Re: 2 meter amplifier on satellites

      How about a dual band amp? Haven’t looked in ages but they used to be
around!

The old Mirage B1016 I have sometimes used on Mode J attenuates 70cm
signals. The amp’s antenna port is permanently connected to a low pass
filter. I am guessing most 2m amps are similar, but only a guess.

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

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?
