Mods to a FT-4700H to allow it to expand the bands.


 

I am trying to help another ham friend out.? He has a FT-4700H that won't cover all the US frequencies.? There is a post in the cloud for doing the modification, but it is unclear as to what you actually need to solder.? It says locate jumper 1,2,5,9,10,13 and short them with solder on the control unit.? Well there are no jumpers that are available to bridge.? The only thing I found was a IC that has 14 pins (Q5) on the board that you could short the pins too.? I have a bad feeling about this and wonder if anyone has addressed this on one of these boards?? They don't give enough detail about where this is on the board.? Waiting for more input on this subject.

Thanks
