[Elecraft] K1 KFL1-4 Band indent

[Don Wilhelm]

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,
