[Drake] Drake 2-B as Selective Demodulator

[Transmaster]

I just checked up on the Drake 2B and it does have a product detector.
This is getting interesting.  If this conversion works out this is
going to make a bunch of R390 types happy.  It is to bad there isn't a
simple way of fixing the radio so the IF frequency could be adjusted
for other frequencies it could be used on a whole bunch of older
receivers such as my Collin 51J3 which is my absolute favorite
receiver.
