Hi, could anyone give me some information on what the C MSG feature is for on a Sinadder Model CML-1. There is an on off switch on the front panel for this but I don't know what it is for.
Also, if anyone has a file for this particular Sinadder I would sure appreciate obtaining a copy. I think it is basically a Sinadder 3 but am not sure of any differences in it. 73, Bruce, VE1II
