Boatanchor TR Switching
 

The 2003 ARRL Handbook shows a design by NC6A for sequenced switching
of a transverter. I have an HT-40 and SX-140 with manual
Standby/Transmit control by one from the other. Looks like the NC6A
circuit (Chapter 22) should work for variable hang-time pseudo-QSK
keying.

Comments?

Look further in that same Handbook (Chapter 22?) and you should find the
Radio Adventures "Vintage Radio T/R Adapter" ... perfect for your transmit /
receive pair

Will do. Back to the library, unless the 2005 Handbook I hoping for
on the 25th has it!
