Thanks for the information Paul!

If you tune the passband, you hear three peaks of noise - at approximately 145.928, 938, and 958. Although some like to avoid them due to noise, they are actually the most sensitive areas of the transponder. 938 is very popular with low power rovers for this reason since a low power signal at low elevation can be much louder there than at the center of the transponder.

I would think .940 would be one, that is one area I see/hear people
around.

Alan, You mention documented "sweet spots" can anybody point out where we
can
find this information. I saw something on the AMSAT-BB many years ago but never could find
that
email again.

The Mode B transponder has, due to varying noise and sensitivity, some documented "sweet spots." Mode A, while not as popular, does get some
use.
Are there any observed equivalent frequencies?
