[WriteLog] No signals showing in DigiRite Receive

[Gordon LaPoint]

I have DigiRite V 2.2.2.11 - built by AA5AU installed with WriteLog 
V12.54A.  Its decoding signals just fine but I have a blank waterfall, 
with one pixel line at the top that is showing signals, what do I have 
set wrong?

Everything else seems to be working, and I used this setup last year for 
the FTRoundup without problems.

Thanks,
