[Lowfer] XES on 137 kHz using DFCW

[Garry Hess]

Noticed XES coming through the F1AFJ grabber nicely last night. 
Transmissions were dual-frequency CW at 137.779 kHz (+0.2 Hz shift). The 
signal here was just noticeable until about 0300Z 9/25/09, when it 
quickly rose and became strong until the final transmission around 
0500Z. That behavior is similar to the recent WD2XES WSPR transmissions 
9/21/09. Looked for TAG again with no luck. Better compare the soundcard 
calibration using Loran-C harmonics to the value I get using a 
GPS-referenced 1000 Hz signal (and 100 kHz to establish tuning error). 
Too bad there aren't regular Wolf signals to boost one's confidence that 
decoding is working optimally.

British Columbia NDBs were in very well around sunrise indicating 
reception of 500 kHz hams out west should be viable when/if they begin 
high power transmissions.
