Elecraft KAT2 tuner for the K2


This was a three night project for me.



Night 1:


Install the capacitors, resistors, relays, BNCs, and ICs on the tuner control board.
Probably about 45 minutes of sorting parts into my little parts boxes/bins. Probably
another hour of actual work on the board.

Night 2:


About 30 minutes of bench time winding T1 for the control board then off to dinner.



Afternoon/Night 3:


Some serious bench time installing the relays, capacitors, toroids, header/pins, and
the wiring harness to the second board.  Once all of this was completed I then
had to remove the heatsink the K2 and add the RF connection to the main board in the
K2. After that you mount the KAT2 into the lid of the radio.

All in all there is probably about 6-7 hours into this project. The tuner is awesome.
I am really impressed at how well it works. It is incredibly fast and has a pretty
wide match range.
