Hi Todor,
Well, I had experienced  same problem while ago. What I did, to clone with other GM300 and problem was solve. 
After that, you can write again with the right codeplug.

Hi, I used to have a code plug for an I think it was 8 ch UHF GM300 handy.

It's been a long time since I used it or the radio as the programming was dos based.

If I can find it do you think it would be of any use to you?

Hello all,


Accindentally I reprogrammed GM300 with wrong code plug.

Looks like this model was limited to less programms and I uploaded 16 programs into the radio .

Now , I can read content and there are 16 programs within but TX is inhibited .

Does anybody has good codeplug for this model:




Model M33GMC09CAA

s/n 159TYYF989


This is what I can read from it.

Codeplug witn only 4 program loc is good enough .

Thanks in advance.Regards,
