[TenTec] Omni VII on SW AM

[Bob McGraw - K4TAX]

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.
