I recently purchased a new icom
M710 with a tuner. My next inqury is regarding the TNCs or HF modems.
I read quite a bit about ptc IIe from SCS and i guess it can be upgraded to ptc III with firmware and more memory(unless it laready has enough memory). They are usually around $800-$1200 or so.
My question is why is the other modem
like the KAM-XL from kantronics so much cheaper? Like 300-400 for a new one. I guess is it because it doesn't do pactor
II or III.
Also could anyone tell me what data rates are normally achievable. When they say 1200bps is that the speed of the RS232
connection to the laptop
or the speed of the HF connection.
