[Elecraft] [K3] Headphone Splitter/Amp

[Ron D'Eau Claire]

If there's plenty of audio, using a hard-wired splitter into an in-line
attenuator for each headphone will allow each listener to set the volume
independently without any additional equipment. 

Small in-line attenuators are available from a variety of sources for a few
bucks. One example is the Koss VC20 available for about $10 from sources
here in the USA

I used a Behringer HA-400 briefly for our FD effort and quickly replaced it
with a standard 2 phone jacks to 1 phone plug rigid adapter. I heard a very
loud garbled monitor signal when transmitting on SSB with the HA-400
headphone amplifier in use.  Our station wasn't grounded (at all), which
would account for this difficulty.  Next year I'll be more careful about
grounding the station.  

I think it'll work out well.  The two headphones we used were of different
makes and models, and of course one was much louder than the other.
