Digital noise on 467.5625

[plughie]

While scanning on the San Francisco Bay peninsula, I have been getting a digital squawk on FRS channel 8, 467.5625 MHz. Is there any shared use between this frequency and public safety, commercial DMR/P25, etc. that should be expected, or is this more likely an illegal squatting on the FRS band? I don’t really want to take FRS 8 out of my scan list, but this is really annoying.

The only legal use is FRS and GMRS. Digital noise could be from a number of things.

Perhaps a spurious emission from someone configuring a digital CCR somewhere in the business bands. Or a deliberate use, figuring the legion of bubble pack users will just select another channel. Hard to say, really.

Sounds way too loud for multiple miles through the woods to be spurious. I’m guessing it’s either a very high antenna or >20W. It’s probably a misconfigured commercial trunked system with an admin who thought, “this frequency seems free!” What could possibly go wrong?

I occasionally hear what I believe is DMR simplex on some of the lower numbered FRS frequencies. Nothing continuous, so it's only mildly irritating, but then again we are just chatting and move to a different frequency with less (or no) traffic. Encountering such while scanning I could see being much more bothersome, especially if it's a strong signal.

Down in the Monterey Bay area, we hear a burst of static on 462.6125. A couple of people have heard it, and what little time I've had to snoop has shown it to be pretty wide spread. Weak signal, but propagates well up and down the coast/Salinas Valley.

Different frequency from yours, but would be interesting to know if the signal is the same. Pattern.

Well I Did a Search on the Posted Frequency and there is Only One FCC Registered as *(ig)* for

ALCON LABORATORIES INC ----
9965 Buffalo Speedway
HOUSTON, TX 77054-5008

Call Sign WPLD-687----Its Listed for 25 Units @ 2 Watts--Mobile (mo)

ULS License - Industrial/Business Pool, Conventional License - WPLD687 - ALCON LABORATORIES INC - Frequencies Summary

Well, that's interesting. Do license by rule services like FRS/GMRS and business's frequencies often intersect?

That was probably a grandfathered license from way back.

No. I would bet that the FRS frequencies on that license are a typo or mistake that the FCC didn't catch.


Grandfathered GMRS business licenses don't have callsigns that new, the radio service would not be Industrial/Business Pool, there would not be a mix of GMRS and IB frequencies, and the GMRS interstitial channels were not available back then.

Can you point me to this grandfathering action?

This all seems kinky. An intestitial pair being grandfathered? More likely an error by the coordinator that has been "rectified".

The FCC has been lax in protecting GMRS from encroachment by Part 90 users . The Part 90 coordinators have made a land grab of the first and last 12.5 KHz of the GMRS blocks with the FCC's help.

GMRS lacks any sort of representation with respect to spectrum matters. The PRSG is one guy, and from what I can tell it is inactive.

It was G-Fathered in 2012--and expires 2022---its all there in blue and white what more is there to explain

Maybe being no more than 2/4 watts made an exception This is Under the Eligability on the License

90.35A1 - APPLICANT MANUFACTURES SURGICAL SUPPLIES. RADIOS WILL BE USED TO COORDINATE SECURITY, FACILITIES MANAGEMENT, & MANUFACTURING.

The 2012 application you posted was for narrowbanding and administrative changes. It was never a GMRS license and has absolutely nothing to do with grandfathering.

Grandfathering means an original site-based GMRS license from before the 1980s rule change remains valid but can NEVER be modified in any way, only renewed. The same applies to Business licenses on the MURS frequencies from before MURS was created.

We Can Argue This All Day---Either Way the Frequency is Licensed as an IG and in the FRS/GMRS Area--I Highly Doubt this was a FCC Mistake After All These Years of Licensing

I Didnt want this to be a Debate--I was Just Posting what I Found in the FCC Database--So Enough with B*****in to Me Where and When i Found This all I was Doing was Trying to Help with a Search

Like I Said the Proof is There in Blue and White

as for the OP--Im Not Sure if its Even Possible he is Hearing what I Posted from Texas to Cali with Only 4 Watts of Juice But You Never Know--Maybe Some TX Listeners on Here can Give some Input and See if You Hear the Same as OP Stated

Well Its Kinda Funny if you Look Carefully the Gradfather Area is Printed as YES on the License---See Here

http://wireless2.fcc.gov/UlsApp/ApplicationSearch/applMain.jsp?applID=6818486

SO Why is this Station Grandfathered and Licensed in the FRS/GMRS by the FCC Then if Since You State its Not---Please Allaberate Your Findings Why Its Not

I live and work in the Bay Area. I've heard digital activity on more than a few GMRS/FRS channels in the past. Some traffic was legit (FCC approved via temp licensing) From what I've read, the FCC allowed GPS and some data messaging apps over GMRS beginning last year. I'm not sure if it encompasses FRS as well. In some cases, I'm inclined to believe that DMR radios are being used on some of the GMRS/FRS frequencies, legal or not.
