Just turned the Omni VII on here on the desk.  Antenna is a 256 ft center fed 
wire via balanced feed to a 4:1 balun and then direct to the input of the Omni 
VII.   To investigate the area of concern that one writer expressed,  I tuned 
across the BC band and the SW bands.  Found a station that was 42 dB over S-9 
according to the S meter.  Ran the RF Gain from 100% down to 0% and back up to 
100% while listening with the 20K IF filter and DSP filter at 8 KHz.  No pops, 
ticks, or distortion was observed in the audio.  AF Gain at a very comfortable 
but somewhat loud 35%.  Stepped through all 4 AGC positions with the only noted 
artifact occurred when AGC was OFF.  Tried it in LSB and USB with a couple of 
stations.  Again no issues of concern.

Found a couple of weak stations in the S-4 to S-5 range with the RF Gain at 
100%.  Still no issues of concern.  Selective fading did have the normal 
distorted effect on the AM signals.
