I have just repaired a FT-901dm from 1978/79 vintage, but it would seem the memory function is not working?.
I can store the memory, but when I want to recall the memory by pressing MR / TX or RX the VFO still seems to remain active.
Could it be that the WRITE line to the BCD counter is permanently HIGH, thus storing and relaying the VFO frequency directly?.
I had an FT-107m where this function worked just fine--any ideas what the problem could be?.
