[Lowfer] MO, MLS, and PBO

Got an "M" at 189500.1 Hz almost immediately when monitoring was started 
around local midnight. This is consistent with Andy, KU4XR's 
observation. Unfortunately, after that only traces were seen through 
0930Z. The weather may have had something to do with that - the freezing 
rain early in the night turned to just rain with lightning racket and 
fast rising temperatures.

Took a look for MLS and was surprised to find an excellent signal at 
1120Z. Previously had only seen MLS during the day.

That prompted a 1050Z move to 187203.75 Hz to look for PBO since Jay, 
W1VD reported excellent reception there earlier in the evening on his 
live grabber. Guess the move was too late because only a dot dash was 
copied.

The usual two DGPS CA stations did decode but nothing was seen of NDB 
MOG on 404 kHz LSB and the big BC station on 350 kHz was not strong. 
VX9BDQ did decode at -28 dB SNR on regular WSPR, 504 kHz USB on the 
dial, but WF2XXQ (474.2 kHz USB on the dial) was only just noticeable on 
the waterfall. WD2XNS and WD2XKO decoded on 136 kHz WSPRS-15 but not 
DK7FC. Dex had substantial downward frequency drift caused by cycling 
his FT817 IF source at 15 minute intervals. On HF WSPR my IC706MkIIG 
similarly drifts when the internal fan kicks on. Solved that by running 
an external fan over the heatsink fins to keep the internal fan from 
ever needing to run. Perhaps that would mitigate the FT817 as well.
