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

Here’s the actual text, but I think you’re reading too much into it. The licensee can maintain control by verbally commanding a person: (2) The licensee must maintain access to and control over all stations authorized under its license.

But I find no mention of it in any announcements on the FCC website. Damned bureaucrats.

Happy New Year, Adam! Don’t worry about it. You’re a decent man. I have no resolutions. Not that I do things right already, just that I’m not going to change.

No apologies necessary. At least you figured it out. Ferrites on the power leads might help. Keep your ground wire short; go to a chassis ground nearest the transceiver. The positive line should run all the way back to the battery or fuse box near the battery.

What has changed?

I would drive somewhere else and see if people still report the whine. Do you have a different radio you can swap in?

Did your neighbors have any fancy Christmas lights on at the time? I’m more inclined to believe it’s something external since your engine is off at the time. Does your antenna require a ground plane? I’m not certain the corner of your roof rack would substitute for one.

I think you’re asking about testing the resistance between the center pin and the shield on the SO-239 jack on the rear of the radio. Testing it with a multimeter imposes DC which might give some continuity reading which might change over time. There are inductors, which appear as shorts at DC and there are capacitors which will appear to be continuous while they charge, but then block DC. A continuity test there isn’t necessarily indicative of anything. Are you parked near an electrical transmission line or underneath lit streetlights or other electrical equipment when transmitting?

That’s actually kind of clever, but annoying to everyone else, for possibly a $12 radio.

Then it is the charger (I suspect). Those little inexpensive chargers are very often terrible RF generators. Here’s a further confirmation: take the battery off of the radio and put it into the charger without the radio. Does it still create noise?
