Report it to the FCC as interference.

Gender?

The 22 FRS frequencies are exactly the same as the first 22 GMRS frequencies. There’s absolutely no difference in the frequencies but there are differences in the power limits. None of the 22 are reserved exclusively for FRS.

No, reverse polarity has nothing to do with electrical polarity. RF is AC. SMA connectors have an outer threaded sleeve and an inner pin/socket. Sometimes the SMA connector on the radio will have the male pin paired with the female threaded sleeve. The antenna will have the female center socket surrounded by a male threaded sleeve. But it’s possible to order SMA connectors that pair the male threaded sleeve and the male center pin. The matching connector will be the female sleeve and female center connector. So there are four permutations of the SMA. I don’t know which is considered Reverse Polarity. I just buy what looks right. Most of my radios have a female threaded socket and male center pin, but one has a male threaded sleeve and female center socket. Just be careful to exactly match the mechanical configuration.

There is a switch. Immediately below the original question, over on the right, is a pair of buttons. You can choose to sort by VOTES or by DATE.

HamStudy is the way to go. It’s free to use, but I would encourage people to buy the app for their phone or tablet and study using it when they’ve got some time to kill. Much cheaper than the ARRL books and it changes when the questions change and it really allows a person to follow a subject to the level of detail that appeals to them. I used HamStudy to study successfully for all three tests without owning a single ARRL book (at the time anyway; I’ve picked up some since.) I really enjoyed using HamStudy (if it’s not apparent .)

Well, first, only the GMRS transmitter is certified. That’s 95.1761, parts a-e. The regulations say nothing about certification of receivers. https://www.ecfr.gov/current/title-47/chapter-I/subchapter-D/part-95/subpart-E/section-95.1761. Second, the FCC established channels in 95.1763, parts a-d. According to 95.1763(a), Repeaters may only transmit on the eight channels called out in 95.1763(a) called the 462 MHz main channels. Third, the 467 MHz main channels are established in 95.1763(c). The limits here are a little more subtle: 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). So, those eight channels are specifically reserved for transmitting to a repeater (or by the debate inspiring Fixed Stations) and their frequencies are intentionally spaced 5.000 MHz from the eight channels set aside by part a, so it’s both convenient and the convention to establish repeater pairs that take advantage of the spacing and that’s how GMRS radios are manufactured, but nothing prohibits configuring a repeater to receive on any of the 22 channels established in parts a, b, or d and no regulation that I can find prohibits transmitting through a repeater on those 22 channels. Silly maybe, maybe even useless, but not non-compliant. Think of how confusing that could get.

You wouldn’t bork your radio with the wrong adapter. It just wouldn’t fit. Just make sure it looks like what you’re adapting to.

No such rule exists.

No apologies needed on my behalf. I was just explaining.

He mentioned that in his review. I think he’s trying to find out if anyone else has received it.

Although they’re programmed this way, no regulation requires it. It’s inconvenient to people that buy GMRS radios, but there are several examples within the pages of this forum of repeaters that have a non standard offset, yet comply with regulations.

As long as the repeater uses one of the frequencies from the main 467 MHz channels to receive and transmits on one of the main 462 MHz channels and is licensed appropriately, it is a GMRS repeater, even if it doesn’t have an offset of exactly 5.0000 MHz. You’re right that most “standard” GMRS radios don’t easily handle an offset that isn’t exactly 5.000 MHz but there are ways around it, especially with radios that have dual watch.

Just have grandpa’s son, daughter, or any other adult in the family buy a license. It covers grandpa and grandson and the rest of the family. It doesn’t have to be purchased by grandpa. Or just get grandpa a GMRS radio and stop worrying about the license. Chances are extremely low (statistically almost zero unless he causes trouble) that anyone will know or care.

Program only the transmit tone in your radio. Leave the receive tone blank or set it to TONE rather than TSQL. That will allow you to hear the repeater and anything else that’s on that frequency. Second, make sure you are close enough to the repeater to hear it. Many repeaters simply don’t have much traffic so you might not hear anything, but if you are close enough eventually you’ll hear something.

Sounds like it, but it shouldn’t matter. Have you tried a different mag mount?

@WSCL528 You said you receive from the repeater on 462.700 MHz. What frequency do you transmit to the repeater? The traditional input frequency for the repeater would be 467.7000 MHz, but some repeater owners have chosen other frequencies from the eight available.

On my phone: click on the hamburger click on browse click on clubs That will show you the club directory. Scroll to the bottom and click on “start a club “

It looks like you’re planning to put one repeater in each home. If that’s so, how do the homes communicate with each other? You can’t go repeater to repeater. Or are you planning one repeater, centrally located, with all of the family members bouncing off it with the handheld radios?

So sometimes it takes about a week. It should go through soon.

I’ll report your post to Rich. He’s good about helping although I recently reported a false alarm so maybe he has me on his ignore list.

Here’s a video that explains how trap vertical antennas work:
