Open carrier 467.6375 from nearby home

[Dispatrick]

For several months I've been picking up an open carrier on 467.6375 DCS-734 (FRS-11).

One day I got in my car and took me literally less than 10 minutes to locate it coming from a home about 3/4 of a mile east of mine. I confirmed it by taking off my radio antenna sitting in front of the home and still seeing full signal strength. I also saw an antenna on the side of the home.

Is there a device like a baby monitor or an audio feed for a camera that uses this frequency also, or maybe something custom the resident made?

I doubt it would be an open carrier from a radio for this long without a burnout of the equipment.

Might be something like this:

Audiovox GMRS-2000 FRS GMRS Weather Multi Radio Base Station No A/C Adapter | eBay

<p>no charger as is </p>

Pretty easy for it to be stuck transmitting. Low power, so wouldn't necessarily burn out. External antenna may or may not be connected.

If you are not hearing sounds from inside the house, might be something else. Might be some cheap Chinese transmitter. Might be poorly shielded local oscillator noise.

Or write them a letter and send it by mail.

Knock on the door, make a new friend.

Pull up in front of the house...
Kick it up to 50 watts...
And say...

"Can Ya Hear Me NOW?"

Willing to bet it's a hosmart intercom they use frs/gmrs

Help the guy or move on. OT posts deleted.

How many other houses are nearby?

I also saw an antenna on the side of the home.

What kind of antenna?
How do you know the signal you found was coming from that antenna?

It's fascinating when I monitor FRS channels 12, 13 and 14 because there's a Big Blue Swim School around the corner in the Shopping Center. Sometimes I do a quick radio check, and I'll hear the instructors talking about how they hear trucker on those channels. What Truckers would use FRS for casual conversation? I realize Dump Truck Drivers would probably use FRS if the part of a Road Construction Crew, but over the Road, heck no.

You're telling me, that there are some folks who can't tell the difference between FRS/GMRS and CB radio. Come On! I almost afraid to go around and make a suggestion to them about use CTCSS or DTCSS. I mean it won't do anything to prevent individuals from listening, but they don't have to listen other users who maybe on those same set of channels

Many truckers use Frs, in my area to chat in groups as they're going down the interstate. It's nothing new. A few even use Amateur radio repeaters.

The average person knows nothing about two way radio. They cannot tell you the difference between CB, FRS, amateur radio, or XM radio. It's all "just radios".

There are people that cannot tell you why CB channel 2, FRS channel 2, Marine VHF channel 2, and TV channel 2 cannot talk to each other.

I'm under the larger "IT" umbrella at work. 99.9% of the people in the IT industry couldn't answer those two things above. They think my trunked radio systems utilizes WiFi.

So no way a swim school instructor, dump truck driver or IT person is going to be able to know the difference. They just go on Amazon, type in "radio", or "walkie talkie" and buy the first thing that pops up that looks good. Same reason there are people that buy Baofengs and use them on the frequencies they have straight out of the box.

Expecting anything different is not realistic. That's coming from someone that's been doing this as a career for 30+ years, and trains police officers on how to properly use their radios. Everyone has to start somewhere.

Most people I know think Trunked radio coms are contained in a large box.

I remember decades ago buying the red, green, blue dot frequency radios, and they would come with the license application in the box, with a warning that you needed to be licensed to use them. It didn't work terribly well (hence those 3 color dot frequencies becoming a complete wasteland) but it was better than nothing. I don't remember when that went away.

I think the red and green dot frequencies became two of the MURS channels if I remember correctly. 154.570 & 154.600

They did, because it basically became a free-for-all. Hardly anyone there was actually licensed.

[Edit] I believe it was Blue and Green. Those were the two most common, though Red Dot was in a few of the radios. I still have some old color dot radios.

Because of Motorola offering VHF radios for sale in retail stores preprogrammed, the FCC ended up turning Green Dot (154.60 mhz) and Blue Dot (154.57 mhz) frequencies into MURS channels.
