Socal GMRS

[Hype6477]

Hello Everyone!

I am new to GMRS I, recently received my licenses. I am trying to use my Baofeng UV-5R to hit the repeaters near me (462.725 and 462.625) and, I am having no luck. No one is replying idk if I have the tones right or not I tried all the ones I saw posted inrepars to this sight.

2) Is there some local GMRS group in the San Fernando Valley area that's still active?

Was your mention of "456.725" a TYPO?    That is a Part 90 ONLY frequency.

I think you mean 467.625/462.625 depending on the repeater you may need a PL code, either DCS or CTCSS to key into the repeater. Also make sure you are transmitting on the 467 frequency and listening to the 462 frequency.

Question: Amature radio offsets for repeaters are designated either as a + or a -, with a standard amount of offset for that frequency. The + or - is what direction from the transmit frequency of the radio?

you are correct sorry it was a typo sorry

Hype6477 - Send me a PM with the correct data and I'll edit it for you.

For UHF frequencies, a + would be 5 MHz up and - is 5 MHz down.

So 462.xxx + = 467.xxx

The + or - is from the receive frequency, not transmit. On GMRS the transmit is + 5 MHz from the receive frequency. That is also common usage on 70cm ham radio, but some repeaters do not use that standard.

Thank you, "recieve frequency " brings it together.

There's an open repeater on 600 at Mt. Wilson (see MyGMRS database), and travel tone in the LA area (not sute about SFV coverage). Try also Club 650 for technical discussion, but that's not a super active repeater. The primary tones listed in the database are correct and I can hit 600, 625, and 725 from here.

 

625 and 725 are quite... crass. They may ignore radio checks. 625 has a rather insensitive receiver so you need a fairly strong signal to hit it. 725 also needs a good signal but that has exceptional coverage in the SFV.

Hey Elk Hunter, Here's a little more information for you, for when you get your ham license...

 

The standard offset for UHF repeaters is +5 MHz from the receive frequency.  That goes for ham, GMRS, and commercial. NOTE: The standard is not always followed, but for the most part, it is.

 

On VHF, there is no standard for offsets on commercial repeaters, and they seem to be all over the road. The standard offset for VHF (2-Meter) ham repeaters is 600KHz, or 0.6MHz.

Another tidbit: The standard (again not always followed, but mostly) is that ham repeaters above 147 MHz use a positive offset, and those below 147MHz use a negative offset. Thus, you will see repeaters like 146.820- (in which your transmit frequency would be 146.220) or 147.060+ (which you would transmit into at 147.660).

 

I hope this is useful information for you. -73

Hi Jones, Thank you, it all helps.

I'll also +1 this - thank you guys, I never knew how the ± notation worked.  

[WRAF213]

Yes:

600 is Wilson

625 is Harvard

All work as listed on the website. I don't think any of the alternate tones work.
