Mike, Although the K2 manual indicates that the supplied plug is 1/8 inch, I measured several of the ones which I can easily insert into my K2 jacks and find them to be 0.137 to 0.140 inches in diameter - and that is greater than 1/8 inch (0.125 inch) and very close to 3.5 mm (0.1378 inches).
So you can buy whatever is advertized as 1/8 inch or the 3.5 mm size - as best I can tell, they are likely to be the same. 73, Don W3FPR > -----Original Message----- > > I know it's not 3/32", already wasted money on that size. > > Is it 1/8", 2.5mm, 3.5mm? > > Thanks! > > Mike, NJ2OM _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
