[Elecraft] KTCXO3-1

[Duncan Carter]

Although I haven't changed the TCXO settings, after a very short warmup 
period, my K3 stays within 1.5 Hz or less, mostly within about 1/2 Hz 
with the main source of errors being what I assume are integer rounding 
errors in the frequency generation chain which shouldn't be affected by 
the auto temperature correction.; I have difficulty seeing this as a 
real issue but maybe I'm just lucky.  I have memory settings so that I 
can quickly check 2.5, 5. 10, 15, and 20 MHz frequency standards and I'm 
close enough to WWV to not receive it by sky wave so multipath errors 
aren't a factor.

My apologies if this offends you but as far as I'm concerned, this is 
another topic in the "Much Ado About Nothing" category.
