KX1 power mod

[Joseph Trombino, Jr]

I've recently seen reference to a KX1 power mod....where can I find this mod
and what version of the KX1 is it used on??

I checked the Elecraft site but didn't find it...did I miss something on the
site??

Joe,

The 'KX1 power mod' is available from Elecraft as PN E850230.  I could not
find it on the website, and I really don't know why.

The change is quite easy - just 2 resistors to change.  R30 increases to 33
ohms (from 22) and R11 is decreased to 4.7 ohms (from 10).  If you have the
1/4 watt resistors, you can make the change.  Someone who had excess offered
them on the reflector a day or two ago.

The change is needed for the KXB3080 installation, and has been shipped with
that option, but it can be installed on any KX1, even though it is not
required.

Do not exceed 4 watts for any significant length of time with your KX1, and
keep a watch on the temperature above the tuning knob if you are operating
at higher power levels.

73,

Here's the link to the KX1 Power Mod on the Elecraft website.  I
searched for it also and couldn't find it.  So I tried a Google
search, and there it was - very well hidden.  Don't know why it isn't
easier to find along with the other Elecraft mods.
