Tnx for reply.
No others, only those two.
Btw. I have Ft-980 Technical Supplement and I have measured values on the vco/pll and vfo units. BUT.
Don't know where to start. In how many places the frequence is regulated and expecially those hz/ 10 hz steps.
What to check and in what order.
Changin components, etc.
