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.

Motorola software is available by subscription to authorized dealers and as needed to certain entities. The software is proprietary to Motorola and cannot be sold by dealers. It would be best, and least expensive, to take your GP328 to your nearest dealer and have it programmed.

SOURCE: Cobra PR4750WX - how do I adjust squelch?

You are right there is no adjustment. You can however turn the squelch off and this maybe what is happening to you.
To turn the squelch off you press and hold the button that is just below the push-to-talk button for at least 5 seconds.
To turn the squelch back on, you either press (less than 5 sec.) and the same button or change channels.
When talking with a specific party or group, you should use the tone coded squelch (CTCSS) and that will mitigate the noise if you are not already doing that.

Continuous green light at GP-2000 and hissing sound from speaker


Have you adjusted squelch threshold. Green light indicated signal received with noise, squelch will adjust the threshold so light goes off except when a stronger signal is detected.

Portable motorola gp 340 can receive but cannot transmit


Don't know your capabilities but if it were me I would open the phone and check the contacts for transmit button. Sometimes contacts get corroded and need cleaning or it just may be no connection at all and a adjustment of the contacts will resolve the issue.

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

Did the radios previously work together? If so, you have one radio in need of repair.

If the radios are new to you, and you do not know if they previously worked together, it could be a simple programming problem. Take it to your local Motorola dealer to check the programming.

One simple test to see if you have one with PL and one CSQ, is to press the monitor button and see if the two radios can communicate when they are in open squelch mode. (The monitor button will be one of the side buttons near the PTT.)

How to set squelch on a motorola t73xta7ta7bk 2 way radio


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.
