Re: AO-40 Test 05/08 (long)



If the radio has an accessory outlet that includes a signal to activate an
amplifier on transmit you can use it to drive a relay and run the transmit
signal through an attenuator. This works well on my IC-821H where it inserts
a 30 dB attenuator on transmit so that the transverter is not overdriven.
