[Elecraft] K2 VFO Freq Display Stuck (again)

[TI2/NA7U]

Yes, I remember that Enc B was fine last time, also, but it's definitely not
now.

One correction to my previous post, when the encoder is connected the
voltage on Enc B and Enc RD vary between .4-.46V, not from zero. 

With the encoder pins 3 and 4 disconnected and measuring directly at the
encoder pins I see the voltage hold about 4.4V on both 3 and 4. As I turn
the encoder the voltages on either pin drop to zero, but only
intermittently.

The voltage at U3 pin 14 is about .3V (even when the encoder pins are
connected it measures about .1V, whereas the voltage chart says it should be
3.1V and varying). 

Hope I did the measurements correctly.

73,

Casey
