Ok im totally a newb here but i have two questions.

i had a shop program my 3 radios a while back for Short track racing ie Spotter to car. but at times i am picking up kids talking on those FRS radios through my spotter radio hit and miss. My question is what exactly determines the DPL code or is it you can use any DPL code that you can come up with or is it freq. specific or could i just find a DPL table to rectify this issue?

the freq they built for me was 462.5625 with the DPL 506 i am thinking there's gotta be a way to stop this interference by maybe switching the DPL?

Also these radio are moto GP300 portables. Any help would be greatly appreciated......Thanks

I will try not to sound too much like the group over at popular wireless, but your radio shop illegally programed your radio on a FRS channel. If you plan to continue to operate on that frequency you are actually the one in violation of Federal Law as you radio is not licensed for that frequency, the power output is too great and it has a removable antenna. Accept the interference you are recieving as I am sure you are causing much more that what you are recieving.

With that said. Change the DPL to one not used by FRS radios and your problem will likely solve itself. There is a list of DPL's and your radio shop that programmed the radio should know these and they can easily check which ones are commonly available on FRS radios.

hmmmm now thats interesting.... so the easy fix would be just change the DPL correct? cause im not going with those guys anymore as i have found out how SHADY they are..not only in this situation.


hopefully the Freq can remain the same if not tell me your thoughts please....

you can apply for your own frequency thru the fcc then if you ever hear something like that you can have a legit complaint? another thing to check is that if it's only one radio that's recieving the interference then it's possible that radio is set to csq on recieve or has the monitor function turned on?

Again, check the programming, and changing the DPL is a quick and easy fix although you are still operating illegally and most likely causing interference to legal users.

Here's a site with the DPL information. (You can probably ignore
the reference to "inverted" DPL codes as these are used/required
when a radio signal is passed through a repeater or similar processor, whereas
your work is with what we call simplex, or direct, operations.)

You can get a regularly licensed frequency and callsign assigned by the FCC which will
be completely legal and still use your UHF GP300 radios. It's called
"itinerant" service and can be licensed for use in all the states so you
can use it everywhere. There is a cost involved, probably in the area
of $200/$300 total the first time you apply. After that it's renewed
every ten years for a relatively small fee. A good radio shop can help
you with this licensing and probably save you some money at the same
time.

Hello :
Not saying this is legal but im thinking it is.
Members please step in and let us know if im corect or wrong.
Couldnt he use UHF Intinerant freqs and be legal ?
Intinerant freqs require no license ????
Yellow Dot = 464.5000 - Intinerant
Brown Dot = 464.5500 - Intinerant
Could he use these which are for local use ???
J Dot = 467.7625
K Dot = 467.8125
Silver Star = 467.8500
Gold Star = 467.8750
Red Star = 467.9000
Blue Star = 467.9250
Id like a clarification on the legal use of these as per his situation.
Thank you.

That is incorrect.....

Not to beat the answer to death but Grog is 100 percent correct.
Itinerant channels require a license -- period. Whoever told you
otherwise was wrong. AFAIK the ONLY non-licensed UHF channels
are FRS.

All RF transmissions must come from a licensed station.

Some stations are licensed by rule, such as FRS, and do not require any action beyond complying with the rules set forth by the code. All others require a license issued by the FCC.

I should have provided further, but some of the rules about Itinerant channels seem to get confused all the time. One thing you won't have to pay for is coordination, since by their very definition they are meant to be used in various locations. So getting a license for Itinerant frequencies would save some money over a license that requires coordination (more money).

Hello :
As usual someone does not read the post completely.
I did not say intinerant freqs were license free .
I was asking thats what all the extra ???? marks were all about.(To clarify it was a qestion)
And where in the post did i say i was told by someone it was = You made assumptions.
I have noticed a few postings where other members seem to step in with no additional valid info and seem rather rude in there responses .
I understand years back this problem existed then and it would appear it may have a few doing it again.
Yeah go ahead and flame me if you want.
You wont find another post out of me like this one anywhere here previous.
I was trying to find other options for the original postee.
Best to just sit back and let others take the rath for trying with ideas .

Can't the original poster just get a GMRS license for $85, and then be legal? Last I checked, you can transmit 2 watts on the "frs" 12.5Kkz channels & 4 watts on "gmrs" 25Khz channels with a GMRS license. Only thing your limited with a GMRS license in reguards to frequency use is no simplex transmit on 467.xxxx 12.5Khz freqs.

The problem with a GMRS license is it is only for use by you and members of your immediate family. If your spotter is a family member then it is OK, otherwise the spotter and any others needing to talk to you need their own license.

Yes, I know there is widespread unlicensed GMRS use. I am just saying what the GMRS rules are.

A UHF business itinerant license would be the best solution and get away from the kids with FRS radios.

Ah, another Intarweb lawyer thread.

Operation on an FRS channel using any radio besides a certified FRS radio is illegal.
Operation on GMRS without license is illegal.
Operation on itinerant business channels without license is illegal.
And, finally, what Rubberslinger's "friends" are doing is illegal.

I would suggest they consider going to FRS bubblepack radios, or licensing a channel.
