[KX3] New Product: SPX3 External Speaker

[Robert J. Morris]

SPX3
Here is an update to the powered external speaker for the KX3 I've been
developing, named SPX3. It has required a lot of patience waiting for
prototype circuit boards and sheet metal enclosure parts to be
fabricated. Refinements are still in process. At any rate, here is the
latest.

AESTHETICS
The speaker is designed to match the overall look of the KX3 and PX3,
and accept similar third-party panels and covers as for the KX Line. The
folks at SIDE KX are working with me on this. Presently, it uses the
same feet as the KX3 and PX3, and the same style rear leg as the KX2. It
is the same height and depth as the KX3 and PX3. There is one power port
for charging the internal lithium battery, and input and output stereo
jacks. The speaker is mono. The output jack redirects the right channel
from the stereo input for a second speaker, just like with the Elecraft
SP3 and other similar external speakers. The speaker is amplified.

SPECIFICATIONS
The SPX3 amplifier puts out a maximum of 5W into a 10W speaker driver,
and is about as loud as any external radio speaker gets. Volume is
adjusted by the KX3 and by the volume knob on the SPX3. The volume knob
also turns it on and off. It plugs into the KX2/KX3 PHONES jack. There
is a built-in band pass filter to reduce noise and improve the listening
experience.

Just like the KX2, KX3 and PX3, the SPX3 is not waterproof. So, don't
drop it in a lake. It will handle all conditions appropriate for the KX
Line, and is meant for indoor and outdoor use.

You'll see the speaker is not a polished finished product yet, as it's a
prototype spray painted by hand without labels. A power on LED will be
added to the final product.

Please note, the KX3 in the photo is only to demonstrate the speaker.

I was horrified to discover the Elecraft mail server mangled the picture
URLs, and added old URLs at the bottom. Please try these, without
quotes:
