[AMRadio] TS430 as VFO

Hello Jack:  My TS-430 works OK as a VFO. You should make a 5 to 10 Watt
attenuator to insure that the output is terminated correctly. A better way is
to use the "Transverter" jack (socket) on the back of the 430. The  
output level
is only 50 mW and is 50 Ohms. The transverter output may not drive your
transmitter without using say a 1:9 autotransformer or L network between the
transverter out and the Tx input. Older tube rigs have "Hi Z" crystal input
around 47 K or so and you need to match that somehow. At least with the
attenuator method you will have no trouble getting the required 5-7 V RMS for
the transmitter input.

Good luck and be sure you are in CW mode (no Mics!!)

73, Charlie,  K0NG
