[ICOM] IC-910H Satellite Work

[John Germanos]

Joe,
I use the Icom 910H for satellite communications. What you are doing is the 
best that you can expect from the radio.
The use of external preamps (like the Icom preamps) are very helpful, but 
not necessary.

It is difficult to keep up with Doppler when working the LEO satellites. I 
finally bought SatPC32 from Amsat. With this program, a serial port (comm 
port), an Icom CT-17 or equivalent aftermarket interface, working the birds 
has become as easy as working your local repeaters.

If you have an AZ-EL rotor such as the yaesu 5400 or 5500 and an interface 
for connection to a second com port, (I use the W0LMD Sat. Junior Interface) 
this program will also steer the antennas.
If you don't, that's OK as well. I know many satellite uses who operate very 
successfully without AZ-EL capable antenna systems. My friend uses 
egg-beaters and preamps as does a great job.

Rule of thumb, with radio in sat. mode (full duplex) with separate antennas 
for 2 and 70cm, If you here yourself, then most others will here you.

Good luck, the 910H is overall a great radio for sat. operations.
