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? Ted KX4OM |

Ted KX4OM 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 http://www.radioadv.com/ham_radio_eq...ries/BK175.htm w9gb |
