[Elecraft] Powerpole police here....

[Joe Subich, W4TV]

Charlie,

I don't have a set of calipers or mikes handy but grabbing a steel
rule and measuring three 3.5mm plugs at random off my bench - they
all look to be 9/64 (0.14").  I do know that I've thrown out all of
the 1/8" plugs I had because they make such bad contact in equipment.

I don't know of any amateur manufacturer that is still using 1/8"
jacks.  They can be damaged if one forces a 3.5mm plug into them.

73,

    ... Joe, W4TV
