Comparison of Digital Voice Modes
Welcome to the K6JWN Digital Voice (DV) repeater! We are pleased to offer users two digital voice modes who are within RF range of the system.
MultiMode
Our Digital Voice (DV) repeater supports D-STAR and DMR. When idle, the repeater listens for incoming traffic on all 2 modes. Once a given mode like D-STAR is heard, the repeater gives preference to that mode for 20 seconds after a transmission, to preclude another mode from interrupting the QSO.
We recommend, when you are about to key up, first check your radio (S-meter or receive signal strength bars) to see if the repeater is already busy with another mode. It's quick and easy to glance at your radio before first keying up.
Frequency: 442.1875 (+5.0 MHz offset)
Usage Details – including how to send radio commands to connect to reflectors or talkgroups
Repeater Info
The K6JWN MultiMode repeater consists of:
- 2 Motorola CDM1550 radios (one for TX, one for RX)
- Repeater-Builder STM32-DVM v4 MultiMode modem. This board manages the different DV modes. It also converts digital data to analog tones to feed the TX radio, and converts analog tones from the RX radio into a digital stream.
- Raspberry Pi 3B+. The Pi runs the popular Pi-Star image which brings together a suite of open source programs written by Jonathan Naylor, G4KLX, including MMDVMHost and related programs.
