... my dcd lite is blinking steady while nothin showing on the screen. I do know when the sat comes the dcd lite should stay on.
For GO32, I think this is not necessarily the case. Unlike many of the other PACSATS, If GO-32 does not have any trafffic, it drops its downlink. So the DCD may come and go. But it is easy to hear...
Actually this is a great advantage for APRS operations, because this makes a significant downlink delay. This allows those mobile operators transmitting on the uplink actually see their own downlink. On ECHO, there is no delay, because the downlink is always up, and so a mobile cannot turn its half-duplex TNC arround fast enough to see its own packet digipeated.
