunting/fishing in GA and HI.
They are worried about raising work animals?
They should be in Atlanta looking at the 'bush meat' trade.
In Atlanta, I can buy smoked monkey from Africa!

I can also buy live turtle and armadillo for dinner, legally (which I have
no problem with as there is no shortage of either)
