Instructions for connecting radios, repeaters and AllStarLink interfaces including the RTCM, GPS, URI/URI X and like devices.

GPS

Motorola

CDM

CDMs make great nodes. This eBay reseller has very nice cables. Use to connect to URI or RTCM.

CDM Cable from Kurt Meltzer ex-WB9KNX, now KC4NX - Cable 83 has only one output to use for either COS or CTCSS. Use another cable if you need both COS and CTCSS.

MTR-2000

Quantar

The Quantar can be tricky to interface as it's extremely programmable and you will need a wireline card for I/O connections. By default the I/O will not work unless the "wildcard" table is programed. This wildcard table is Boolean logic of interrupt states in the radio, is extremely flexible and frustrating to debug. It's a base station in it's own class.

Front of Quantar and controller

Note you will want to use BEW mode on the RTCM if using the RTCM do squelch.

Syntor X

The Motorola Syntor X with an Xcat installed makes a great frequency agile remote base. For more information see this Syntor Xcat page.

VRM-850

Kenwood

TKR720/820

Connections to: PTT, COS, RX audio out and MIC audio in

TX/RX board, MIC audio input, pins 4 & 5: floating ground, must not tie to any other ground! Some installations may require a 10dB, resistor L-network consisting of a 4.7k and 470 ohm resistors. The 470 ohm resistor connection across pins four and five, the 4.7k resistor is soldered to pin 5 to which your TX audio from the URI will connect to.

The MIC audio gain, deviation, and balance adjustments are *very* sensitive!

- RA-35 without TX adj. trimmer pots: Using a service monitor with deviation metering, start low and work your way up to 3KHz deviation with 1KHz tone, generated by simpleusb-tune-menu. If enabled, *904 turns this tone on and off by command, ie, no tone time-out as in simpleusb-tune-menu.

TKR750/850

Using the Masters Communications RA-35 or RA-40 radio adapters with the TKR750/850

Repeater Controller

An example of using RTCMs to replace 420 links

Spectra Engineering

  • MX800 Base station - Bryan Fields, W9CR has a complete setup guide for the MX800 Base station which includes fallback to the built in controller and an audio delay module.

Tait

URI / URI X

The URI is manufactured and sold by DMK Engineering.

RA-40 / RA-35

The RA-40 is the latest version and is sold by W3KKC. The RA-40 includes audio output level control potentiometers and much more.
