[INRAD] Filter Board

[N5IET Bob]

Well, I got it working. 

I had to unsolder all filters and reinstall and now all is
well.

I bought this board used, so I will say this, I have been
Doing electronics for a long time and unless you
have at min a couple of years of quality soldering
experience behind you, get someone who does to work on
these boards for you (especially if you are taking the
filters off the board).

This switchboard is really nice BTW.

Works like a champ on the dx pile ups. Now I have to turn
it off to find the pile up and turn it back on when I get
there. Hi Hi

This is great. 

Thanks INRAD for a job well done.

 73 fer nw,

Code may be taking a back seat for now,
but the pioneering spirit that put the code
there in the first place is out front of it all.
