When you made 2 contact already you did Perfect. With a capital P.

People will respond with how to handle doppler, but reality is that it can be difficult, even when you have an automated setup.

Keep going, you're doing just fine!

Hi all,

I have just tried working through AO73, with limited success. I need some
very basic help with satellite operation.

I have an IC-9100, I set the uplink and downlink to mid-range (435.140Mhz
and 145.960Mhz), then call CQ until I hear my own signal

which has worked every time, then I get problems.

When someone calls me back I panic, what do I do when the doppler kicks in,
do I move both TX and Rx, or do I just move my Rx to follow the other guy.

I haven't managed to get SatPC32 controlling my rig yet, also, I want to
learn the hard way - manually.

Can someone point me to an article that explains in detail how to operate.

I know this is a very basic question, but we all have to start somewhere. I
have managed tow contacts so far. First was AO73 and tonight with FO29.

Not sure how I did it, but thanks to ON5NY and EM5SR.

Happy New Year
