After downloading the service manual and following the schematic I found it to be a failed shift register that switches filters, TX/RX, etc. Not having the time to get a new part I removed the IC, installed a toggle switch and manually switched between VHF and UHF as I needed. It's still this way, the Franken-817. I only paid $200 for it used so I'll probably replace it before investing in a proper repair.
