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.

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:

I have the same trait. Almost all engineers do. Usually it’s fun. Sometimes it’s frustrating. If you decide you want to try to make the pieces into a GMRS antenna I’ll do more research. I wouldn’t discard the pieces. Some ham would enjoy playing with them.

I don’t know how it will affect the gain. The saying with antennas is “Everything affects everything.” Do you have an antenna analyzer? I wouldn’t start hacking away based on my suspicions. But if you can take things apart in a way that allows you to put them back together easily, then feel free to play around.

Not badly. You’ve only cut off some metal. You can always replace it. Is the center coil (which I think is a trap) easy to remove from the lower element? Do you want this antenna to be usable on two different bands or just GMRS? If the answers are yes and just GMRS, then take the upper element and trap coil off and see what the bottom element measures for SWR on 433 MHz. If it’s good, then you can start tuning it for 462-467. You shouldn’t have to remove much and maybe you can test it with the pieces left over from the top.

Are you trimming above the center coil or below? I suspect the lower element was the UHF element, the center coil is a trap, and both elements combine to form the VHF element.

What’s your call sign?

Take the antenna off the meter.

But each channel has an allotted bandwidth.

4. It depends on what’s changed and what you mean by no longer a GMRS radio. 5. No 6. Many, maybe most.

3. Scrambling isn’t blessed by the fcc regulations but neither should it result in an FM frequency shift outside of the bandwidth allotment.

2. The frequencies used for CTCSS tones are mostly standard but some radios don’t have all of them.

1. So you are asking about transmitting on one of the channels not set aside for transmitting to repeaters and receiving on another. Like 462.550 and 462.675? There’s no prohibition against that but it needlessly ties up two channels.

The new question pool is already available to download for free. But honestly if you learn and understand the concepts in the old test you should be able to pass the new test. The concepts haven’t changed.
