>From 'ancient' measurements made back in the VD beacon days ... the difference between a loop made from (mil spec) RG-11 and #12 copper is -3.77 dB. This was based on measured R of identical sized loops in the same identical location and with the same soil moisture content. 

TAG was previously running RG-8 and now #12 copper ... one can assume RG8 characteristics are very close to RG-11. This may help explain the current lack of WOLF decodes.

Andy, thanks for looking. Sorry I can't slow the ramp speed down more in 
for the visual callsign. Maybe one of these days I'll get a newer 
Ultimate3S with more control.

I've been looking for TAG also with not even a hint of decode. Strange 
since years ago it came through even in September. I did learn that the 
very old wolf gui code can have issues when run on a Windows 7 PC. When 
I ran it to measure the frequency on one of my PCs the result jumped all 
over the place. The source was a GPS-locked SLM thanks to W1VD and the 
signal was solid on Spectrum Laboratory. I found that if I ran the 
program with administrator privileges the frequency measurement was 
stable. I also found it worked fine when run as a regular user but with 
compatibility mode set to Windows XP, SP2. That's what my PC was years 
ago. Just in case there was still an issue with Windows 7 I ran last 
night using my old Windows XP laptop. Same result - f=0.000 solidly when 
calibrating but no hint of decode even integrating over 32 96-second 
periods. I do currently have a weak spur up several Hz from 185.8 kHz 
but don't see why that should matter.
