[Lowfer] Lowfer results over night

Spent time looking for JAM and PBO before moving to the lowfer watering 
hole. Conditions have not been exceptional to California (NDB MOG on 404 
kHz LSB very modest in strength) so without a super antenna and quiet 
QTH like Steve, AA7U, who copied SIW at 1503 miles once, JAM just isn't 
feasible. It's clear that JAM is sending at rate QRSS30, but the true 
frequency is uncertain - the recent capture by Neil, W0YSE/7 at 
https://www.dropbox.com/s/ew20qv7up6ny46a/705%3DJAM0002.jpg only shows 
an audio scale, not the RF frequency. Also, comparison of VX9BDQ WSPR 
reports shows that Neil's frequency is likely off by several tenths of a 
Hz. Nonetheless, the wide version of ARGO allows one to certainly cover 
the frequency somewhere ( I ran centered at 187016 Hz since that's what 
Andy, KU4XR thinks is correct) but, as expected, nothing but spurs were 
seen last night.

The attached capture spans 30 minues and was completed at 1109Z. The LHS 
shows results when center-tuned to 187016 Hz, tuning then moves to 
187200 Hz for PBO (no signal noted), and finally moves to the lowfer 
watering hole at 185300 Hz. There SJ comes in fairly well but it's hard 
to separate the Morse characters since the transmission is QRSS20 and 
ARGO is set to QRSS30. WMS and TAG are present with fading. Both perked 
up later.
