Bob,

I've pretty much given up on finding a "master list" on the internet. Try
'airline frequencies' with Google. Is about
as good as I've been able to find.
http://www.freqofnature.com/index.ph...0Freq uencies
has a huge list but it's for CA. Best thing I can recommend is simply doing
a search tween 128.85-132.00 and 136.5-137.0
all 25KCS spacing. You'll eventually come up with your own list and can even
figure out the airport and airline that's using it.

I hear a lot of voice in SE TN so it seems to be the normal mode.

Regards,

SparkS
