K3 meter indication problem

[Lee Trout]

I am having an intermittent problem where, on CW transmit, neither the SWR
display nor the RF (power out) display will show any bars.  The actual
power out is normal so this is a display problem only.  I reloaded the
firmware and did a re-initialization with no help.

The K3 is almost ten years old (1737), so I'm suspecting a possible dirty
connector?  Or what?

Any ideas on what to check next appreciated!

Thanks, Lee

Lee,

Have you checked that K3 to see if it has the gold pins.  Remove the
Front Panel assembly to check.
If it has tin plated pins, often just removing the front panel and
putting it back will clean enough oxidation off the pins to correct the
problem, but if it has tin pins, get thee gold ones from Elecraft.
