(Do not buy the RJ45 type) the VRM has no mic jack so it won't work. Cheap Chinese RIB boxes and cables can be had on ebay as well. Adapters might work.ĥb-Obtain MCS-2000 programming hardware.

It won't run under Windows 10 so break out your old XP box or a Windows 7 machine with serial port. We will need to HEX edit this to allow below 450 MHz frequencies. This will allow you to program your VRM-650 because a VRM-650 is an MCS-2000 with a different front panel. I can't post a link to it for obvious reasons but you can find it. I got mine for $10 each but the prices hover around that at the time of writing this.ĥa-Obtain Motorola MTS2000 CPS R02.03.00 software. Panik surplus has pallets of them on ebay. They are ultra cheap and work extremely well. For now I will assume we are going the 'hot spot' method for sake of simplicity and getting on the air. The RF duplexing antenna interface part is up to you if you decide to go the full duplex repeater method. Building a comple repeater up to the antenna is beyond the scope of this project but I will post info up to the point of interfacing. If you want to roll your own you can obtain two radios and use a duplexer. The easiest repeater setup is to go with a Yaesu DR-1X repeater but that's obviously not always practical. Do you want a simplex 'hot spot' or are you going to build a full duplex repeater. You will need to decide how you want to do this. There are other methods but this seems easiest to me. Again there are probably several but I like the Geaux Robot type.Ĥ- optional Nextion display to indicate calls, modes, talkgroups and other infoĤb- USB to TTL adapter to program the Nextion display. I have one but also have used the cheap Chinese clones that seem to work fine too for about half the price.ģa- optional housing for the DUE. Here is (I think) an original non knock off brand. I just like these Geaux Robot type open frame kits. ]Basic Pi at Amazon with power supply (need 16 Gig card though)Ģa - optional housing for the Pi. INADVM board (can be bought built instead of a kit)

Also, it uses a regular 9 pin serial type plug. It uses large through hole components and is easier to work on if needed. The original is called MMDVM but I like this one. Here is a step by step I will work on as I go and have time to add items here.ġ- Obtain a DVM board. This is simply amazing and can be done for about $100. I can pick up a DMR radio and key and be on the network, set it down and pick up my Astro Saber and instantly be networked on the P25 system and the same with the FT2D on Fusion. I started with a kit I bought at Dayton and now have 4 of them.Īnd one more I'm not sure what to do with yet. So I dived into the deep end of the MMDVM (multi mode digital voice modem) stuff that's taking off.
