I was playing around with Unden's Air (VHF) Search mode on a BCT15X today and it stopped on numerous carriers minus any audio between 108~111MHz. Any idea why? I'm using a FM-Notch filter no less.

birdies/stuff around the house, computers and their routers and modems.
i have one computer that loves putting out a signal on 144.0, 243.0 and some others.

I thought about that but with the air band starting at 118MHz why would Uniden even include frequencies below 118 in their search?

You running into VORs maybe? Mike
the aero band s 108-137, voice is 118-137, NavAids like VORs are 108-117.95.
How can I tell? I wasn't familiar with VORs.

the snowbirds are listed with a 116.0 frequency, it would be nice to search and find them.
so who else might be in there ?

i was going to add, and it is in the above article, that there is an ID in the signal. either morse or voice.
so it would not be a totally dead carrier, just boring to listen to. and try 75 Mhz near the airport.
