Yaesu FTM-200DR
The FTM-200DR is the single-receive sibling of the FTM-300DR — a dual-band C4FM/FM mobile. Interface it the same way, via the rear 10-pin mini-DIN DATA port (use FM for analog ORLP). Audio & PTT: 10-pin mini-DIN DATA port — Pin 1 discriminator audio out, Pin 5 audio input, Pin 4 PTT (active low), Pin 9 ground. Use a Digirig or SignaLink with the matching FTM cable. CAT: Drive PTT from the DATA port; do not depend on live USB CAT keying. Bluetooth: Built-in Bluetooth is for a wireless headset, not node control.
