[Elecraft] K3: simple headphone splitter

[Lu Romero]

A very elegant solution that seems to have become a defacto standard here in Tampa is the Behringer HA400 headset amp. Several years ago I purchased one for our local club, ther are now 4 there, plus it has also migrated to the St Petersburg radio club.  Simply plug a stereo mini plug into the K3 headphone or line out jack (NOT into the speaker out jack) and plug the othe side of it into a mini plug to stereo quarter inch plug into the input jack on the HA400.  Plug the HA400 wall wart into the power socket (or, if portable, two 9 volt batteries in parallel give 30-40 hours of operation) and plug up to 4 headsets into the HA400. Best of all, each headset has its own volume control on the HA400.  You can even feed a audio recorder to record both sides of the conversation if you turn monitor on in the K3.

I have used this headset mixer in my home station, in the club and even at high power Multi-Multi environments with a dozen kilowatt amps and never had any RFI.

$20 at any Guitar Center or on Amazon.  I've no pecuniary interest in the device, just that it works and works and works.
