Just got K2 5848 complete. Everything looks good except the speakers (int or
ext) do not work. Headphones work great. I double-checked the wiring, and I

When I removed the speaker connector, I noticed
Copy of builders alert message.
We have a new Builder Alert, covering the wiring of the new type (RoHS

Tom,
If you are plugging the speaker into P5 on the CONTROL BOARD, it will NOT
work there.
Plug it into P5 on the RF Board and see what happens. If it still does not
work, you may have wired the external speaker jack incorrectly - it was

Miswiring the external speaker jack should not keep the speaker from
working, unless you reverse the copper (hot) and silver (ground) wires. The
new speaker jack reversed the position of the hot connections so if it was
wired according to the original illustration in the manual, there'd be no

I was working some cw on the k2 with the headphones. After I was done, I
pulled the headphones out of the jack and nothing was coming from the speaker.

Hmmm. The headphone jack in K2 4152 is intermittent also. I'm holding my
breath every time I unplug. Seems to be a problematic component, at least some
of them are. Maybe there was a bad batch?
Elecraft, is there a more reliable replacement?

Mine has a sticker saying Made in China on it. That pretty much tells you

The headphone jack on my K2 went bad (no speaker audio) early on and I
had to replace it.
The reason it went bad was because I was using an adapter to
I was using a small phone plug but it still failed after about a year. I
use headphones most of the time so never took out the plug for the entire
time. When I was going to use the speaker I found the jack had failed.
There are so many headphones around the house with 1/8 plugs that I would
It is a good idea to use a pigtail adapter if one is going from a small jack
on a radio to a larger jack for legacy headphones that you prefer.
Simply create a plug, pigtail of suitable audio flexible cable, and a jack
to accomplish the transition without an adapter putting heavy weight onto

The switch in my headphone jack fell apart within a few months even though
the jack body was still firmly in place. I do use a small right angle plug
plus quite long light weight leads to an inline 1/4in jack, and seldom
unplug the headphones. IMHO the jack is too close to the AF gain control,

Hi Geoff,
When you find a replacement could you please list it and its part
number on the Reflector? I would like to replace mine with one that is
far more sturdy so it will last longer than it did the first time.
