Digital on FRS / GMRS??

[K4DPA]

I travel most of the state of Florida many times every month. I have a radio installed in my truck and while I travel I like to listen to FRS / GMRS as well as all the business band frequencies. I recently have discovered what seams to be a digital platform being used on many FRS / GMRS frequencies. I can't tell if it is DMR or P25. However I do know that is it some type of digital format being used on these frequencies. I have both P25 and DMR radios that I would be able to use to monitor and find out. However, trying to find the group numbers or NACs is too time consuming. Does anyone know if this is usual? Thanks.

PS: No radio police or negative comments. Thanks.

Thread moved to GMRS/FRS forum.

Not legal on FRS and MRS. Possible dPMR. There are some cheap radios out there that likely are bein programmed for those frequencies. dPMR is not authorized for use in the USA. Not compatible with DMR/p25

 

[K4DPA]

@KD8DVR yea that's what I thought. I don't think it's dPMR because we're I heard this was in a rural area and people here don't tend to be radio smart. Lol Who knows tho. I thought it was crazy.

I have a radio dedicated specifically for GMRS and leave it on scan 24/7 (carrier squelch) to monitor all activity. I must say that here in the SE Pennsylvania and Central/South Jersey area we've had a marked increase in GMRS/FRS activity, I did notice the digital mode (sounded like Mototrbo) over GMRS frequencies but what I heard was digital activity in the repeater mode. Maybe some repeater owners haven't read the FCC rules lately.

@Starion1 I really don't care about the rules. The FCC doesn't enforce anything anymore. However I just thought that it was odd to hear digital on the FRS / GMRS bands. I wonder if it's businesses or if it's just someone that has a repeater and uses FRS freqs for personal coms. Lol hahaha Ether way I find it odd. I've been looking for a easier way to find out someone's color code, time slot, and group number on DMR, because you have to have all that right to even listen to DMR. Lol

@mikepdx Well that's the whole point of the question. Why is there digital on FRS or GMRS?? So there for it belongs in the thread that I put it in to start with.

It's still in the thread that you put it in to start with.

You asked why there's digital on FRS or GMRS which is clearly a question for the FRS/GMRS forum.

Unfortunately, many people don't care about the rules, and do whatever they want to.
Others are just ignorant of the rules.

(Yes, I understand that just because you stated that you don't care about the rules, that it doesn't mean you yourself ignore them. Your question wasn't about how can you do it, it was about has anyone else ever heard it themselves.)

Either way, although I myself have not heard P25, DMR, NXDN or any other digital mode on FRS or GMRS frequencies in the Phoenix metro area, it does not surprise me that you are. I think it surprises me that more people aren't reporting hearing various digital modes on those frequencies.

Who cares? It's just a radio. Calm down.

I'm sure that these folks though the same thing until their $30,000 bill from the FCC arrived in the mail.

I am calm.

That is one of those very few and far between cases. I am sure they didn't pay the whole $30,000. That's extremely too much for using a walkie talkie. As much trouble we are in as a nation and we are worried about the frequencies that some business is using. I believe that is way to much. As a nation we have way more important things to worry about, than someones radio. Good lord. LOL

What you are hearing is most likely the weak front end of most scanners / cheap radios being hammered by businesses using moto-turbo on nearby business freqs.

Ie, if I take any of my cheap dual-purpose frs/gmrs radios to the top of my building at work, the front end is severely overloaded and desensed by the nearby high power business repeaters.

On the ground, nice and clean for the most part, but there are still occurrences. Same with my scanners.

if you really want to find out what it is, grab a $15 SDR dongle, download some freeware such as DMRDecode, SDR Sharp, etc and start chasing waterfalls.

Which Make/Model of Scanner.
Where in FLA

My Scanners, P25 and ole Analog regularly get images from other sources (Not intermod) but actual images. 467 get's 470/482 T-Band, VHF Feds get 151-154 Ambulances

Lock one radio on the Freq and then search and see if it could be elsewhere.

Finding the NAC should be easy, put it in Auto/Search if it is P25

I have the Uniden BCD396T and it doesn't support the NAC decode. I want to buy the new Uniden scanner that will decode the NAC's.

So this software like DMRDecode will tell you what group number someone is using?

GMRS P25 on 462.700

Some radio techs use P25 in the clear and encryption here in Yuba City, CA on 462.700 MHz.
I just lock out the channel.
