[ICOM] IC756 with InRad filter problem

[Gary Fiber]

If you used them in AFSK RTTY then you likely told the radio it had the 
SSB filters installed so the filters would be selected in narrow filter 
mode. If your memory is correct you installed the 400 Hz CW filters, in 
the menu the new owner will have to tell the 756.
Following the instructions on Page 55 of the manual he will have to tell 
the 756 the FL-100 is installed in the 9MHz position and the FL52A is 
installed in the 455 KHz position.
Follow Vladimir's manual link and he is quite correct on how many fooled 
the rig to get the desired filter effect.
