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 !
