IF Unit circuit

 

Hi, guys,

I need an IF Unit circuit without black labels indicating voltages and signals.

These labels are over the lines of circuit and I cant to follow the lines of this Unit.

Thanks.?

Hi Jose,

Use the SECOND set of schematics in the FT-980 Technical Supplement, which can be found in the "Files" section, not the debugging/alignment schematics which are earlier in the Supplement.

For the IF unit these are located on pages 182 and 183. I usually print both pages out on 11x17, and then align and tape them together.
