MURS Simplex Repeater !


Recommended Posts

Hello near Mt. Jackson Va is a Simplex Repeater on 151.880Mhz it has a PL of 156.7Hz.

I live nearly 60 miles north and can hit it with no issues. So it must be well located on the

mountain top. If it's legal it's nice but i have no idea nor did i find any info on if it's legal.

A "simplex repeater" uses a simplexor (or store and forward) device which contains a recorder. Some are for a fixed length and others are VOX. I suspect that you've found one with a VOX. The only way to know for sure is to give a 10 count and see if comes back. If you only hear the same 3 second kerchunk, it's likely that it is a regular repeater.

 

I have an older Zetron Model 19 Simplexor on my ambulance squad's base radio. It works fine, although we rarely use it. It is only triggered by a unique Quik-Call II tone set that dispatch uses only when our EMS repeater is off line. The simplexor records the dispatch when activated. Then it sends out our regular pager tones and plays the recorded dispatch. It's not a bad system although we rarely have need of it.

"Since you are already "breaking the rules" by kerchunking the "repeater" you may as well give a brief voice transmission as well, such as "Testing, 1, 2, 3" and see if it is "parroted back" to your radio. ph34r.png"

 

 

 

Thanks for the information guys! I didn't know I was "breaking the rules" by saying "Radio Check, 1,2,3,4" and then giving my call sign on a repeater frequency. Can you clarify?

I wonder where the line is drawn for the "repeaters are not allowed" on MURS frequencies. I could set up a repeater but not use it, or I could use someone else's repeater that I had nothing to do with setting up. Is it the person who set up the repeater who would be at fault, or the transmitting station? Because in all fairness, I wouldn't expect to be activating a simplex repeater on a MURS frequency if I were transmitting.

 

Anyway, here's a group who's none too shy about their MURS repeater: http://www.artscipub.com/repeaters/detail.asp?rid=32221&ln=WB9VR_repeater_information_on_151.880_in_Monee,_Illinois

 

So it's definitely a thing. Probably a handful or more of them out there, and I'd bet it's not at all worth the FCC's time to go on a fox hunt.

the best way to understand a parrot is go to Argent Data Systems and take a look at theirs. i have one and works real nice and fits the kenwood/baofeng as well.

as of now yes the rules do not permit even a simplex repeater for MURS. however, im sure in a post collapse etc or SHTF scenario if I had critical scenarios i would even use one. but they do have their place. one example is you can use a simple handheld with the parrot, and place it up on a mountain top someplace as a tool to test RF coverage etc. i've done that and when that works you remove it and place up a duplex repeater etc. 

but if someone has a MURS repeater going on. just keep in mind its against the rules.  uhmmummmmmmmmmmmmmmmmm

" wonder where the line is drawn for the "repeaters are not allowed" on MURS frequencies"

 

95.1311 Repeater operations and signal
boosters prohibited

 

Murs stations are prohibited from operating as a repeater station or signal booster.  This prohibition includes store and forward packet operation.

 

 

 

Hence a parrot or simplex repeater is a store and forward device

the repeater owner is the control operator and, according to the FCC, responsible for the repeater, whatever the service. so if it is illegal to have a repeater on MURS frequencies, then the folks that set it up are on the hook. that said, if a MURS radio user connects to a repeater, when he or she figures that out, they must stop using it, since it is also illegal to use a repeater on MURS.

All this information is pretty accurate and it has always been an interesting topic. There is always this possibility as well:

 

§95.1317   Grandfathered MURS Stations.

Stations that were licensed under part 90 of the Commission's Rules to operate on MURS frequencies as of November 13, 2000, are granted a license by rule that authorizes continued operations under the terms of such nullified part 90 authorizations, including any rule waivers

 

 

But on that note there are a few neat and cool things we can do with it if willing to spend the time and money to do them:

 

§95.1313   Interconnection prohibited.

MURS stations are prohibited from interconnection with the public switched network. Interconnection Defined.Connection through automatic or manual means of multi-use radio stations with the facilities of the public switched telephone network to permit the transmission of messages or signals between points in the wireline or radio network of a public telephone company and persons served by multi-use radio stations. Wireline or radio circuits or links furnished by common carriers, which are used by licensees or other authorized persons for transmitter control (including dial-up transmitter control circuits) or as an integral part of an authorized, private, internal system of communication or as an integral part of dispatch point circuits in a multi-use radio station are not considered to be interconnection for purposes of this rule part.

 

§95.1307   Permissible communications.

(a MURS stations may transmit voice or data signals as permitted in this subpart.

(b A MURS station may transmit any emission type listed in §95.631(j) of this chapter.

(c MURS frequencies may be used for remote control and telemetering functions. MURS transmitters may not be operated in the continuous carrier transmit mode.
