[Elecraft] LINE OUT output too low?

[André Santos]

Thanks Don!

I was planning to make the audio mod anyway. It might help to increase the
output level even a little bit.

The actual output level (or amplification) for some reason is well below the
standard for line outs. Elecraft should address this problem.

Otherwise, I think the K3 is a fantastic transceiver. The best one I have
ever had.
