CHIRP

This is a duplicate and I cant find a place to close it.

This one isnt the duplicate, the other was flagged by someone else.

I took a look at the files in a hex editor and this file is structured very close to the CS-700 file. I've been able to get a cs700 parts extract and pasted into a file the software and radio tolerates. The GPS details toggle a few of the bits ending at FF FF FF FF 00 00 FC where GPS sewnd and rx are set and FC is FF where the is not set, same as the CS700 plug. I've been able to get the zones, channels, and contacts transferred from a CS 700 file into a MD-390 GPS model. I've only taken the Contacts, Zones, and Channels sections and replaced the bit into the file I extracted from the initial radio file.

Can you post the .rdt here?

The CS700 ARES codeplug file was my starting point... The TYT I started with reading from the radio fresh out of the box, and the TYT after some hexedit and alignment and pasted, hoped for very little list length checking or anything else... And, the TYT software seemed happy, I tried writing, and the radio seemed happy... Being very new to DMR I'm still trying to figure all the channels and talkgroups and user activated activation...

You lost me... Were these generated by the official software or not? Before I study them I want to make sure there are no errors or incorrect assumptions in them.

This was a read with official software. If you've looked at CS700 files , you'll see this one is very similar. Looking at the interface aside from some minor screen window sizes and GPS setting not in the CS700 software they are very similar.

TYTMD-390 20160906.rdt is a read of the radio directly out of the box

This I assume was created with the official software

CT CS700 Code Plug 22.rdt was generated by a member of the local ARES club for the CS700

This is my merge of above file with the 1st file

TYTMD-390 20160906ManualWZonesChannelsScan.rdt is my hex edit of the ARES CS700 plug into the factory read file above, so ignore this one if you want to avoid any potential errors. I copied the zone channel and scan sections from the CS700 and pasted them at what appeared to be the appropriate offset. The software and the radio seem happy.

I can look over the screens between the cs700 and md390 GPS for differences.

So far...

General Settings Add on the CPS MD-390 w GPS
Radio Program password, looks for max 8 characters
Back light time: Always, 5 10, 15
Set keypad lock time: never, 5, 10, 15

Intro screen section
Intro Screen: Picture, char string
Intro Screen line 1: 20 chars
Intro Screen line 2: 20 chars

Let me know if you need the offsets for any of these of set values and send the before and after files

In channel info

3 fields are additional:
Send GPS Info: check box These are both in the FF that became FC
Receive GPS Info: check box

GPS System: none, 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16
