[HBR] What would W6TC do?

Hi Walt,
You got something started there. Some of the ideas fit right in with my
own ideas about how I would change it. But I don't really want to change
the basic design very much. I might have to substitute some of the parts
and materials for whatever is available. I'm one of the people who asked
about changes and my most significant change is the form factor or
general shape of the receiver.
Somebody mentioned that the plug-in coils were used to make the radio
smaller (among other things). I would add offloading the power supply
and audio section. I don't know that I would want to use toroids unless
I build a second (or third or...) one so that I have something to
compare. That might be interesting.
Another suggestion was to make the HBR as a single band receiver. Um...
with a set of coils plugged in it is already a single band receiver in
my view. I would more than likely want to make "other" coil sets and I
would probably start with something like the WARC bands.
Plugging/unplugging coils is not a detraction to me. Keeping the plug-in
coils makes it as easy as any other single band radio <g>. Maybe a
converter would apropos for use on the VHF/UHF bands.
I'm not interested in any kind of digital electronic display for a
receiver like that. Digital circuits equate to the radio screaming in
its own ear! Yes I now. All the new rigs are loaded with digital
circuits. Yes I know. Their owners seem to hear other hams okay. I also
know I have worked stations those other hams couldn't hear and I think
mostly due to my lack of digital chips screaming inside my radio. It's
certainly not due to my superior antenna! I prefer filtering and
bypassing by *distance*. By the way...I do have digital gear here but I
turn it off during radio ops.
I know it's heresy but some people mentioned um.. solid state circuits
in an HBR. <casting eyes down - kicking sand with toe>. After a real HBR
is available for comparison something like that might be interesting,
too.
