Digirig Mobile
Digital modes interface for amateur radio combining audio codec, serial CAT interface and PTT control.
Key Features
- Combines audio codec, serial CAT interface and PTT switch
- Supports full featured CAT interface: PTT, bands, tuning etc. (not just VOX based PTT)
- Uses a single USB connection to computer minimizing the cables mess
- Serial computer aided transceiver (CAT) port can be configured for logic levels, RS-232, CI-V or TX-500 (learn more) (external link)
- Works with all major OS flavors: Windows, MacOS and Linux
- Permanently available independently from CAT port an open-collector PTT switch controlled by RTS signal of the COM port to interface HTs and mobile radios
- Auxiliary connection points to CM108 codec – for simple Allstar homebrew node builds
- Uses widely supported CP2102 serial interface and CM108 audio codec (generic audio device – no driver necessary)
- Small rugged aluminum enclosure ideal for mobile operations
- Interfaces the transceiver using widely available 3.5mm jacks (TRRS) for simple homebrew cable builds
- Isolation can be easily added using inexpensive USB isolator dongle
Notes regarding the interface configuration (external link):
- Audio + PTT are always available independently from serial CAT and they work for minimum required digital modes configuration with any radio
- CAT configuration is done with solder jumpers and can not be changed operationally
- Check the transceiver cables listing for your radio. The description will have CAT configuration requirements
- Learn more about CAT configurations here (external link)
