[Elecraft] K3 Rotary encoder

[evert at pa2kw.com]

Hi Gary,

Thanks for the info!

Removing the LED board is not funny so I didn't.

How I did it :
   - remove the 2 encoders speed/mic and cmp/pwr (N5NA tells you how to)
   - remove the 4 screws (2 on top of the LED board and 2 on the back side of the front panel PCB) and pulled the 2  4.8 mm studs away underneath the LED board
   - gently push the LED board towards the front panel PCB. (This gives a lot more space to clip the pins and remove of the two remaining encoders).
   - clean up all the holes
   - slide the LED PCB and the 2 studs back into its original position (BEFORE soldering the new encoders !!)
   - put the encoders in place one by one with abt 1.4 mm distance to the front PCB (nylon washer, I used a piece of ty-rap) and solder them.

Thanks all for the on-list and off list help and suggestions.

73, Evert PA2KW

N5NA has written an excellent account of replacing the small push-button encoders.

https://www.n5na.net/s9y/index.php?/archives/26-Replacing-Elecraft-K3-Push-Button-Encoders.html

I have replaced all of these encoders in several K3 radios over the past
5 years.  It is not a job for the faint-hearted. However, if you take your time and cut the mounting pins of the encoders before you unsolder them, then you will succeed.  Do not attempt to remove the LED board. Make sure you wick out the mounting holes thoroughly or you will have difficulty installing the new encoders.

Good luck
