[Elecraft] LINE OUT output too low?

I think you'll find standard, nominal "Line-In/Out" consumer levels to be 
referenced to -10 dBV irrespective of Z, where 0dBV = 1 Vrms.  This standard 
started with the old IHF, merged into EIA, and then somewhere along the way 
I believe AES became the recognized standard-setting organization in North 
America.  K9YC would know for sure.

-10 dBV is equivalent to 0.316 Vrms.  If we assume a worst-case 10 dB 
peak-to-average ratio (and probably a lot less depending on the K3's AGC 
menu settings), then the maximum distortion-free signal voltage handling 
required is 0 dBV or 1 Vrms or 2.83 Vp-p.
