[Elecraft] K1 2427 operational, but a quick question

[Bernie Gardner]

I finished K1 #2427 and actually made a contact to Austria with it Friday. 
Today I added the KAT1 antenna tuner which seems to work as well (after I 
remembered to move the jumper to get the power readings from the tuner...)  
Overall a very nice package, but I have one issue I would appreciate some 
advice on. During the voltage checks in the first part of the RF board 
assembly:  the voltage on pin 5 of U3 was 3.73, slightly less than the 
specified 3.8-4.2 range.  Other voltages were in the lower part of the 
specified ranges.  I checked with two different dvm's and got very similar 
results, though admittedly neither are high accuracy...  Everything else 
looked good, and I decided to continue on.   As I said, the radio worked 
perfectly when completed, but should I be worried about the low voltage.
