Welll,
A long time ago I tried the DowKey route, After
experiencing the "Zorch" phenomenon, I went to the
E.F. Johnson TR switch. Mainly for the power handling
capabilities, but also for the small amount of amplification
to the receiver, when in receive mode, the TRswitch RX
output is around 150 - 300 ohms which goes well with the
input on the HQ-129(X).
There is 115VAC available (on the E model modulator deck)
however it will require splicing into the lines. Also be careful
of the sequencing, especially with the R-390(*) receiver.
YMMV

All you BC-610 gurus, please, put on your thinking caps. Where is the
BEST place to derive 117 vac for a Dow Key relay? My "E" model came
equipped with a Dow Key relay attached to the back all wired in.
However, it's not an ideal set up. It seems there is always enough
voltage running through the coil to make the relay hum a little. The
main problem is it sometimes doesn't release good and switch the antenna
back to the receiver due this voltage. I haven't traced it to see
exactly where this connection is made, but I know there has to be a
better point. Before I start digging through this heavy monster
(remember the "E" is NOT very friendly when it comes to repair or
servicing) I thought I'd get some ideas from those who have already made
this connection.
Thanks,
Rick/K5IZ
