Scanners Covering TV Spectrum
Wirelessly posted (Mozilla/5.0 (X11; Linux i686; U; en-US) Gecko/20081217 Vision-Browser/8.1 301x200 LG VN530)
Does anyone know of a list of scanners and communications receivers that can pick up 72-76 MHz, or, since TV stations have vacated it, the whole range of 54-88 MHz?

For casual listening you may find these useful.
The USB SDR dongles will cover that range.
(for around $15-$20 and free SDR# software)
You could use them with a laptop.
There's also an app in the early stages of development for using them on smart phones.

Some info here: SDR# | A Software Defined Radio in C#
And here: rtl-sdr
Versions available:
RTL2382U - The ADC and USB data pump. It is mated with one of the following three tuner chips.
E4000 - Tuner. 60MHz to 1700MHz
FC0012 - Tuner 50MHz to 1000MHz
FC0013 - Tuner 50MHz to 1700MHz
R820T - Tuner 24MHz to 1850MHz
One of mine tuned to 72 MHz.
You can see almost 2 MHz of spectrum at one time and tune to any frequency of interest.

Ok, that's one option, thank you. I don't have any computer, or even a smart phone right now. (3G multi-media phone is what I'm using.) Having looked around here a little bit, most current Unidens cover 72-76MHz, correct?

If you are close, try the close call with the 396.

Hijacking Posts Moved
I moved the 4 hijacking posts from the discussion of wireless microphones to its own thread in a more proper forum. Please don't hijack others' threads for your own off topic discussions.

FWIW, the Baofeng portables do 65 to 108 mHz, but the manual, such as it is, says that this band is set up for commercial FM broadcasts, which would mean a passband of about 200 kHz which would not be of much use for LMR NB or WB reception.

The original thread was a Mid-Band, 72-76 MHz discussion. I continued that, and expanded the frequency range to the entire range between 6M and FM Broadcast now that TV transmitters are gone, and it has been mentioned elsewhere that the military uses it.

What makes you think there are no TV stations in the 54-88 MHz band?
They didn't all move to UHF.

And how many are left, out of what was there prior to the digital conversion?
The point is, I'm looking for a list of scanners/receivers that cover the Mid-Band 72-76 MHz, and preferably the entire 54-88 MHz range. Thank you.

TV in the USA has NOT vacated those frequencies. Broadcasters on physical channels 2 to 6 still use those frequencies. Although now if they are digital (ATSC), they can be numbered with any valid channel number (not just 2 to 6).

I don't think I can be anymore specific. What scanners and/or other receivers cover the frequency range of 72-76 MHz, or the range of 54-88 MHz in part or in whole?

I can't access the wiki via my phone, but those links aren't going anywhere untill I can get on a real computer. I did see elsewhere that most newer Unidens will cover at least the Mid-Band if not the whole range between 6M and FM Broadcast. Thanks.

Any other receivers that anyone knows of? The info isn't just for me, but for any who may be interested in giving this range a listen to, to hear what may be within range of them.

Military radios used to cover 30 to 75 MHz in 50 kHz Steps.
Most non-USA versions of scanners, such as the UBCD396T, will usually cover somewhere in the range of 66 to 88 MHz.
