Using the telnet packet cluster and clicking on a dx spot results in immediate entry of the callsign into the QSO Window but not the frequency. There is a 5 minute latency for the radio's frequency to change and the frequency to appear in the QSO Window. No idea why this is occurring.
Located the problem. The default polling rate is 500. Changed it to 1000 and now it works quickly and efficiently. Will do some experimentation with other rates.
