[Elecraft] K2 Receive tuning "blips"

[Don Wilhelm]

Jim,

Those are the 5 kHz transitions from the PLL.

First check the resistance across RFC15 on the bottom of the RF Board - it
should be quite low.  If it is open and you do not have an immediate
replacement, place a shorting jumper across it.

If RFC15 is OK and you still have the clicks, re-run CAL PLL.  Be certain
the bottom cover is in place when running CAL PLL.

73,
Don W3FPR
