Jay,
Very impressive captures! I've been seeing WEB here decently but didn't
tune around the watering hole last night. Instead, I spent some time
looking for WMS. Best I could do was to identify occasional signal
traces at 187.490 kHz using QRSS60, slow.
A bit earlier the 518 kHz Navtex RTTY stations in Nuuk, Greenland ($04W)
and Kodiak, Alaska ($12X) were as good as I've ever seen them (though I
don't monitor Navtex often). Unfortunately that didn't translate to copy
of new NDBs in either place. The 5 W, CW signal on 497 kHz from
WD2XSH/31 in VA was also detected earlier, thanks to QRSS.
WD2XSH/34 has been transmitting PSK31 every 5 minutes on 507.0 kHz this
weekend to study 500 kHz propagation for emergency communications.
Although others at about the same distance (434 km) seem to copy 100%
24/7, I just barely detect the signal during the day though at night
copy is often 100% here too. The meager daytime reception prompted use
of decoding programs other than MultiPSK, version 4.10. Dated versions
of Digipan, CW-Hamscope, MixW2, and MMVari showed no improvement, but
Digital Master 780, version 4.0, SP4 build 1910 was substantially better
and has been adopted as my "standard" PSK program. I should note that
WD2XSH/34 has also run tests using PSK10 and that mode is not included
in the Digital Master PSK list, but MultiPSK does handle it.
As to the beacon, the word isn't good. Had no luck resonating the
antenna with additional inductance and instead found forward power peaks
with minimum variometer inductance rather than maximum. It won't be hard
to remove inductance but first some repair work is needed on the
transmitter because the power it delivers to a dummy load is way down.
That will have to wait awhile as I'm going out of town shortly.
