APPENDIX D – Typical Hardware Configurations

Basic micro2R setup

Special notes:

●

The CAT port of each radio is connected to the computer serial port or USB to serial port adapters.
Use appropriate level converter as necessary

●

3

rd

 party band decoders used for automatic Antenna and BPF switching must use the Yaesu TTL

band data format.  

●

For digital mode operation, the constant level audio output from each radio must be isolated using
audio transformers.  The left radio (Radio 1) should be connected to the left audio channel (tip and
sleeve) of the sound card line input.  The right radio (Radio 2) should be connected to the right audio
channel (ring and sleeve) of the stereo sound card Line input.
