In my haste to get to bed last night, I neglected to post here that I
successfully copied M0BMU's WOLF transmission in a 25 minute recording made
from 0135 - 0200 UTC (19 Mar). There are two lines of clear copy at this
point. I say that, because I'm not done tweaking the various command line
parameters yet. As Jim has pointed out, you should enter the correct
sampling rate for your sound card, and this appears to be more important
with weak signals. Also, I find that adding short delays in increments of
1/20 second (-s 400, -s 800...) may transform partial lines into complete
ones.

I'm located in central Massachusetts, about 80 km west of Boston. This is a
fairly noisy residential area, and I'm stuck with a loud carrier just above
137 kHz that does deafen my receiver somewhat. Hardly an ideal location. I
believe that my neighbor nearest the loop antenna turned their light dimmer
off around 0145 last night, thereby helping my situation greatly!
