HELP ICOM 756
 

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.
