[Elecraft] K2: SSB FL1 OP1 weaker audio output

[JimWMiller@aol.com]

Good Morning,

I've been testing the SSB board and have encountered a problem. I wonder if 
others have delt with the same issue.
1. The audio output of the SSB FL1 OP1 filters are much weaker than FL2, FL3, 
and FL4.  
2. Also when listening to WWV or CHU, USB is louder (6 db) than LSB.  

Transmit seems OK and looks clean on oscilloscope, Talked with a lighthouse 
station yesterday and got 549 in LSB, but used FL2 for receive. 

Here's action taken so far:
1. Recalibrated to WWV. I'm at least within 20 Hz.
2. Read up and used Spectrogram software and adjusted BFO. It looks pretty 
good. No obvious problem.
3. Have *not* rechecked SSB hardware yet.

Any ideas? Any one had a similar problem? 
73 & Tnx in advance,
