Not continuously.

With a 30 second period it sounds like it’s part of some signaling system. For a while various devices were sold that used FRS/GMRS frequencies for non personal radio purposes. Baby monitors, home weather stations, etc. Perhaps it’s something like that. Nothing prevents transmitting multiple CTCSS tones simultaneously with strings of data that include DTCSS codes, especially if those codes are being used to carry other data rather than access codes. Because they’re very short and audible CTCSS tones and DTCSS codes are extremely simple to inadvertently include in a transmission if a transmitter isn’t explicitly filtering them out. Our radios do that; they intentionally filter them out before adding specific ones in while transmitting. Someone’s home control system easily might not. Given the fact that you are able to anticipate when it’s going to be heard you should be able to track it.

Very good point.

This is exactly correct. It doesn’t matter which of the GMRS/FRS channels 1-22 you’re on; if you’re using a GMRS radio you’re required to be operating with a license. If you’re using an FRS radio you do not need a license.

Code editors do not unwind an executable to structured source code like you can inspect in an open source project.

Horsecrap

Why not? At least with open source I can see what’s in the code.

Treadmills make great clothes hangers… A good way to get started is to pick up a Radioddity db20g and swap it to 2 meters and 70 cm. It’s inexpensive and versatile. Most people like them. It’s 20 watts but for those two bands that’s usually enough.

You also have SSB voice privileges on a portion of 10 meters: 28.300-28.500 MHz. Here’s the problem. VHF and UHF radio’s typically do not include 6 meters, even though 6 meters is technically VHF. But 6 meters is almost always included in HF radios, as is 10 meters. I would not try to buy a radio that includes just the bands you’re allowed.

Are you talking about UHF and VHF or HF which will allow you to grow? The Icom IC-7100 goes on sale from time to time for $899. It does all of the popular HF, VHF, and UHF amateur bands. The Yaesu FT-991A is another, but it’s incrementally more expensive. The color spectrum scope is nice though. If you’re really just talking about 2 meter and 70 cm, there are few purpose built “base stations” but many mobile stations that can easily be used in a fixed location. I would look at Icom, Yaesu, Alinco, and Kenwood, although it’s hard to find Kenwood now.

They either mean what they say when they label it open or it’s not really open. I would use it without seeking permission but if you get a chance contact the owner to say thanks.

And less than half the price.

UHF is line of sight until it is reflected or refracted by some atmospheric condition. Google Tropospheric Ducting. Physical features such as mountains can also cause reflection or refraction.

Is the UV32 nearly the same radio except without DMR?

The Garmin Rino screen actually gets brighter and easier to see in bright direct sunshine.

Can’t you eliminate that channel from scanning?

It really helps to know which port to choose if you’re watching the ports in Device Manager when you plug in the cable. You’ll see which virtual port is created by the driver.

Great idea! That makes sense.

Cruise line publish lists of what is permitted or prohibited. For example Royal Caribbean has these rules regarding ham radio and two way radios: HAM Radios or other transmitting devices are strictly prohibited due to potential interference with the ship's onboard communication systems. This does not include baby monitors, which are permitted. Guests are allowed to have two-way radios, more commonly know as walkie-talkies, for onboard personal communications. Basic specifications are as follows: Up to 10-mile coverage range, Up to 5 watts power, Internal Voice, Operated Transmission, No external mounting antenna. https://www.royalcaribbean.com/faq/questions/prohibited-items-onboard-policy

Instead of a receive tone engaged, try setting a receive DCS code in your radio to see if it still receives it. Noise can include several CTCSS RX tones but might not so easily mimic a DCS code. Have you tried listening to other channels that are adjacent to channel 15? Channel 1 is the closest of the GMRS frequencies at 462.5625 MHz. Channel 16 is at 462.575 MHz and then channel 2 is 462.5875 MHz. This might help you see how broad the bandwidth of the noise is. If it’s truly random noise it might be pretty broad, but if it’s a digital signal it should be fairly narrow. A spectrum analyzer like @WRUE951 suggested would be helpful also. Does it still happen away from your house or if your main breaker is open? Try recording the audio for a few seconds and post it to this thread.

I’ve reported your issue.

OP That kind of range is unlikely with GMRS, especially given the physical obstacles highlighted in @amaff’s post, but amateur radio on HF (lower frequencies than VHF and UHF) can probably communicate between Olympia and Puyallup. They also may have linked repeaters for VHF or UHF, which are allowed in amateur radio but not GMRS. Both communities have amateur radio clubs. Consider contacting them for more information: The Olympia Amateur Radio Society: http://olyham.blogspot.com/ Valley Amateur Radio Club: https://www.arrl.org/Groups/view/valley-amateur-radio-club/type:club

That’s okay, it was a very good answer anyway.

Have you checked with RT Systems to see if their software will program that legacy radio and if so whether their software for that radio is available for your computer?

The issues are the constitutionality of deportation without due process, presumption of guilt (again failure to abide by the constitutional requirements of due process), wholesale “roundups” at locations based on “Hispanic presence”, etc. I would go further except I wish to respect the forum rules against debating politics. And don’t get me wrong; I wish to see actual criminals and criminal behavior punished after due process. But none of those issues imply that a person who disagrees with you and your beliefs is stupid. In fact many of them are pretty intelligent.
