This will work with 3 repeaters models:

Midland MXR10

RetevisRT97S

RetevisRT97L

May also work with other repeaters if you know your repeater pinout, and you can make an adapter for it!!

This interface board is plug and play (NO soldering, wiring, etc.) ONLY for Retevis RT97s (NOT RT97 MUST be the RT97S model) or the Midland MXR10 or Retevis RT97L GMRs two-way radio repeaters! Those three repeaters have a DB9 on the side of them, this interface board plugs into the computer and repeater! So you can run programs on the computer like date & time, weather announcements, announcements, repeater ID, Zello and this can broadcast over your two-way radio air waves and/or over zello, using a computer ( laptop, mini pc,etc) or Raspberry Pi.

Please read the ALL the FAQ’s BEFORE BUYING on my forum NOTE: SETUP is the same as the RT97S/Midland mxr10 interface board:

Mic and speaker volume on the RT97L set to halfway level!!!

• This interface board will be installed in an enclosure/box! The box is for indoor use only, box has 4 mounting tabs, so box can be mounted! (see picture)

What you need to buy separately for interface board to work!!!

I highly recommend using USB sound card!! I have brand-NEW computers and the sound card in them didn’t have good sound quality for this setup!!

1). You need a computer (laptop, mini pc, etc.) that is running Windows 8 and higher for the software the interface board uses, This DON’T need to be a top of a line it can be an older one. The computer software that is need to be uses on the computer does NOT require a fast or a computer with high graphics!

2). Here is the USB sound card I use!! ( you must use this USB sound card!! any other sound cards may cause problems or not work at all!!)

3). You will also need a USB to DB9 adapter (unless your computer is old enough and has one, then you won’t need one)
