How much power are you planning on running? On RS-44 I use a foot switch to disable the speaker when transmitting so as to not great back ground noise. Mike On Sunday, August 11, 2024 at 04:29:22 PM EDT, JOHN GEIGER via AMSAT-BB amsat-bb@amsat.org wrote:

WIll most 2 meter amplifiers pass a UHF signal on receive when the amp is on?  I am wondering about using a 2 meter amplifier for Mode J satellites, where you transmit on 2m and receive on 70cm.  Will the filtering in most amps severely degrade the receive signal on UHF?
