[Elecraft] K2 Frequency Alignment

[Bob Lewis (AA4PB)]

Here's another way to calibrate the 4MHz oscillator. Many frequency
counters have a reference oscillator output (usually 10MHz) available.
Put the K2 in freq counter mode. Apply the 10MHz reference oscillator
to the K2 counter input. Adjust the 4Mhz K2 oscillator until the K2
LCD reads 10MHz (or whatever your ref osc freq is). This should get
the K2 to whatever accuracy the reference is +/- one count.
