Legible FT-847 Circuit diagram


 

The FT-847 circuit diagrams found on the internet are not really legible. Where to find a good diagram?

Not sure where I got this one, but it does blow up nicely.

The attached circuit diagram from VE3FFR is the best I've seen so far. Thank you. Now I can read component names and order spare parts. 73 OZ1BXM?


 

I do have the service manual PDF. But the circuit diagram is difficult to read, especially component names and values. 73 OZ1BXM


 

I have an FT847 and I expect the circuit diagrams. I can (when I locate them) scan them. Why would you need them? Have you lost yours? i will not look for them unnecessarily. I am not even sure they are there.

I've lost the original manuals and the circuit diagram. However, "FT-847_Schematic.pdf" provided by VE3FFR is excellent, and all I need for now.

I need a legible circuit diagram because there is a problem with my FT-847 transceiver: Low RX Sensitivity on 144 MHz. I'll share with the group if I can solve the problem.
