[Hallicrafters] New Guy & HT-37

[Karin Johnson]

I did a search for HT-37 and QSK and came up with a link to a file on the
BAMA site.
After looking at that link schematic it appears that this mod incorporates
the circuit
from the HT-32B into the HT-37.  In my opinion it does not really provide a
full QSK 
type of operation. YMMV.
I designed and laid out a PCB for a true QSK for my HT-32B based upon an old
QSK 
article for a Collins S-Line years ago.  My design uses an external vacuum
relay and
has circuitry to set up the timing so the transmitter does not "HOT KEY" the
relay.
It requires a bit of modification, although not complicated, to the HT-32B.
So for 
the purist this may not be acceptable, but the modifications can be easily
retrofitted.
I'm not in the business of selling these things but if you're interested I
can you an 
Extra board I have plus a BOM.  I was considering doing a newer version to
make it easier
to install and retrofit, but never got around to doing this due to other
priorities.
