30 To 50 MHz: What's To Be Found Here ?

[BOBRR]

Hello,

In the range of 30 to 50 MHz, what "type" of stations are usually to be found in this range ?

For AM ?
For SSB ?
etc.

Thanks,
Bob

In the US everything will be FM. I don't think there is any AM or SSB in that band.
There used to be some AM paging transmitters in Canada. I don't know if they still have those.
What is there? Check out the VHF Low Band Log posts in the skip/tropo forum
Skip / Tropospheric Ducting Forum - The RadioReference.com Forums

I don't know if this is the right forum for this question is it? Anyways-well here in Ca. the Highway Patrol is in the 42mhz range-various state police and park police around 44mhz-cordless phones and baby monitors in the 46 and 49mhz-

Dont know about SSB or AM but it is all mostly FM/NFM and beside what everyone else said its the band i always check for SKIP.

Many state highway patrols use this frequency range - I can think of California and Tennessee off the top of my head. Businesses use it, as do military training camps and the like. Note that some of these services are migrating to UHF digital, but the characteristics of this band, especially long-distance coverage outside of repeater range, should keep it somewhat active for years to come.

Almost all traffic is FM.

Out of all the scanner bands, this is the one most prone to "skip". It's nearly daily across North America in May, June, and July, dying down but not disappearing in the other months. Expect distances of up to 1,500 miles regularly, and almost unlimited distances during solar peaks (we are about 2 years from one).

AM and FM, not likely SSB

Yes, there are still some AM users on VHF Low

I have, in times past ; picked up the California Highway Patrol in West Virginia. Low band is great for catching skip, especially of a night.

If you do the search thing ( put a scanner in search mode to scan a " band" ) do so in small sections.
Example = 42 to 44 mhz. Search for about an hour or so , then change again. Or, right here at RR.Com , punch in the freqs and just listen.

Good list FF-Medic!

I program in the local electric utilities in the 37.46 to 37.86 range. These freqs tend to be used by the line repair crews, simplex, for communication back to dispatch. A couple of times during power outages I've fired up the radio to listen to the line crews tracking down the problem.

Bob, you will pick up a lot of activity on the 33. & 46. from Eastern CT fire/police
