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 !

Hi Luis,
Sorry, forgot to read your email completely.

That was a BINGO Markus !
Next step is to accurately measure RF current. May be I'm well over 1W ERP ....
What is the limit in EA? Do you know it at all? :-)
Thank you to all you guys to help me achieve this :-)
Ops ! CW QSOs .... Yes, I can do some CW but need refreshing it a little. We will make many FIRST as there has been some EA activity
before on MF but not sure if they worked many countries. Workload at job pressing this days and a trip to Mexico at the end of this month
RR. Tell me when you can find the time to try.
73, Stefan
Keep tuned ;-)
