With all of the jumpers on, the inductors are bypassed and
the variable capacitor is in play, removing it's jumper takes the cap out of circuit.

Ats3B.1 as kitted by KD1JV but with my modifactions. The
attenuator mod is taken from OK1IF as posted on the yahoo user's group
for the radio. http://groups.yahoo.com/group/AT_Sprint/
. I changed the value to a 1K pot because I had one, but then I
liked it better
anyway. I had used a 500ohm pot on my original ats3b. I
also switched sides for mounting the band modules to the top side of the
board. I won't be mounting in a standard Altoids tin, so this is
more convenient for my purposes.
