Confirmed KMS-4 Radio Reception on UHF

Further to my last, I have copied a second pass with timings that 
closely match Spacetrack TLEs.

The signal is weak and experiences deep fades with obvious modulation.  
Hear the recording below to form you're own opinion.

The signal seems to have drifted up in overall frequency since last orbit.

Here's a 75MB wav file of the entire pass that anyone can hear.  I 
screwed up making a wideband recording due to unfamilaritity with the 
software but I hope it helps with the analysis.  It's just demodulated 
audio not the raw 190KHz bandwidth.  It starts off uninteresting but 
gets very loud with signal a few minutes in around (6-7 minutes) and 
near the end of the pass.  Best viewed with something that can visualize 
the signal.
