GP300-5T

[frenki05]

Can someone explain to me how to solve the problem. I have a GP300-5T that I have several times previously programmed with Radio Interface Box RLN-4008, now when I again want to insert a frequency, I can not not read the radio GP300. Is there a method to reset the station, or to somehow reprogram. Did someone turn can be inserted to upgrade firmware.

I ask you to tell me what to do.

Thanks a lot

Hi,

first of all, check the correctly supply of RLN4008 rib box.

Now, try to write codeplug into radio. They haven't LAB RSS to this radio ,the only way is write codeplug. This problem, that can't write, or read with some error, and they happened to me frequently.

I will give you my codeplugs of 8CH/UHF or 16CH/VHF 5T GP300 Radio.

Regards.

Santi.

If you sure that your interface box, com-port and programming cable are ok then try to clean programming point (BUS+, SCI) of your GP300-5T with a contact cleaner or alcohol or maybe little sctraching with a screwdriver. As you know, programming point is a little copper surface which located near positive battery contact. Once, I solved a programming problem by this way.

Btw, does your radio work properly beside programming issue?
