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

 

2015-11-30 16:00	EA5DOM	0.475608	-29	0	IM98wn	0.05	DJ0ABR	JN68nt	1556	39
2015-11-30 16:00	EA5DOM	0.475614	-22	0	IM98wn	0.05	EA5CV	IM98ol	59	261
2015-11-30 16:00	EA5DOM	0.475607	-31	0	IM98wn	0.05	DH5RAE	JN68qv	1576	39

 

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

Thank you Tony

Thank you for keeping your monitor working

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.
