[amsat-bb] New operator on uplink power

[Mike Wilhelm]

Hello,
I'd like to get involved with satellite work and haven't gotten on the air
yet.  After reading the recent messages about being careful with power,
I've been tempted to set up my IC-9700 with a pair of coax switches and an
attenuator, so that I can get some attenuation on transmit and straight
thru on receive.  That way I would have more control over how low I could
reduce Tx power.  Any thoughts?
73!
