Let's go step by step

3db down now: 1,60V RMS 51mW

Same signals on my monitor and some drop on F5WK and EA5CV reports

Hi Graham, MF
 
Yes. The efficiency of this antenna setup is really outstanding  :-O
I can clearly see the signal on my monitor waterfall at 7Km when injecting -33dBm
 
Just at sunset between EA and DL I got two WSPR decodes from DH5RAE and DJ0ABR

I have the 3dB atenuator ready to be installed. Will do it when I get home in a couple of hours
and will change the WSPR tx power indicator and Opera info to notice the change

Luis, I switched my radio off last night at about 23:30 utc.
I will leave it running opera all night tonight if you want to try different power levels again.
