Thanks Gary and Markus.
 
Loran is still proving useful as a calibration aid!

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?

My QRSS30 (slow CW) LF beacon will continue until this evening. Only one report so far G3WCB at 101km.

Message:       XBM in QRSS30, pause, then G3XBM in 10wpm
Freq:             137.6748kHz
ERP:             50uW (antenna 80sq m vertical loop)
Location:       JO02dg, Burwell Cambs

Any reports and screen grabs would be much appreciated.
