Yaesu FT-1000MP Mark V No RX-TX Troubleshoot & Repair Part-3

In this video I troubleshoot some signal routing issues on the tuner board, try to identify a possible design floor and make a modification to the tuner unit.
I attempt to repair the TC-112NV reed relay. I also try to cover the basics of how the RF switching circuits work. This is part three of a series of videos diagnosing and repairing this radio. This is a component level electronic fault finding and repair video. Please feel free to leave comment as we’d love to hear from you.
