FCC Salinas/watsonville

[Delivers1234]

So I called the interference on gmrs 3 to the FCC about 4 months ago. this is in the Salinas Area, California. FCC called me asking how it was affecting Channel 3. They thought I meant the tv channel. Anyway, I recorded the sounds and sent him my gmrs ID.

Its nice that they called. I hope they can fix channel 3. it sounds like its bleeding from another business frequency.

I forgot all about that. I was going to try and direction find it. Will be interesting to see if the FCC does anything about it.

 

[Delivers1234]

Update: The FCC man called (I'm sorry I forgot his name). He found the possible source on a mountain around Mountain view? He will call me Thursday and ask the owner to shut off the antenna to see if GMRS 3 clears...

Q: Can I consider this my first Fox Hunt?

 

[Doink]

I don't know if you've considered but 462.6150 is the 3rd harmonic of 152.205. I don't live up there but I do see in the database that channel is licensed up in your neck of the woods. For what its worth.

 

[mmckenna]

Certainly could be.

I looked at all the licensed users in the area, and the FCC is showing them all as analog. The interference is digital, or at least sounds like it.

I was driving up highway 101 from Paso Robles last night and had the UHF radio with me. All along 101 from the south end of the Salinas valley I could hear it. I've heard it as far north as Santa Cruz. That's pretty strong for being a harmonic.

Good idea, though.

Hi. The fcc called again to check if i still heard the signal on GMRS 3. I still had it. The operator says it looks like "john deere" equipment in the farming area sending gps info continously. he will continue to look into it. he did not seem to think it was a 3rd harmonic frequency. He divided the frequency by 3.

 

[Delivers1234]

update: The FCC tech said some antennas were shut down. He said it is from the john deere drones or something that remotely controls farm equipment. My mobile did not pick up the interference but when I went to my home base 2nd floor apartment, it was still there.

Could someone see if they here anything on channel 3 and where you are at? Im in Salinas.

 

[mmckenna]

Yeah, I'm still picking it up on the rooftop receiver above Santa Cruz, but the signal strength is much reduced.

 

[KeithKenobi]

I spoke with the FCC too. Told them it was It is the RDO Equipment Rental WQYP976 and WQQD780. The FCC shut down some of the transmitters but there is still one weak one I can hear from Santa Cruz.

{ have heard noise on 462.6125 GMRS 3 for l the last two months here in Salinas. It is not constant but in periodic bursts, but did hear some analog FM weak few times. What is your interest? Do you have or use a GMRS 3 repeater near Salinas? I have a few local repeaters but not GMRS.

 

[mmckenna]

And looks like the FCC has made a move to take care of this...

Looks like your complaint worked. Nice job!

 

[KeithKenobi]

Thanks for the Link!! There is still one weak signal plaguing the Monterey Bay area (fairly strong at Hwy1 and Jensen Rd).

 

[mmckenna]

Hmmm, that's close to me, maybe I'll try and take a look later.

Thanks for the info! (I see NO license for 462.6125)

We also found a location near Chowchilla, and contacted the ranchers.
Between Rd 15 & Rd 16 and between Ave 18 1/2 and Ave 19
37.0239 -120.2630

There was also a VERY strong signal just south of King City (I assume the Cattlemen Rd location), I did not have a chance to DF.
FCC was notified and I don't know if they had time to look into it.

***BUT: As of today, the 462.6125 frequency is clear!

PS, I understand the FRS channels are voice only, but what types are legal?
IE DMR? P25?
And what about GMRS?
Thanks!
Keith

Thanks! I heard what sounded like DMR on 467.5625 in the Santa Cruz area.
I will park my receiver there when I get home.

Could be. I know there's a fair amount of folks that pretty much ignore the FCC rules on GMRS. Also, there are shops that will "dump" users on FRS/GMRS frequencies and not properly license them.

 

[KeithKenobi]

Yes, and the Fishermen on Federal Law, Low-band Police or wherever they want to be.

Let's keep an ear to FRS 3 and cross our fingers!
