It wasn’t a stupid question.

Welcome!

1. It really depends on the repeater how much traffic you hear, but the nature of Famished that you only hear one transmission at a time. Let us know if I misunderstood your question. 2. Tune to the correct repeater channel. Program the repeater’s input tone or code into your radio as the TX CTCSS or DCS. At first, leave the RX tone empty so you hear all traffic; you can always go back and set it if you receive too many transmissions that don’t come from the repeater.

Hi John, For GMRS and FRS, the FCC has designated 22 specific frequencies for our simplex use and 8 more for transmitting to the repeater. The channels are interlaced. So tuning to an “in-between” frequency might be interfering with other services or other channels. You’ll definitely want to read the regulations to see what frequencies we are allowed and the power and bandwidth: § 95.1763 GMRS channels. The GMRS is allotted 30 channels—16 main channels and 14 interstitial channels. GMRS stations may transmit on any of the channels as indicated below. (a) 462 MHz main channels. Only mobile, hand-held portable, repeater, base and fixed stations may transmit on these 8 channels. The channel center frequencies are: 462.5500, 462.5750, 462.6000, 462.6250, 462.6500, 462.6750, 462.7000, and 462.7250 MHz. (b) 462 MHz interstitial channels. Only mobile, hand-held portable and base stations may transmit on these 7 channels. The channel center frequencies are: 462.5625, 462.5875, 462.6125, 462.6375, 462.6625, 462.6875, and 462.7125 MHz. (c) 467 MHz main channels. Only mobile, hand-held portable, control and fixed stations may transmit on these 8 channels. Mobile, hand-held portable and control stations may transmit on these channels only when communicating through a repeater station or making brief test transmissions in accordance with § 95.319(c). The channel center frequencies are: 467.5500, 467.5750, 467.6000, 467.6250, 467.6500, 467.6750, 467.7000, and 467.7250 MHz. (d) 467 MHz interstitial channels. Only hand-held portable units may transmit on these 7 channels. The channel center frequencies are: 467.5625, 467.5875, 467.6125, 467.6375, 467.6625, 467.6875, and 467.7125 MHz.

Thanks for the reminder of how to print the official copy. I always have to fumble around a little bit too.

Nothing about the general personal radio services regulations nor those of part B (FRS) or part E (GMRS) support the position that a licensed user has a greater right to the 22 shared channels.

Are you sure?

95.531(b) One-way communications. FRS units may be used for one-way communications that are emergency messages, traveler assistance communications, voice pages or brief equipment tests. § 95.533 Prohibited FRS uses. FRS units must not be used for one-way communications other than those listed in § 95.531(b). Initial transmissions to establish two-way communications and data transmissions listed in § 95.531(a) are not considered to be one-way communications for the purposes of this section.

You’re joking, right?

I agree and both broadcasting and one way communications could be cause for citations, but it wasn’t always 24/7 according to his description. It appeared once for what sounded like a period of days (that would be 24/7 at the time) then reappeared again a few weeks later. This is a clear case of parents being ignorant about the technology they’re using. But using GMRS frequencies, regardless of how important a person might think his communications are, includes sharing with ignorant people. I like @WRUE951’s suggestion to educate the parents, but if it’s kids with a set of FRS walkie talkies using VOX, there’s not much that can be done legally.

Calling it a “GMRS repeater frequency” implies more than actually exists. 22 isn’t dedicated to repeaters. It’s available for FRS simplex, GMRS simplex, and as the output of a GMRS repeater. It might suck, but legal FRS users have as much right to use it as GMRS users. But the actions you describe are excellent reasons why people shouldn’t use wireless intercoms or baby monitors, regardless of the frequency.

I remember reading about that shortly after it happened. Some articles include the fact that he’s a ham in the headline, but that had nothing to do with the fact that he was disrupting their communications on 151 MHz and attempting to redirect firefighting resources. I would have loved to see the interaction when the official drove over to his location and clarified things. I have absolutely no sympathy for this jerk. He’s the kind of guy that reflects poorly on all hams.

That’s a good point. One way transmissions are limited to certain uses; a baby monitor isn’t one. But if it’s a two way intercom triggered by sounds I’m not sure what the FCC might think.

Or a legal use of an FRS channel.

Another company that sells FRS baby monitors: https://roaroutside.com/pages/faqs?srsltid=AfmBOoqPv7k7oop_6MIL4grQqkl1l5HDLiGFFCud_MW_eNhDSoMX_R-8 The point is that if you have 300 people who rely on GMRS, you’re already vulnerable to a communication failure of your very important something. At the very least you need to develop contingency plans that include meeting up on other channels in case the channel you rely on is busy and training so they know more than turning them on and pushing the PTT.

It happens to the receiver, although a strong enough RF signal could certainly interfere with a transmitter.

Doesn’t matter. You can’t reserve a frequency.

Take that frequency out of your scan list.

Someone has their radio turned on with VOX turned on.

Are those two radios close to each other when you transmit? If so, the transmitting radio may be overloading the receiving radio, causing a condition called “desense.”

Welcome!

Before doing that, what about the spark plug wires? Also, see this: https://forums.radioreference.com/threads/rfi-interference-how-to-eliminate.247596/

My old one had it, but when I downloaded a new copy it wasn’t there.

But the good news is that @Photog1018 has hundreds of programmable channels.

It’s also subject to the scope conditions and requirements of FAR 101 for moored balloons. https://www.ecfr.gov/current/title-14/chapter-I/subchapter-F/part-101
