Almost all "beacon", WSPR, QRSS transmissions have been near the band edges, leaving the centre of the band for CW QSO's. So far I have noticed only one station that is regulary monopolizing the band by transmitting "lazy men's CW" in the band centre, with a S9 signal. 73, Rik ON7YD - OR7T Quoting mal hamilton : > NO WE DO NOT WANT THE 3 KHZ AVAILABLE ON 500 SWAMPED WITH UNATTENDED > BEACONS TO THE DETRIMENT OF THOSE IN REAL TIME QSO'S > You are not doing anything that cannot be done on CW or qrs cw, which > takes up a lot less bandwidth. > There is plenty of spectrum space available on the other MF band ie 160 > metres for your experiments. > Sri Jim but the beacon business is getting out of hand, especially > unattended.
