Yeasu FT2000 repair..
« on: November 17, 2022, 08:37:24 AM »

 :)Hi All, Im busy restoring an very much abused FT2000.
Previous owner had an golden screwdriver and turned ouput up to 200w, crapped out all tuner relays, and mashed all service menu params.
It is now working, but with one issue.
I have rebuilt the ATU main pcb with new relays, but on 7, 14, and 21Mhz the atu does not tune properly.
I have reset the couplers, but it seems the tuner control pcb is not telling main atu pcb to switch in relays for matching.
The cables are ok.
Any ideas?.

Also, is there no processor output level on this rig?.
Alc action seems excessive with processor on?.

Regards,
William, ZS4L / ZS5WC
