Just been out to change the Coax from CT100 To WF100, that CT100 was crap, you could peal the insulation with your nail on that CT100!
CaptainJack was 99.9% right with his suggestion, it was the receiver causing me issues, tuner was getting swamped and USALS calcs were wrong.
Took some readings out there just now and was looking very good, I might have just improved SNR by about 2%
I dropped the motor like 1/5th or 0.5mm on the declination just now and can't see it getting any better, was gnats whisker, on 30W im peaking 99% signal and 46E Im hitting 95%, 7W is 43% and even if I tweak things I can't get anything any higher. So I think thats bang on
