"It's easy" followed by "use any AX.25 1200 baud packet system" makes sense to you experienced hams, but that covers a lot of new ground for me.
Right now, my only transmitter is an HT. I have successfully built at least one antenna for it for handheld use. I have not been particularly successful in using fldigi to talk to it.
I think to follow your instructions, I would need a chain something like this:
computer with ax.25 software <-> fldigi <-> HT <-> some unknown antenna
Does that sound reasonable? I assume the stock antenna will be basically worthless here, is there a suggestion about what I should use? Something non-tracking would be ideal.
Hi David,
fldigi doesn't do 1200 baud AFSK, which is the modulation that you need for the ISS and other APRS satellites. I recommend direwolf.
