Digirig Mobile is a digital modes interface for amateur radio.
This listing is for revision 1.9 using TRRS connectors. Backward compatible to rev 1.6
- 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)
- 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
- axillary connection points to CM108 codec – for simple Allstar homebrew node builds
- uses widely supported CP2102 serial interface (latest driver) 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
- growing collection of pre-made cables including popular Icom, Yaesu, Elecraft, Baofeng, Xiegu transceivers
- isolation can be easily added using inexpensive USB isolator dongle
Notes regarding the interface configuration:
- 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
This listing does not include cables. The USB cable is a standard USB Type-C cord which must support both power/charging and data.
Please refer to the blog post for configuration information and schematic containing the pinout reference if building homebrew cables.
