The Behringer can’t drive speakers, it wants at least 47 Ohms and puts out 124 mW per channel. If you want to power speakers, I recommend the $10 amp I use, it is 15 W per channel and runs from 12 V. The price varies, it is $8.50 today.

I have a simple splitter cable so the KX3 feeds my headphones and this amp. https://observer.wunderwood.org/2017/03/04/speakers-for-my-elecraft-kx3/ <https://observer.wunderwood.org/2017/03/04/speakers-for-my-elecraft-kx3/> Also, the Behringer HA400 is a 4-way headphone distribution amp for $25. Basically some op amps, volume controls, and jacks in a box. Other companies make pretty much the same thing for the same price. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Jun 20, 2017, at 1:55 PM, KENT TRIMBLE <[email protected]> wrote: > > Headphones and Field Day have been yoked since time immemorial.
