I came to the shack at 05:15 UTC to find the regular beaconing had stopped running. Apparently if a signal is received the software stops any beacon (to avoid causing QRM) and in this instance it didn't restart the beacon timer afterwards - therefore my log shows that at 23:34 UTC there was a (not correctly decoded) RX frame, and after that no further beacons were sent. Sorry. WSPR would seem to be the mode for finding an opening, not ROS, I won't be using it again in anger. I find as a QSO mode it is very ponderous, which I can accept for the ability to resolve signals deep in the noise, inaudible even, but it didn't seem to perform very well in the presence of lightning QRN - requiring signals to be audible before it decoded them. On top of that I find the actual software to be very difficult to drive. As Mal pointed out, the continuous appearance if spots & information of activity on every other band is very annoying, and seemingly can't be turned off. The Beacon functionality is seriously flawed for the use we put it to. The secret nature of the modem means no one else can integrate ROS into existing (more user friendly) software (fldigi, multipsk etc). The PSKreporter spot-collecting website, while a laudable project, is no way as usable as the WSPRNet online database, which makes finding and tabulating reception reports more difficult. I'll stick with WSPR for beaconing, which is what it was intended for, and look into other MFSK modes for QSOs. Anyone interested in some MFSK-4 tests over the weekend? Cheers, John GM4SLV
