RE: 9C Synth module frequency problems
I have the same thing and mine does the exact same as I just tried it. the module is not designed to operate on any channel above or below 11-60. which is the 72 mhz frecquency. the first dial is the 10 number and the second is the 1 number. so to select 57 for example you select 5 on the first dial and 7 on the second dial. I don't know why the pots are able to turned from 1-9 on both pots giving you the option to selext anything between 1-99
