Remember, although the downlink from UO-22 is hard to receive, the UPLINK is just as easy as ISS, or PCsat but at 9600 baud. And every mobile Kenwood APRS D700 or HT, D7 has 9600 built in... Thus, it is an ideal mobile/HT communications satellite... But we need more users or its just the sound of one-hand-clapping... > Remember, although the downlink from UO-22 is hard to receive, the > UPLINK is just as easy as ISS, or PCsat but at 9600 baud. I should have said, that uplink is almost 20 dB easier than the downlink if you are running a 50w mobile. or 10 dB better to your HT... So do not be discouraged by the weak downlink if all you need to do is send an Email while mobile in the boonies.. > And every mobile Kenwood APRS D700 or HT, D7 has 9600 built in... > Thus, it is an ideal mobile/HT communications satellite...
