If it has a 515k FLASHROM inside,it is possible to flash it into a GM340.
Before you do something,read and save the tuning data and write down the temperaturecompansation values.
Always program the new codeplug,before you flash it.

I've programmed many tens of Moto GM series radios, and never had a single issue.
Recently, this happened with a set I bought on "a well known auction website".

The radio has been pressed into service as a single channel RoIP link, so not really a problem as such, but it would be nice to know if this gets resolved, as I couldn't work it out.   Cry

Hi Jon,

Wow, this was a long time ago. The original post was almost a decade ago!
I can't remember what happened with my problem in the end, but I've run a number of GM series radios in the meantime, so I must have sorted it at some point.

As for your problem..
I strongly recommend using line in audio rather than microphone audio. I avoid any amplification if possible to try and keep the noise down.
Try using Pin 5 (Flat TX audio). Input needs to be about 150mV for 60% deviation (from Moto datasheet).

Also, I refuse, point blank, to short ground connections between devices after killing a really nice MP3 player during testing.
After the above happened, I put 1:1 600ohm transformers between everything, and use either opto-isolators or relays for the PTT. This means that the radio has absolutely NO electrical connection to the "other" device (PC etc).
The transformers also alleviate impedance issues.

I'll keep an eye out here, but if problems persist, contact me on any of the details below and I'll have a closer look.

I've been building interfaces for people on an ad-hoc basis for somewhere in the region of 15 years. This has started to wear thin, due to the problems inherent with veroboard designs.
I'm moving to a more reliable design with the build process documented here: https://www.facebook.com/voxlinkroip/
The above is a work in process!!

Hi All
I've been working with Motorola equipment for many years.
Now I've been asked a question I'm unsure about.
Can a 4 channel standard CDM750 be flashed to become a GM340 so a standard CPS can be used for programming?

Best Regards
Steve

B or C revision cable, not A

Quick query about cable compatibility, are DP3xxx cables compatible with the DP4xxx radios? I've some DP4400e units that I need to program, just want to make sure I get the right cable.

Guys you are magnificent.

Andreas,

I did what you suggested. Phase 3 codeplug upgrade, but I needed to leave all check boxes checked by default ("Write hardware codeplug" and "Write application code plug). Installation completed without problems.
Added regional ID, as you suggested
Then I assigned serial number using Professional Tuner. With the same program I checked temperature compensation value.
The only other thing I did was programming frequencies.

It is working like a charm, for now.
I would like to thank you all for your contribution.
It was privilege "working" (by working I mean listening and following) with you. Now I'm richer for one more experience and few more friends.
Thank you!

Sometimes, the tuning datas are part of the problem, as they could be corrupted too.
If the steps described by Andreas don't work, try with another working tuning set (radio will need to be aligned).
But usually it works well !

Yes,thats it.
If you receive nothing and the red LED is not blinking,I think the radio must completely aligned.
Before you do something,read and save the tuning data.
Donīt set the radio in flashmode for this:
Run the lab upgradetool and search for a codeplug,thats match to your Tanapa.Program it as Phase 3 without enableing something more.
Set the regionalcode to emea.
Read the tuning data and set the serial number.After this load the tuning data file and program the radio.Read it again and check the temperature compensation values.

Andreas
