Hello all, I have a icom 756 i preformed the MARS mod but it did not
work. anyone else have this problem?
Also i installed the 223 ssb filter. turned it on in the menu. it does
show up on the main filter menu.But you can not select it, is this
normal? Did a CPU reset. Even tried the Gen coverage button still will
not transmit MARS.
Everything else works as it should.
Any help would be greatly appreciated.

It appears that you may have made an error in the modification. I modified
an IC-751 where I had to cut a wire, and it didn't do it. I later
discovered I had cut the wrong wire. Made the change and all is well.

The IC-751 is not as sophisticated a unit as yours; the CW filter gets
selected by a front panel pushbutton. Perhaps there is an 'enabling' step,
such as cut a diode or something. Reread the instructions on installation
from ICOM.

If nothing seems to work, I would be pleased to help you with it; trouble
is, I'm in Los Angeles.
