[Elecraft] [K3] [P3] IF Out / IF In Cable

[David Moes]

Yes there is a difference. But according to Amphenol spec sheet, "Two 
distinct types of 75 Ω BNC's are available, and both mate with each 
other and with 50 Ω BNC's. the difference is in the dielectric
This I doubt will be an issue at IF frequency.

This is also backed up in the highly reliable Wikipedia article on BNC ;-)
