MCS2000 Interface Cable.

[Luish19779]

Hi everyone and Thanks for always support me with your knowledge. I want to build a repeater with MCS2000 UHF radios. I don’t want make a mistake on this. Are this cable the right one? Because I know is use for Pyramide mobile repeater too.

Thank you guys.

You can use that cable but will need one for each radio. I assume your using the mid power model. You can find the plugs and pins cheaper and spin your own cable. All you need is PTT, COR, Discriminator, Ground and Mic Hi. In the end depending on what your doing its 3 wires to each radio. (RX Radio - COR, GND and RX Discriminator, TX Radio - GND, PTT and Mic)

What do you think about this cables?

[gortex2]

They will work fine. 

 

[Luish19779]

I think this is the cable you talking about…

the thing is I have to see a video etc to do all this. You know..

[gortex2]

What are you using for a controller ? That may help deciding which cable to use. As said for a basic repeater you can use 3 wires. Done that on many GM300/Maxtrac radios over the years. 

[Luish19779]

Right now, Nothing. I only have Radios, Antenna , cables  power supply. Just the simple. That the hard part for me, because I never built a repeater by myself. I think I need like a ( LIST TO BUY) I got 4 radios. 2 MCS2000 40-50 w and 2- XTL2500

So why not just get online and grab a UHF repeater premade. In the end it will be simpler and probably cheaper. You will still need a duplexer for either a true LMR repeater or a home built one. 

I don't know anyone that sells a premade cable and controller for the MCS. I'm sure you can find a controller and use some of the above cables but if you dont have the technical skills to solder and assemble complete units are easier. 

There is alot of info on the MCS here - https://www.repeater-builder.com/motorola/mcs2000/mcs2000-index.html
