That is a Maratrac, the squelch is adjustable thru a variable resistor on the audio/squelch board within the chassis. It is labeled R1132 SQUELCH, and is located very close to the locking handle. Some models have a metal bracket that holds the interface board, (thats the only board in the chassis that is mounted vertically), if you remove this bracket you can see R1132 alot easier, but do not need to remove the bracket to adjust R1132. Clockwise tightens the squelch. One catch though, for this adjustment to work, the radio must have been programmed with the unmuting/muting setting in the RSS, set to And/Or. It comes from the factory set for Std/Std. And in my 15+ years in the business, I have seen only one programmer that changes this setting. Me. Good Luck.

How come the garmin 120 radio isn't compatible with standard Motorola walkie talkies


When programmed to the same frequency and code settings the Garin Rino 120 should match the Motorola TalkAbout line of radios. They are all using the same UHF FRS/GMRS frequencies. Here is a link to the Garmin user guide where you will find the frequency charts on pgs. 100-102: http://www.uky.edu/~jmlhot2/courses/for480/Rino120_OwnersManual.pdf
Motorola TalkAbout user guides can be found at: http://shop.giantintl.com/Manuals.asp
Best regards.

How do I get rid of the squalk after recieving a message?


What you are referencing is "white noise" or "squelch tail". This can sometimes be reduced or eliminated by changing your interference eliminator code from zero (off) to a numbered setting.

Sadly, most modern 2-way radios will have some squelch tail.

Here's a link to the user guide: http://www.giantintl.com/ContentManage/manuals/Moto/EM1000%20User%20Guide%2001-11-08.pdf

Interference on frs radio from motorcycle


Hi Vince,

Have you tried to set the PL or DPL on the radio. This will not stop the interference but it will prevent your radio from un squelching while riding.
If you could post the make and model of the radio i will look for a owners manual for you.

Remember to set both radios the same or make the PL or DPL the same or the radios will not "talk" to each other. PL and DPL stand for Private Line and Digital Private Line both terms coined by Motorola. It is a sub-auditable tone that the radio will listen for and open the squelch when the corrosponding radio is transmitting the tone and vice-versa.
Hope this helped.

You can change the squelch setting with the user buttons, You could set a PL or DPL but the other radio's that you talk to will need the same setting.

Tone squelch


Here is a link to download the user manual for the GP68 http://safemanuals.com/user-guide-instructions-owner-manual/MOTOROLA/GP68%20RADIO%20TRANSMITTER-_E

On your first radio, the one we've been discussing, I believe you have the DPL code set incorrectly. Your radio will go up to the number 126, but this is not the DPL code's number. It is simply a numbering system.

If I read the chart correctly:
DPL 205 equals the number 072.
DPL 023 equals the number 043.

Disclaimer: This numbering system listed in the user guide does not follow any common numbering system. I have other TPL/DPL charts which differ. The above reference is only based on what I have read in the user guide.

I am confident if your radio worked previously at another job site, using other frequencies/PL codes, that your only issue at this time is programming.

As for your unlock issue on the other GP68. Your radio may be in need of repair. The internal button is possibly wornout or has been depressed too far, and is bent on the board beyond the point of functioning.

RPL & TPL tones used in T-5720


The T5720 user manual does not list the TPL codes possible in the radio. However, they are the standard list, with zero being "open squelch" (no code). Here is a link to a Motorola manual which has a list of the PL codes in order on page 43. http://www.thekidshuttle.com/ABC%20Docs/CP100_Manual.pdf

On the T5720, another item to what for is the Qt noise filter. Be certain to set it to zero unless using the T5720 with others of the same model. It can also block transmissions. Here is a link to a user manual for the T5720 http://lib.store.yahoo.net/lib/starbattery/T56XXusersguide.pdf

Model SX750CR will send OK, can not receive.


There's no mute feature on 2-ways.

Will the 2 units work with each other? If so, then it could be an issue with the squelch codes.

There's usually a push button on those units that will "open" the squelch momentarily and you should then hear squelch noise and maybe get a green light to tell you squelch is open. If you have that and don't hear the noise, it could be a bad speaker.

Motorola FV500 2 way radio can send/cant receive


Do you hear the Beeps on the speaker? Check for the QT and the code squelch are the same in both radios, try to set code squelch in "0". Make sure that the radio is not receiving or the other one is not transmiting, with two radios will see the same.
