Filter mod - need help


 

Hello all

My FRG 7 had a filter mod done at some stage in its life and I need some help to work out how to wire it up properly.? It's a long story, but while recapping the radio the filter, which was wired into the mode switch, came adrift.? Completely operator error, but of course now I am having trouble now working out how to wire the filter back in.? I have attached two photos showing the filters.
Any help appreciated.? Radio works well, but is now deaf.

cheers, Phil


 

Hi Phil,
It's hard to tell what's wrong from the two pictures. The only obvious thing is the bare copper wire not being grounded. It looks like it was under a screw head at one time. If that doesn't work pictures of the other ends of the four grey coaxes might help.

Thanks Roger

I should have explained that the pictures show the filters now removed from the board. Since my posting I have enlisted the help of a much more technically competent amateur friend and obtained some information from a member of the Australian Radio DX Club here.? We (he) is optimistic it can be sorted.? I shall post back if that all fails.

Many thanks for your reply.

Hi Roger

Just to close the circle on this.? My amateur friend restored the FRG-7 back to original spec viz the filter and discovered a dry solder joint on the IF board while he was at it.? Fixing that plus an alignment has it running better than ever.? It's great to have it back!? Thanks for replying.
