72-76 Mhz range

[FrankJ]

Is there any voice communications in this band? I hear a lot of paging and instrumentation in this utility band.

Not in the USA, probably more activity there in places like the U.K.

My place of employment used to have a couple of voice frequencies in this band, that linked their remote bases to their VHF simplex communications towers, but they are no longer in use. That particular system has now been replaced with VHF repeaters.

Take Care!

CHP in my county use 70mhz to linked their remote bases.

I seem to recall there are wireless microphones in that range.

 

[hotdjdave]

Microphones and navigation. TV channel 5 starts around 76 MHz.

The California Highway Patrol and Caltrans (Calif. Dept of Transportation) use these frequencies for links to sites without microwave links available, especially sites where commercial power is not available. When you are able to receive such a link, it can be great. Think of it as being able to receive everything the remote base on a tall mountain or tower can receive, sometimes from considerable distance. The frequencies are low enough to allow signals to bend a bit, but are not subject to skip as much as lower frequencies. In my case I could monitor a link clearly that was located nearly 70 miles away in mountainous terrain. My fun got spoiled when the state Dept of Comms people added greatly to the solar and battery capacity at the site, placed about a dozen more propane tanks for the backup generator, and then put the link on microwave.

This frequency range is often overlooked by hobbyists and can sometimes have some great gems.

There are numerous channels in 72mhz for remoted control. Model airplanes and boats ect...

 

[N4JNW]

Model Aircraft are 72 Mhz.

Model Boats/Cars are 75 Mhz.

72-76 Mhz

Hello fellow scanner

according to the FCC Frequency Bandplan the range you are asking about is broken down as follows.

72.000 - 73.000 MHZ: Intersystem, Paging, RC

73.000 - 75.460 MHZ: Astronomy

75.460 - 76.000 MHZ: Intersystem, Paging, RC

I hope this helps you out

I believe CDOT here in Colorado may still use telemetry in that range for snowfall measurement devices or "snowflake counters" as they were called at one time.

 

[YalekW]

Mostly remote control signals, microphones, etc. Ive always wanted to listen to this range, but most of the scanners don't come with these frequencies.

5 1/2 year old topic, keep an eye on the dates.

Hi Danny:

I understand what you're saying but is there a rule here that prohibits someone from rekindling any interest in a 5 1/2 year old topic? If so, could you share it with us?

I'm another member that never saw the original, so this topic interested me.

[mikewazowski]

No, there is no rule.

 

[reconrider8]

the only real rule that i can think of even like that is bumping your own thread to keep it alive

RF-based hearing assistance systems, such as are used in churches and sometimes theaters, are also on 70-some mHz. Williams is one manufacturer. More modern systems today use IR as their transmission medium, one manufacturer being Sennheiser. The RF systems can be heard all over the venue's neighborhood, whereas with the IR systems you have to be in the same room and line-of-sight with the signal emitter.

Another thing is how has the migration of TV to DTV channels affected the 72-76 mhz band. I had a half dozen channels on them years ago. They were a PITA to get licensed for due to the possibility of TV interference. Now with DTV nowhere near these freqs I would love to put up some voice repeaters on them.

 

[Thayne]

We still have 2 of them to link two remote paging transmitters to the terminal

It may be better to start a new thread though, as I find the jump in time of
posts can be confusing i.e. years-old info that may no longer be valid/relevant.

72-26MHz in Canada is used (among other things) for low-power helmet
radios used by work crews etc. I see licence entries that appear to be remote
clock synchronization in institutions such as schools. I've heard very little
myself, other than the buzz of RC models, except what sounds like a wireless
in-building broadcast (for hearing-impaired?). I don't think it's used for LMR system
linking as in the US but I could be wrong.
