Portable Repeater Controller

This microprocessor-based Portable Repeater Controller was designed to quickly build a fully functional repeater 'in the field' in less than no time. Due to its universal design it can be used all the way from classroom instruction to 24/7 repeater operation. A fully functional amateur radio repeater system is created by just connecting two radios, an antenna, a power supply and optionally filters.

The Portable Repeater Controller is designed by Leo PA0LEZ and Ivo PA1IVO and is made available via Emco Electronics.

Configurability and remote control

Almost all repeater controller settings are user configurable, which enables repeater builders to create a fully tailor-made system, based on the needs, and of course, personal taste: Configuration settings can be made in four different ways, where the combination of these four configuration options creates a flexible and versatile system:
  1. With a PC connected via the serial interface. By storing different configurations on a PC, different repeater configurations can be activated with just a few mouse clicks (available in version 2).
  2. DTMF remote control via the main receiver input.
  3. DMTF remote control via a sub-band receiver input, creating a private configuration channel. Up to four controllers are addressable and can be connected to a single command receiver.
  4. Locally on the controller, without any additional equipment, by using the LCD and the high quality navigation buttons. In this way, last minutes changes are possible anywhere, anytime.


PCB width x height: 162.8 x 75 mm.

Licence requirements

Please check your local amateur radio regulations if (additional) licences are required to set up your repeater system.

Instruction Manual

Firmware Version

Currently the Portable Repeater Controller contains version 1.4 of the firmware which includes all functions described here, but without interfacing to a PC for monitoring and configuration. Version 1.4 does include the free firmware update option. In version 2 of the firmware the interfacing to a PC will become available. Owners of a Portable Repeater Controller will be informed about the new firmware version 2, which will be free and user upgradable with the free Windows software tool.

The new firmware version 2 is currently being tested and is expected to be available in March 2018.

Firmware Update
