[Elecraft] K3: Recording from LIN OUT

[Paul Christensen]

When I see the term "line" used in conjunction with either RCA or 1/8-inch 
TRS jacks, I've already decided that they're really referring to the old IHF 
consumer standard where 0dB is -10 dBV, referenced to 1V, irrespective of Z. 
Plenty consumer equipment still uses the term "line" to reference the IHF 
level so, I'm not sure if there's much value in calling it something else 
when the K3 is used by most ops to interface the line jacks into 
consumer-level equipment (e.g., PC sound card) -- with a minority of users 
interfacing into professional audio equipment.
