[Elecraft] two k3's on the same band

[Al Lorona]

Jim, I think you may have answered a question that's been on my mind for years.

Some time ago an advertisement for coax cable in QST said that a certain cable 
had "80 dB shielding". I had never seen a spec for this before. Could they have 
been referring to the leakage from inside to outside; outside to inside (as you 
were describing); or both? Or something else?
