My guess is they don't want interference on their radios. Some of the Carnival and Royal Caribbean (MSC doesn't operate here) ships here in the Tampa area use 467.550 and 467.575 MHz (GMRS repeater input frequencies) and 467.5625 (GMRS Channel 8), both analog and digital depending on the ship. I did bring some FRS radios on a cruise and found them to be almost useless. The ambient noise level with crowd noise, band playing, etc made it so I couldn't hear the HT even if I wanted to.

Don't have that radio to comment about the software, but here's the scan setting you need to change per the manual.... Configure via:Menu → Radio → Scan Mode. Channel Mode: Scans the channels listed in the channel memory (requires power-on scan to add).Frequency Mode: Scans frequencies based on the selected step Setting. ● Time Mode: Resumes scanning if no operation is performed within 5 seconds after detecting a carrier signal. ● Carrier Mode: Stops scanning upon detecting a carrier signal and resumes scanning 5 seconds after the carrier disappears. ● Search Mode: Stops scanning immediately upon detecting a carrier signal My guess is you want to change this option to "Carrier Mode"

Since you have a laptop with a SDR dongle, try giving Spektrum a shot, it might help you out in scanning across a wide range of frequencies. It turns your SDR into a makeshift spectrum analyzer and works pretty good for what it is. Download: https://github.com/pavels/spektrum

If your picking it up on VHF as well, there is one more thing you can try and rule out is a strong CATV (Cable TV) leakage problem within your home caused by a loose connector, damaged coax, bad amplifier if you have one, etc. CATV is very broad band. If you have cable, try disconnecting the cable from the ground block going into your home and see if it goes away.

If your hearing it across all channels at the same time, I'd would think not a GMRS frequency unless it's somebody sitting within a few hundred feet of you overloading the receive on your radio. My guess would be a commercial user very close by on a nearby frequency or your radio is picking up some harmonic of another frequency. If it was a GMRS frequency and strong enough to splatter across all the channels at the same time, you should pick it up S-10 (full signal strength) on the channel they are operating on.

Not up to me to say.. The IC-7610 is a nice radio but expensive, not really pocket change. That said, I just purchased an American made Flex 6400 for about half the price of a 7610 ($1500 used with some nice options) and couldn't be happier. The prices on Flex stuff drop like a rock once discontinued.

Can I have your pocket change please? The IC-7610 costs $3500.

A friends daughter used to work for a disaster recovery chain cleanup company as a sales person. She was more or less an ambulance chaser but for flooded or fire damaged homes and businesses. The company monitored the scanner for fire dispatch the next county over and would dispatch her to try and sell their services. I asked why she didn't work in our county, her answer was "because we can't scan the fire department" (our county is all P-25 encrypted).

Icom ID-5100A. SD memory card slot allows for recording of receive, transmit or both. A 32GB card will hold hundreds of hours of recording. Pop it into your laptop and copy everything over when you want, the recordings are standard wav files or replay on the radio.

Probably not the problem, but is it possibly plugged into the wrong port on the radio? The face plate and the programming cable both use the same (RJ-45) connector. Make sure the faceplate cable is plugged into the front of the radio and NOT the side port (programming port).

Yesterday? Pic obviously taken from this TikTok video that made the rounds a few weeks back....

There area few exceptions to the rule. We get a few ships that come into the port that use 467.550 and 467.575 MHz (GMRS repeater input frequencies) as repeater outputs that cause interference on our local 462.575 repeater on occasion. Their repeater inputs are 10MHz down, 457.550 and 457.575 MHz and are allowed digital. They are not governed by FCC but by the ITU.

Interesting results.... https://www.youtube.com/watch?v=F7opritxml8

I looked up 50 watt GMRS radios awhile back on Amazon for giggles, the wife saw my history and decided to get me a GMRS-50V2 for my birthday. Installed it to see if it actually did 50 watts (it did 51). I am around 500ft from RR tracks and the trains always radio in to dispatch from right around my house as the next street over is the dividing line between two RR yards/frequencies. When the train keys up on VHF, it wipes out the UHF/GMRS band on the 50V2. Never had a radio do that before. Might have to try your recommendation.

Except OP's looking for a hand held.

The funny part is those cheapo Baofengs have a lot of features that commercial radios do not have. Things like tone scan, vfo scan, program from the keypad, VHF reception, FM broadcast reception, NOAA reception, etc. Guess it depends on what you want to do with the radio.

Years ago I was out driving when I came across a S-64 Skycrane helicopter lifting a AC unit to the top of a new building. I had to pull over and watch, just the geek in me I guess. It looked like the rotor was moving in slow motion and it's propwash (rotorwash?) was rocking my truck back and forth from 1/4 mile away. It was a cool thing to see.

Wasn't something like this already tried a few years ago? I started off with a lot of enthusiasm but died off real fast.

Yet the CPS software works just fine in Windows, strange how that works.

Except the DMR HT's you have tested and sent back for the simple reason you couldn't get them to work in Linux.

Strange, my N9TAX GMRS/MURS sweep shows around a 1.3 SWR in both 462.5MHz and 467.5MHz in the GMRS band.

Just look at the 2nd paragraph "On March 17, 2025, agents of the Enforcement Bureau’s New York Field Office, using direction finding techniques, located and monitored transmissions of the Station at 7.200 MHz." It's the norm for the clown parade of users on that frequency.

No it's not. Majority owned by CTE International, headquartered in Italy. US-based operations continue to be run out of Kansas City, Missouri, but they are part of a larger international company.

Wally World FRS bubble pack. Picked up a few of these for a project. I put in parking availability detectors for the truck lot in multiple rest areas around the state. Two miles before the rest area there is a digital sign that shows how many slots are open and also online. I had to prove the system by having a person count and document times every truck that came in, another person to count when they left and me in the middle to verify the numbers every 15 minutes for a week or so. The radios couldn't make it from one end of a rest area to the other, I had to sit in the middle and relay. One of the guys left his radio powered on when he threw it in the back of my truck with a bunch of other crap. A couple times I heard a voice for a second or two and it went away when driving, had no idea where it was coming from. A week later I got a low battery chirp on the radio and tracked it down. At least the batteries last well over two weeks.
