Have an Icom R-75;

- wondered why it tunes all the way up to 60,000

whats broadcast in the frequencies between 30,000 & 60,000

any lists out there ?

2-way radios, remote control toys, cheezy wireless devices in general,
and a TV channel.

- So why the hell they put it in there ?

( Sounds like a total waste of time . . )

See FCC Spectrum chart URL:
http://www.ntia.doc.gov/osmhome/Chp04Chart.pdf

Since it is a VHF range, generally it is line of sight.
Coupla of services come to mind

1. Amateur band -- 50 to 54 Mhz sometimes Hams experience Sporadic E
propagation for long range skip contacts. But most often it is line of sight
either simplex or repeaters. Modes for Hams are CW, SSB, AM, FM, Data

Channel 2 of the USA TV band is here -- 54- 60 MHz

Since it is a VHF band, can't imagine any "broadcasting" there except
Channel 2 TV
Other services here - cordless phones around 43 to 49 Mhz, Fast food Freq,

These frequencies are VHF (as opposed to shortwave) and what you're
going to hear there usually depends primarily on where you live. I say
"usually" because low VHF signals do tend to skip around when
conditions are right.

This slice of spectrum will primarily yield two-way communications in
the FM mode, rather than broadcasting - the exception being TV channel
2 (54-60 MHz). The territory from 30-60 MHz also includes the six
meter ham band (50-54 MHz),

While most folks would probably use a scanner to listen down here,
typically scanners operate in FM and maybe AM mode. Hams and others
wanting to listen to SSB, CW, and digital signals in the 6m ham band
would need a receiver such as the R-75 or a ham transceiver for that.

Also, as I mentioned above, low VHF signals often tend to skip around
a lot, and a good communications receiver such as the R-75 can be a
better tool for catching low-VHF DX than a typical scanner.

As for frequency lists, this again depends on where you live - you
might try RadioReference.com or Google up some other scanner frequency
list for wherever you are.

Hope this helps,

There's also a ham band from 50-54 MHz where CW, SSB, and digital
modes are regularly used. Typical consumer-grade scanners, which
operate mainly in FM and maybe AM modes, are pretty much useless for
monitoring those signals. You need either a ham transceiver, or a good
communications receiver such as the R-75, for that.

At times when propagation is good you just might find some interesting harmonics
of SWBC stations above 30 MHZ.

dxAce...The California Highway Patrol (CHP) is very active between 42 & 43
Mhz, as well as some freqs in the 39 Mhz range, and some in the 46 Mhz
range. Also activities in the higher VHF ranges. 154.905 is a great freq as
it is the car to portable repeater. If you hear that, you're within 5 miles
of a cruiser g. Keep the CHP freqs going when I drive on the freeways.
Hasn't kept me from getting a ticket one time (oh well....), but it makes
for informative and interesting listening while driving. Hope this helps
everyone.....Eric

At the bottom of the sunspot cycle, you won't hear much in the way of
international broadcasts of anything in this range.

During the summertime you may occasionally hear ham band openings in
the low 50 mhz range. I've heard the California Highway Patrol is
still around 42 mhz, but that may be rumor; that'd take a pretty big
whip antenna. Around 56 mhz and up you'll hear TV stations, channel 2
and up.

Here are a few apparently still in use:
