As promised, I did a little experimenting with the RMS Winmor server software and its busy detect feature. Tonight N0OE was calling CQ right on "my" frequency , within 100 hz of my center frequency. At the same time a Winmor station issued a connect request to my station K3UK-5, in fact this happened twice during N0OE's CQ in CW on 7103. On each occasion my station "blocked" the connect request and refused to respond to the Winmor station calling me. So, as the client software RMS Express works well with Busy Detect, I can report the server sofware busy detects also works as advertised.
