Ron,

I believe that the bands are scanned top to bottom and it is just looking
for a match for "more than begin" and "less than end".  So yes, I think
what you are proposed should work.

On the RX Gain, this field is only to adjust the Panadapter and Meter
readings so they will be more accurate when you have a device with
significant gain/loss inline.  Changing the value should not affect the
audio samples at all.
