At the peaks of the fades, all 3 modes decode quite well:- MSK4: CQ CQ CQ de g0nbd g0nbd g0nbd CQ CQ CQ de g0nbd g0nbd g0nbd qsl g0nbd@hotmail.com g0nbd@hotmail.com ThrobX 2: CQ CQ CQ DE G0NBD G0NBD G0NBD CQ CQ CQ DE G0NBD G0NBD G0NBD QSL G0NBD@HOTMAIL.COM G0NBD@HOTMAIL.CO PSK31: e C CQ 1Q d0nbd g0nbd g0nbd CQ CQ CQ de g0nbd g0nbd g0nbd qsl nbd@hotmail.aom g0nbd@hotmail.com When the signal levels are down, MSK4 seems most robust, with Throb somewhere in the middle:- t¹8n° ND CQ CQ CQ de g0nbd g0nbd g0nbd CQ CQ CQ de g0nbd g0nbd g0nbd qsl g0nbd@hotmail.com g0nbd@hotmail.com 3-LNBD G0NBD G0NBD CQ CQ CQ DE G0NBD G0NBD G0NBD QSL G0NBD@HOTMAIL.COM G0NBD@HOTMAIL.COM CQ CQ d g0nId g0e d g0nbd iQ CQ CQ de g0p p .0Êwg eet g tloTail.° Watching the decodes, I am seeing that PSK31 is vulnerable to static crashes - each loud burst of QRN corrupts a few characters, while the other modes seem to tolerate this better. This is similar to previous experience. When the QRN is not present, the PSK31 is nearly as good as the other modes. Cheers, Jim Moritz 73 de M0BMU
