[Lowfer] How do I set RF Gain for maximum sensitivity

[Paul Daulton]

Reducing the RF gain will mess up the AVC. While my TS50 lacks an RF 
gain experience with my Pegasus and Elektor SDR indicate best reception 
with RF gain at max. Dave WA5WKO found the same with his TS430. 

Another factor is the AVC rate, My TS50 for instance sets the avc at 
slow on USB and fast on CW. Same with Daves TS430. We have found the 
rigs work better on fast avc when doing beacon work. A static crash 
might take the rec a second or more to recover on slow avc(SSB) but 
immediate on CW setting . For years I ran my rec on usb and did the 
mental subtraction for the 800hz off set. I now use CW mode and the 
offset is built into my rec, I now set the rec freq and use the 800 hz 
default on ARGO and SPECTRAN. For the right hand calibration I subtract 
800hz and enter that number.
