Hi Dave, Roger, LF,

The line appearing at 137676.8 (137676.5 actual) is a mystery - maybe it's a Loran line.

I have a spread sheet which some one compiled (can't remember who) which shows your line as being a Loran line at 137676.42Hz.

Spread sheet attached for anyone who may find it useful. I am not sure what the right hand columns refer to.

Looks like Marcus just pipped me to it.

Roger, LF,

 

Latest screen grab attached. I switched to my 1.2m tuned loop, and your signal improved by at least 3dB, maybe as much as 6 dB. See attached screenshot.

 

BTW, I make your frequency to be 137676.0. I have a small frequency error which makes signals read high by 0.3 Hz. The line at 137680.40 is a locally generated signal in 137680.0, which is pretty accurate.

How many watts are you puttting into your loop?
