Dear Urban, LF Group,
I had good copy of SM5EUF/5's Jason beacon signal between 1300 and 1400
today. The signal was centered on about 137.679Hz - about 4Hz above
nominal. There are some Loran lines within the +/-2Hz bandwidth of the
signal - there was also some QSB, and when SM5EUF faded a few dB, the
signal was swamped by the Loran lines, and copy was corrupted for a while.
See the attachment, which shows the spectrum centered on 137.679kHz.
A little later, around 1440utc, I heard Urban calling CQ in CW near 136.5k.
The signal was very weak, but the noise level was also very low, so about
RST439. I called a couple of times, but no response.
Cheers, Jim Moritz
