    I don't know yet if it work on a different channel using DPL cause its our first time here in my area using that kind of tone squelch. But for kenwood unit it works, that is why i got the tPL and rPL value. That value is only for kenwood cause in my motorola GP-68 the tPL and rPL is only up to 126.

    My other problem is that i have also another motorola GP-68 two way radio that i cannot unlock the said unit even i keep on long press the unlock key.

    Anyone please me with my problems.

    Here are some questions to help determine the problem:

    1. Does it work on any other channel using DPL?

    2. Does it Tx okay?

    3. Does it Rx okay?

    4. OR does it do neither?

I have a friend that he had also have a motorola gp68 but the problem is i cannot view the equivalent frequency even pressing the toggle light/enter and parameter for about 5 seconds. That is my usual oepration if i want to program a different frequency. I am helping my friend with his unit. How can i view the equivalent frequency on the channel mode without using the cable or by manual or any best way for me to understand.

Thank you so much for the help in advance.

Here is a link to download the user manual for the GP68

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.

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.

I just purchased two Baofeng BF 888s radios and had them programmed to our frequency here. They will both receive and transmit with each other but not transmit to the radios we already had. Any ideas?

Your radios could be programmed with subaudible tones (CTCSS) or digital code squelch (DCS) which the new radios do not have. They can be programmed for it, you need to find out what tone/code you are using.
It could also be that your existing radios are programmed for a "duplex" repeater channel, with different transmit and receive frequencies. The new radios might be on the "repeater output" frequency so they would not activate the repeater.
Both could be the case, missing tone and duplex frequencies.
I would check the programming of the new and old radios, especially for tone/code squelch.

Motorola gp-68 low battery beeps comes on too soon

I'm not sure that you can manually reset the low voltage threshold on your radio. Most of Motorola radio use programming software to turn on/off low battery beep and many other features. Everything is done by software.

Motorola gp 68

Batlabs at (Hand Held Radios) has the GP-68 users guide(Operation Guide), on the right side I think what you might be asking is in "Basic Operation 2", if not look into the Programming section below it.

Motorola T5210 does not receive

Are you sure that the radios share the same sub audible tone? Look at your owner manual for the section dealling with (and different people call it different things) ie: CTCSS, DCS, Private tone, code...etc... make sure that the tones are the same on both radios... this is usually the smaller number on the display.

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.
