2018-09-13 Missing bit for the HF amplifier: the PA control cable
The HF linear amplifier I bought had one missing link: the control cable to signal when to start transmitting. I first looked for such a cable at Hamshop but the cable was not available anymore. Further searching found the right cable at 8 pin linear amp switching cable for Yaesu FT-817 FT-857 FT-891 FT-897 FT-991 - TechnoFix UK and ordered it. It came in, so time to test it in the upcoming weekend.
