Headphones and Field Day have been yoked since time immemorial. The
K3's ability to output its audio into both headphones and speakers
simultaneously has been a boon to those FD sites that encourage
visitors. It permits the operator/logger to use headphones while
visitors can monitor the action through speakers. The problem lies in
the volume levels that each of the participants require (or don't
require). This is especially true when multiple transceivers are
occupying the same tent/trailer/room, etc., and each have their own
group of listeners. Cacophony is not the goal here.
As veteran Field-Day clubs have discovered over the years, a valuable
accessory is a multi-outlet headphone-amplifier with individual volume
controls for each headphone. For several years we have used a Behringer
Amp800
(https://www.amazon.com/Behringer-AMP800-Four-Channel-Headphone/dp/B000KU87SM)
at our CW position. Lately, we have also been using a Rolls HA43
(http://www.rolls.com/product.php?pid=HA43) which is smaller and easier
to operate. Neither are bothered by stray RF.
I have no vested interest in either. There are similar products under
various brand-names. The Behringer can be had for around $70 and the
Rolls for $50 from numerous online vendors. The Behringer only accepts
1/4-inch phono plugs while the Rolls has dual input jacks to accept both
1/4-inch phono and 1/8th-inch plugs. This is another reason I like the
Rolls as no "tweenies" (adapters) are needed.
Uses might include . . .
A neophyte with an unconnected laptop, wearing his own headphones,
entering call signs/exchanges into a practice logging program without
disturbing the main operator. Or the next shift warming-up before
assuming the operator's position. Or someone merely wanting to
seriously listen for a while without being bothered by the inevitable
traipsing in-and-out of visitors, kibitzers, the lost, the lonely, the
huddled masses yearning to be free.
Both of the above units accommodate up to four headphones.
