No problem Fausto. USB or LSB ?? ... :-)))))

You will be the first Italian station, don't worry. This would not be possible without your help

This weekend I´m out of QTH again. Left the WSPR running at full power and geting again

reports from DH5RAE and DJ0ABR in daylight

I made another test with the signal generator of SHAR110 antenna analyzer

Injecting -33dBm (5mV level) to the antenna I can see the signal on my monitor at 7Km !!!

Next step is -43dBm (2mV) and there is no signal visible in waterfall

Go figure ..... :-O

Hi MF

Tonight I went back to QRP

Not a PA failure. Just wanted to test the good efficiency of the antenna with low power

Transmitting directly with U3 with something like 500mW even got one spots from EB3FRN

and one from F5OWL but vey hard

Using the small PA could range the output from 2 to 5W adjusting voltage

It has been working with 5W all night. My WSPR Tx showing power 0.05W 17dBm

Got reports from 38 stations, some >3000Km in Scandinavia

I wonder which is the ERP on this antenna for only 5W excitation !
