What is needed for the usage of a 9k6 transceiver

• Yaesu FT-8500
• Raspberry Pi (no matter what model, How-To is based on a RPi 3B+)
• A RJ45 LAN Cable
• A miniDIN 6pin Plug
• A 3.5mm stereo plug
• Adapter PCB (by HB9GSL)

Besides the FT-8500 every other 9k6 capable radio can also be used.

To make connections a little easier a adapter PCB is available (assembled except for the pin header). The PCB is available from hb9gsl@uska.ch for the price of shipping (limited quantities). For OMs who want to make the boards themselves the gerber files are available as well as the BOM. PCBs can be manufactured by JLCPCB (good experiences). All needed compontents are available at LCSC. This PCB can be used for all 9k6 transmitters that are based on UniPager.

On the PCB only the audio signal needs to be connected and the PCB plugged onto the PGIO port of the Raspberry. See photos:
