KX1 VFO Issue

[ab2cj]

All:

I purchased a used KX1 and noticed that the rotary encoder behaves
erratically on occasion where it will momentarily fail to change
frequency when turning the knob.

There's some play in the VFO shaft which maybe the cause of the problem.
The serial number is 666 which seems like an early model and I was
wondering if there's a history of a bad batch of encoders shipped at
that time?

Thanks,

Tony -K2MO

All:

Anyone have an idea for an adapter that would allow the use of the KX2
paddles on the KX1? I have the paddles that came with rig, but prefer
the adjustable KX2 design.

Searched the web for alternatives, but there doesn't seem to be any
retrofit paddles that will attach to the KX1. I prefer the bolt-on
option rather than attaching a key to the side of the rig with velcro.

Thanks,

Tony -K2MO

Tony,

The play in the VFO shaft is an indicator that the KX1 you have has been
well used for some time.
The easiest solution is just to replace the encoder.

I have repaired many KX1s, but only a few well used ones have had
encoder problems, so I don't believe there is a "bad batch of encoders"
in the KX1 history.  Yes, yours was an early KX1.

Look up the part number and description in the KX1 parts list and email
it to [hidden email].  You will receive a return email with the
cost, and then you can order one using the Quick Order form on the website.
