Good day yall!
This radio has very Little info on it or where i can get a programming cable or build one for this radio, i have looked in the rr forums, but shows for the handheld.
I need some guidance on this, i have reached out to midland (here in kc, but they seem to have moved away from part 90 radio)
so i am reaching out to you guys and maybe move me in the right directions.
thanks in advanced

DOS ONLY SOFTWARE 9 PIN SERIAL ONLY
If you do not have an old 1980's DOS 6.0 386PC you are going to be out of luck.
There is a Rubber Boot on the top of the Platter near the front of the Platter.
I still have in my Shed a VHF and an UHF version with PROGRAMMING CABLE and SOFTWARE have not seen then in 30 Years.

In the 80's Icom made the 16 Channel Programable Portables IC-4AT Same Radio as Midland 16 Channel Portables.

riccom, were you able to find the schematic for the programming cable. I have been looking for this cable as well. I did manage to find a schematic for the cloning cable. If anyone has the pinout for the microphone jack, I would greatly appreciate a diagram or description. I am going to build my own cable. Thanks

Does any one know if this radio can be made into a repeater? I am thinking about purchasing two of these mobiles to build a cheap repeater. Any and all help would be appreciated!

The attached test setup shows a serial port on pins 2&3 on the microphone port, RS232 levels so external level shifters should not be necessary.

The Midland SynTech 3 is a rebadged Aselsan 4700 series mobile radio.

Good morning folks:
I have found a friend who had one made, it was kinda trucky, but i did get it to work, and this radio, is awesome, for vhf p25 and its not a tunking radio, but will follow it, if done right.

As for being a repeater, you could, but I am not sure, there may be some issue with audio. Thats just imho.
