Information and Modification Articles:

MSR2000 Information, Modifications, Photos, Hints, Tips by Mike Morris WA6ILQ
There is a lot more MSR2000 information here.

Channel Elements for the Mitrek or MSR2000 by Mike Morris WA6ILQ

Conversion and interfacing of an MSR2000 station to an external repeater controller by Henry Wingate K4HAL
While the author used a CAT200B controller, the information applies to most other units.

A status display for the MSR2000 station by Henry Wingate K4HAL
Put that empty slot to work. A few LEDs can go a long way towards diagnosing control problems.

Connecting a CAT250 controller to an MSR2000 repeater by Nate Bargmann NØNB
The author describes the conversion and interfacing procedure for the WØDOD repeater.

MSR2000 Conversion by David Stanford K7IOU (offsite link)
Yet another group's conversion project using a CAT250 controller.

Modifications to the MSR2000 cards for the VE6NHB repeater by VESBS (offsite link)
Again, a few LEDs and switches can make all the difference. Several cards were modified. Full documentation is provided.

Documentation on the TLN6721CDX TX Alarm Card

In-cabinet Repeater Controller for the MSR2000 Station by Eric Grabowski KH6CQ. 260 kB PDF
Eric mounted an NHRC-4 controller onto a spare card that plugs right into the MSR2000. Very clean; very neat. Well-done article.

Adding an ID-8 to a MICOR or MSR2000 Shelf by Jerry Matthews WAØUZI
This article also applies to the MICOR and Motrac/Motran series of stations with plug-in card shelves.

Adding an ID-O-Matic to an MSR2000 Station by Eric Grabowski KH6CQ. 278 kB PDF
Eric added an ID-O-Matic II Morse identifier board to an MSR2000 squelch gate module and mounted both boards behind a double-wide front panel fashioned from an MSR2000 Line Driver module. Another well-done article. More info is available at the link below.

The ID-O-Matic kit by NØXAS (offsite link)
Another low-cost CW ID solution that can be added to an MSR2000 repeater.

Detailed audio path diagram for the MSR2000 Station by Eric Grabowski KH6CQ. 35 kB PDF

Running D-STAR on a Motorola MSR2000 VHF Repeater by Ron Wright N9EE.
A D-STAR repeater controller can be easily added to an MSR2000.
