We get comments and questions from customers who are interested in GMRS repeaters and want to set up their own. Such is the case in regards to our Wouxun KG-1000G repeater video tutorial. Some of this feedback comes from hams who are familiar with the rules of using repeaters on the amateur radio service, with the natural assumption that the FCC rules for GMRS repeater stations are the same as those for amateur radio. While this is mostly true, there are some exceptions that make owning and operating a GMRS repeater a little different, and perhaps easier, especially if it is for private use.
To clear up the confusion and separate fact from fantasy, here is the truth about GMRS repeaters.
According to the FCC rules under § 95.1751 GMRS station identification, "Each GMRS station must be identified by transmission of its FCC-assigned call sign at the end of transmissions and at periodic intervals during transmissions except as provided in paragraph (c) of this section. A unit number may be included after the call sign in the identification."
A GMRS station refers to any Part 95E type accepted device that transmits and receives signals on the GMRS radio service. This includes portable handheld walkie talkies, mobile radios and base station units. It also includes GMRS repeaters.
The rules also specifically state how the call sign (ID) must be transmitted, as outlined below:
(a) The GMRS station call sign must be transmitted:
(1) Following a single transmission or a series of transmissions; and,
(2) After 15 minutes and at least once every 15 minutes thereafter during a series of transmissions lasting more than 15 minutes.
(b) The call sign must be transmitted using voice in the English language or international Morse code telegraphy using an audible tone.
So, yes, just as with a ham radio repeater, a GMRS repeater is required to transmit a call sign. However, as simple as it sounds, it is this specific point that seems to cause some confusion.
Most publicly accessible repeaters operate unassisted, without a station operator present 24/7. This means that in order to comply with the rules, there must be a system in place to automatically transmit the call sign or station ID at the required intervals. In fact, such a system has long been used by amateur repeaters everywhere, and is generally the accepted norm among members of the ham community. Therefore, it stands to reason that some sort of auto ID controller would be required to operate a GMRS repeater as well. And for the most part, this is correct.
However, there are scenarios in which an auto ID isn't necessary at all. According to subpart (c) under the same section:
(c) Any GMRS repeater station is not required to transmit station identification if:
(1) It retransmits only communications from GMRS stations operating under authority of the individual license under which it operates; and,
(2) The GMRS stations whose communications are retransmitted are properly identified in accordance with this section.
In simple terms, the repeater does not need to auto ID if it's intended for use as a private or closed repeater system.
Consider, for instance, a family farm or ranch. Since a GMRS license covers the entire family, the repeater does not have its own callsign. The repeater is also identified by that family license. each family member using the repeater provides the call sign and their station ID over the repeater every fifteen minutes, which suffices for the repeater ID.
To repeat, pun intended, if it is a private repeater operating solely between operators of the same GMRS license such as a single family, and each operator is properly identifying their individual stations as required by their license, the repeater itself does not need to transmit an ID. This is simply because the station ID is automatically being transmitted by each individual operator relaying the call sign.
An automatic repeater ID function is only necessary if people other than those covered by your license are also using the repeater. And that's the truth.
GMRS repeaters do not need to self identify if each station using the repeater properly identifies. You did not address #2 in your statement requiring identification. (2) The GMRS stations whose communications are retransmitted are properly identified in accordance with this section.
Do you sell a plug and play option for the KG-1000G’s that can be programmed to key the radio in repeater mode and transmit the call sign over the air at the right intervals?
We do not currently have a device to automatically transmit an ID. The KG-1000G repeater mode isn't really intended for a permanent or public repeater configuration. It's best used as a temporary repeater or as a private repeater for use by families, such as a family farm, where a repeater ID is not needed.
So I have top learn Morse code?????
If I had a GMRS repeater and more than one call sign is transmitting (or transmitting their ID), but, they were in the same family, would I have to get a call sign for the repeater (station) itself and would it have to auto ID? Hope this makes sense.
GMRS and ham repeaters operate under different rules. Amateur repeaters are generally assigned their own call signs. A GMRS repeater cannot have its own call sign. Instead, it operates under the call sign of the licensed GMRS operator who owns the repeater. If each member of the family operates on a different call sign but can still qualify to legally operate under the call sign of the family member who owns the repeater, technically speaking, they would just use the family's call sign when operating on the repeater. The key is that someone has to give the family call sign they are using on the repeater every 15 minutes and that should satisfy the requirements of a repeater ID. If there are different call signs, it would likely be considered a public repeater and it would have to auto ID the callsign of the repeater owner, unless that individual wanted to do it manually every 15 minutes while the repeater is online and active.
New to this. How do I go about getting license or callsign if figuring the license provides callsign
Your callsign is issued to you by the FCC after you purchase your license. You can apply for a GMRS license at https://www.fcc.gov/wireless/universal-licensing-system.
Hello, im new to the GMRS and just got my license. I have a question about trying to find a repeater, how do you know if your allowed to contact or talk to a repeater you find? i assume there is Ham specific ones and GMRS specific ones, been trying to find something to let me know so if im not allowed to contact a Ham one i dont by mistake, thxs for any and all replies
The protocols for contacting ham repeaters are a little different from those for the GMRS. With a few exceptions, most amateur (ham) repeaters are open, meaning that as long as you are a ham operator with a valid call sign, using the repeater is not usually an issue. GMRS repeaters are different, primarily because many are private and operated by individuals for various activities and purposes. Ham repeaters operate on different frequencies than GMRS repeaters, so I wouldn't worry about the chances of accidentally transmitting to a ham repeater with an FCC Part 95 type accepted GMRS radio. We covered this topic in detail with instructions on how to find GMRS repeaters in your local area in episode 68 of The Two Way Radio Show Podcast titled An Introduction to Radio Repeaters.
I have two radios, do I have to program both radios with the same repeater to talk to my wife?
We need more information. What make and model are the two radios? What is the distance from which you are attempting to communicate between the two radios?
Confusing..........
can an owner of a GMRS repeater beacon their call sign? maybe every hour on the hour.
