Questions. In Reach, FRS Radios, NOt What you think.

[ghosthunter]

So a crazy thing happen the other day at work.

A employee brought in some cheap FRS radios to use. And the darn things were picking up cell phone conversations.
Channel was 11-1. My cell phone conversations.
So I turned off my cell phone and the darn things were still picking me up talking to my off cell phone. What the heck?

Now I have used FRS radios everyday for 30 years never had this happen.

Any ideas.




Question 2

I have a InReach mini. Turned off right now, meaning I suspended service.

Now if I were driving in the mountains and went off the road in the dark where no one would know. Could I turn on my InReach the unit. And would it be reporting my location? On a suspended service .

I guess my question is , if I was missing could law enforcement ask GEOS to look for my InReach and could they find it. Even if my service was on suspend?

When you suspend InReach service plan, is it a switch at GEOS or does the network lock you out.?

1) I think you might have been pranked.

2) i remember seeing a warning when I suspended that the location would not be available to emergency services but can't find it on the website.  If it were still "on", many people would just use it for free, all you would lose would be texting.  I do know it doesn't show location on your account or send location e-mails when not active.

1. Don't think so. I was right there and I tried to change settings on the FRS to get it to stop and could not. I turned off my phone and still communicated with the FRS. weird.


2. I agree wont show on your account. But are they just filtering you out . Can they see it on their end. ?

It would highly unlikely for a FRS radio to be able to pick up a cellular phone frequency.  Channel 11 runs on 467.6375mhz and depending on the cell service, they run anywhere between 800mhz and like 40ghz.  Pretty far apart for one to hear the other.

Inreach needs an ACTIVE plan for SOS or communication function.  Mapping works without subscription. Minimum plan is $11.95/mo

Aside from the encoding of cellular signals.

Nope not really.  You can get harmonics off anything transmitting at a certain frequency.  It depends on your front end on your receiver of the recieving radio.  Frs radios are pretty wide on the front ends.  I would be sceptical but not out of the relm of it happening.

Nope.  Not really.  Cellular signals are encoded in such a way that you're not getting much of anything short of a slight noise-level increase.  You may get some amount of harmonic, but not in the way you would get a harmonic from a signal transmitted in the clear with the same modulation the FRS radios are using.

Big money is spent developing such schemes to ensure that only big money can decode the signals.
