Yaesu 6 pin mini DIN radios
A common standard for Yaesu radios is the 6 pin mini DIN plug.
The easiest way to get a wired 6 pin mini DIN plug is to buy a plug-to-plug cable, commonly available on eBay, for around £5-6, and cut it in half. Then you have two!
All you need to do then is work out (with a multimeter) which pin corresponds to each wire, and tack them to the pins on a 9 pin D shell plug as follows:
| Yaesu pin | Connection | DB9 TNC pin |
|---|---|---|
| 1 | Transmit audio | 1 |
| 2 | Ground | 6 |
| 3 | PTT | PTT |
| 4 | Receive audio (9600 baud) | 5 (option) |
| 5 | Receive audio (1200 baud) | 5 (option) |
| 6 | Squelch | Not connected |
Pick pin 4 if you'll be using 9600 baud, or pin 5 if you're using 1200 baud. You might be able to use pin 4 for 1200 baud as well.
This is verified to work with FT-450D and FT-1500m, and likely very many other Yaesu radios too. This also appears to be the same for the Icom IC-7000.
Yaesu 10 pin mini DIN
This is for the FTM-6000 and probably others.
Soldering a 10 pin mini DIN won't be any fun - instead buy a Yaesu CT-167 breakout cable.
Pinout (ref):
| Yaesu pin | Colour | Purpose |
|---|---|---|
| 1 | Brown | Transmit audio |
| 2 | Black thick wire | Ground |
| 3 | Red | PTT |
| 4 | Orange | 9600 baud receive audio |
| 5 | Yellow | 1200 baud receive audio |
