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. 73 Lu Romero W4LT (currently /YO2) I'm using an IPad. It decides how things should be spelled. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
