    I missed the start of this. Is it a handheld or a mobile? For a mobile, I d start by disconnecting pin 3 (PTT) and testing that it works when you trigger it

        Hooked the tracker 2 up to a Motorola M120 and it transmits except when I turn a corner, then it quits transmitting just for a second.
        Also run an OT1 with an Icom HT and swapped out the OT1 for the tracker 2, changed the jumper from HI to HT and it does the same thing. Seems to transmit all the time except when it samples, then it seems to pulse off just for a second.
        Seems that no matter what radio etc, it just transmits whenever it's hooked up and powered up.

        Config error? Is it transmitting valid packets or just keying down?

          Don, If the OT2 is always keyed, you will see red TX led light on. It really sounds like you have an intermittent short in the cable from the OT2 to the radio.

            Don,

            It really sounds like you have an intermittent short in the cable from the OT2 to the radio. If you have an ohmmeter, check for a short between pin 3 (PTT) of the OT2 connector and one of the other pins, especially GND on pin 6.

            Also note that the HI jumper is for high level audio output that you will probably need with the Motorola radio. The HT jumper is for those radios that key through the audio line and don't have a seperate PTT, such as the ICOM HT.

            Thanks Larry. Can t find any shorts in the cable. I just plugged in the T2 and the ACT light blinks, then the TX light blinks, then the RX light blinks.

              I just plugged in the T2 and the ACT light blinks, then the TX light blinks, then the RX light blinks. Repeats forever. Every time the ACT light blinks, the radio unkeys. It stays in this cycle until I remove the power.

              Turn off the power and exchange an OT1 for the T2 and all works normal. Radio stays off and the green light on the OT1 samples.

                Check the programming on the OT2 to make sure you don't have any profile switching going on. Sounds suspiciously like the infamous 'profile switching' endless loop problem where it is constantly flip-flopping between profiles and has 'Transmit when switching to this profile' is checked.

                    Does it exhibit this behavior without the radio connected?  Try just powering it up without the radio cable attached and see if you get the same results.

                      Well, the only suggestion I have left is to reload the firmware and let it load in the defaults to overwrite the current programming, power it up and see

                        Well, the only suggestion I have left is to reload the firmware and let it load in the 'defaults' to overwrite the current programming, power it up and see what happens. If it still does that endless loop, then it's pretty much assured there is something wrong with the OT2 hardware itself. If not, then the hardware should be good.

                        Next, if the hardware checks good, I would reload your programming, power it up, and see what happens. If it cycles then, it's in the programming somewhere. If not, I'm at a loss. Hook the radio back to it and see if the cycling starts.

                        Give that a try. Anyone else have other ideas if it still does that cycling after these two test conditions?

                        Does the same with or without the radio connected.
                        I only have power hooked up, nothing else.
                        Lights blink as before. ACT then TX then RX. Continuous in a loop.

                          Here are the results from your suggestions Randy.

                          New firmware downloaded and installed. (September 2 2009)

                          With nothing hooked up but power, the three lights blink just once when the power is applied and then nothing. No lights remain on.

                          Connect the radio cable then power up and the lights all blink once, as above, but the radio keys up and remains keyed. (Before, the lights would keep cycling and the radio would key on and off)

                          Thanks Randy for all your help. It is very much appreciated.

                          Don

                            Here are the results from your suggestions Randy.

                            New firmware downloaded and installed. (September 2 2009)

                            With nothing hooked up but power, the three lights blink just once when the power is applied and then nothing. No lights remain on.

                            Connect the radio cable then power up and the lights all blink once, as above, but the radio keys up and remains keyed. (Before, the lights would keep cycling and the radio would key on and off)

                            Thanks Randy for all your help. It is very much appreciated.

                                    I am using one of your cables Jason. The cable is OK. Works fine with the OT1 etc. Problem is the MOSFET is blown in the T2. Don VE7EDA
