Thread-topic: LF: EA5DOM back to MF, but QRP at the moment
Well. Looks hard to believe but from my WSPR decodes I changed the power value to 0.05w
in the WSPR frame when Txing 20dBm. And the first frame transmitted was

2015-11-29 19:12   EA5DOM   0.475607   +5   0   IM98wn   0.05   EA5DOM-1   IM98xn   7   90

Then from 19:14 to 19:22 the Opera8 frame at 20dBm took place. That matchs with my own decode

19:22    477 EA5DOM de EA5DOM Op8 7 km -1 dB F:1%_End in Albir 1519,0 Hz

So R6LDD decoded Deep Search 2 minutes earlier than expected or may be he has not a synchronized PC clock
May be even he could not get the full frame. No fade info in the spot. But he spotted before my own spot !!

19:21    477 EA5DOM de R6LDD Op8 Deep Search ?? 3185 km -37 dB in NOVOROSSIYSK 1522,2 Hz

Unfortunately R6LDD went QRT and is actually not QRV. Very interesting spot and would worth to
get more than one :-)

That was the last QRO transmission with 5W Graham

Txing at 20dBm since 19:22 utc
Reports on my monitor from -1 to 0dB

So far not monitors in Opera at less than 1000Km

Hi Graham, MF

Good idea. Let's see where is the imit

I have just connected the U3 directly to antenna. Have not measured power yet but may be under 500mW
I'm not using the 3xBS170 but a mosfet driver instead, ICL7667 if I can recall correctly

Spots in WSPR dropped to just the EA monitors

Hi Luis
 
Nice going  for  5  watts,  but  -8 dB  with  75 % of the  signal  recovered ,  your  nearly  +30 over the  limit .. can you drop the  power down by  20 dB ?  say 50 mW ??

Hi MF

Back home !

Antenna is up again and I' transmitting with only 5W from a small PA

I will take the opportunity to install the 100W PA in the terrace, as originally planned

Txing WSPR and Opera8 every 12 minutes
