Hi JPK!
Working on my 573 module at the moment, all is well until now.
Now i'm confused that the 12-way rotary switch for the mid frequency has three central connectors (There's like
an outer and inner ring of connectors), but only one hole for the inner connectors on the PCB.
edit: I think as an electronics idiot - the actual switch is a 12-way three pole switch, but the PCB
is made to accept a 12-way one-pole switch.
Is this a sourcing thing? Can two of the three legs just be nipped off?
Thank you very much for clarification :)
Best, Martin

Sorry for the confusion.
You have to cut two pins, but not just any pins.
First make sure the switch is rotated all the way counter clockwise.
Then locate the stops which prevent the switch to rotate continuously (circled in blue in the picture).
The pin you want to keep is the one closest to the stops on the inner circle (circled in green).
Cut the 2 other pins on the inner circle (circled in red).

Thanks JPK!
If i may ask - am i right in the assumption that cutting any leg would have worked, but resulted in the wrong sequence of
frequencies? I tested the switch with a DMM, and each outer leg did make contact with all three inner legs when active.
Plus the inner legs had contacts between them as well.
Best and thank you for the fast help.

Absolutely right.
