Re: LF: OPERA on 500kHz

Yes Roger

I said to you in an e-mail reply, shortly after switching on the QRPp TX that I didn't hold out much hope due to the Top Hat loading on the inv.L being absent.
I might add that this self same little TX prior to my modding for A1A has spent several weeks on the self same antenna unannounced, running 24/7 FSK QRS3 and QRS10 on 500kHz with not a single report.

This compares with my QRPp experience on 30MHz. There is a network (well a small cobweb) of dedicated QRSS group members with full and part time Grabbers avidly looking for QRSS signals on 10meters. My QRPp TX has been running for several YEARS with not a single report. YET the self same TX QSY's a few kHz to send WSPR every 10 minutes and brings in daily worldwide reports.

This is practical experience, everyone must draw their own conclusion, I am saying nothing.

Overnight another report adding 6km to the distance record. :-)

Running rather less than 200uW ERP on 500kHz OPERA4 tonight from a QRPp TX using my usual tiny BFY50 plus complementary PNP PA stage. Continuos transmission with 12 WPM Morse ident between the Opera chorus.
Results are outstripping the recent 2 weeks I spent running WSPR on the band with only G3XIZ reporting.
5P1JYA on RX is a mystery.
