I have proscan attached to a Uniden sds200 in Com mode. This connection is successful and I can control the radio. I have created favorites and want to write them to the scanner. But the "write to scanner" dialog has an empty scanner list and does not show the sds200. Pressing the REFRESH button does not help. What could be wrong here? I cannot write to the scanner if I cannot select it from the list. How do I get my scanner to show up on the list?
