Take a look 30Hz higher as well.  
 
 Just checked V & I   and it looks to be 6 Watts into 100 ohms loss R. 
Antenna is 7m tall with a large top hat, so say   Rrad =  0.01 ohms. 
 
So something like 40dB loss with about 0.6mW  radiated.  
Allow a few dB directivity, call it  0dBm ERP.

Hi Roger

 

I’ve switched my 500 wspr off and am now looking for you on 137.5 (136).

 

My ant is sub-optimal and not as good as Lord Osborn of Wade’s but we shall see

 

Chris – car boot tomorrow or steam rally perhaps?

 

Pm me

 

Cheers

 

 

Jim
