Thanks to Todd's help with MultiPSK, DDH47 was decoded nicely around
midnight local time. I prefer to tune with USB so reverse reception was
needed. There was quite a long wait while weather information in German
displayed before the ID (CQ/frequencies/RYRY) was transmitted at 0627Z.
MixW2, another program I have can decode the non-standard RTTY of DDH47.
It's RTTY mode settings allow one to set the baud rate and the shift to
arbitrary values (thus avoiding the MultiPSK overstatement of shift=85
Hz). It also allows numerous choices for the character set. However, the
program is not free so my version is still on trial. The trial days are
only counted when you run it, not by the calendar, so it still runs, but
won't much longer. I only used it to decode DCF39 on 139 kHz back in
2008. Not sure if that station is QRV now but it transmitted a pulsed,
non-standard RTTY (200 baud, 340 Hz shift, inverted, ASCII 8-bit even
parity) that none of my other RTTY programs could handle.
Conditions seemed back to normal though it was nice to decode the DGPS
Cape Race, NL station on 315 kHz. The nearby station on 287 kHz is much
stronger. The watering hole looked like it did some days ago with just
WMS coming through, along with local SIW. Didn't see anything of UWL
last night and EMP was barely noticeable. On 137 kHz both MP and XGJ
continued to come in well enough to see with QRSS3 bandwidth. They also
both made it into the VEYTIL grabber at http://www3.telus.net/sthed/argo/.
