K1 KFL1-4 Band indent

[Millerhill]

I have a 4 band board for a K1 that I want to sell, but not sure what bands are on it. How can I identify which board this is? I'm pretty sure it's 40, 30, 20, 15

Hi Steve,  The quickest for me is to count the turns in the toroids, cross check that info with the Xtal freq on the board.

Have a great day,

Steve,

You will have to check the crystal frequencies on the 4 band board.
Hopefully the builder mounted them so all the crystal markings can be seen.

Look at X1 - if it is 29.000 MHz, it has 15 meters, but if the crystal
is 26.050, it is built for 17 meters in place of 15.

Also the 30 meter crystal X3 should be checked to complete the story.  
If it is 18.000 MHz, the board was built to work in a K1 with a 150 kHz
tuning range.  If it is 18.100 MHz, it was built to work in a K1 with an
80 kHz tuning range.

If the buyer wants to change the top frequency band or the tuning range,
crystals can be purchased from Elecraft - all that is necessary is to
change the crystal(s) and re-align the bandpass filters.

73,
