I use this same performance board in a IC-756 and have no problem. Do 
you have the yellow and red wires connected in the right spot? I use 
INRAD IC-765 performance enhancement boards and roofing filters in 
experimental modifications and except for gain adjustments on the 
feedback amplifier due to differing loads presented they are a working 
thing. The easiest way of checking your mod install is by reconfiguring 
the rig to original and measure output on affected bands. It may be a 
marginal rf blocking choke, L3 in the performance board also because 
this would show up at lower frequencies first. I hope these comments 
offer some help.
