Question 1. Is there ant reason why I can't transmit a modulated carrier (FM) on the 145.900Mhz uplink of AO-16 and receive CW on the SSB/CW? downlink of 437.026Mhz ??.
Technically, yes it would work. But AO-16 is currently designated for voice operations, and CW mixed in with the voice users might get you some nastygrams from the other users.
Question 2. I am 'TOTALLY' blocked by mountains re: the ISS and PCSAT and do *NOT* have 9600bps gear for AO-51 ... however, I can receive AO-16. Can I use the UPW - (PSK modulation) - program to transmit APRS data on the uplink and will that be received on the USB downlink ?? ... and be forwarded to the internet via an APRS station ??. I have attached the UPW file for perusal by anybody who has a few more braincells than LA2QAA and is able to advise.
Pretty much the same answer as #1. Before the memory system crashed, you could digipeat through AO-16. Since then, we are limited to a bent-pipe setup best suited for voice. We may get to the point with IO-26 where digipeating is enabled.
You could try PCsat for 1200 baud APRS, or use MixW and your computer soundcard for 9600 baud on GO-32.
