President Mckinley Microphone

[whiteastro]

Was wondering if anyone knows of a modification to a stock McKinley mic. to improve it's performance. I've had this radio for a couple months and have made no DX contacts with it yet and yes my SWR is fantastic and I'm driving a KL 203P and have tried different things to make a contact to no avail. Looking at the port holes into the mic. they look deficient and wonder if anybody ever opened them up for clarity purpose. I've also noticed when I send a tone to my radio mic from my Dosy TRC 3001-S meter to read the frequency read out I have to search for the sweet spot on the mic to get the correct read out on 38 LSB. Before I start taking the mic apart to check it out I figure I better ask the members in here first. I like the channel up & down buttons on the mic so I really don't want to replace the mic if I don't have to. HELP any suggestions ! Thanks

What I and a few others here did was to make a small hole over the element. You should remove the element from its spot, drill the hole, and reinstall. YMMV

Thanks for the tip, I was sure someone did some mod because the factory mic looks deficient. May I ask what size hole?

Have a look for those earlier threads.
Other tips on use may apply.

Thanks everyone for the valuable info, I always enjoy learning. I wish I got back into radio a lot earlier so I could be more advanced but better late than never !
