Initially signals on the band were good (Gary G4WGT was a nice readable signal up here) and after initial reports at normal powers I reduced TX power to : 10W 1W 500mW 250mW 100mW 50mW At each level down to 100mW Finbar was able to copy some or all of what I sent and at 50mW he was able to detect snatches of long dashes. ERP was obviously much below 100mW for all these tests, as my normal TX power is just sufficient to drive my very short antenna to the current needed for estimated 100mW ERP. I returned power to normal but unstability in propagation started, deep QSB and some QRN, so we forgo the re-run of the previous night's QRPp from GI. We were able to hold (despite the varying signals) a QSO for over 1 hour unitl just after midnight localtime. Each of us also called CQ during the QSO to see if any other stations were interested in reports etc, but nothing was heard. I received email confrimation that my signals were heard my Mike G3YPE in Homfirth, W.Yorks and by Mike G3GMS near Cullercoats in Northumberland. Obviously both stations had no difficulty hearing Finbar! We intend to try again tonight, 11pm local time. If anyone knows of website where daily records of geomagnetic / solar data can be retrieve I'd be grateful. I want to start noting the salient data alongside my notes etc. in case I can spot any correlation between the signal quality and the various measures of likely propagation (SFI/A/K/SSN etc) Regards, John GM4SLV
