[Elecraft] [K3] XV144 fault (offset problem?)

[Matt Zilmer]

Hi Doug,

The K144XV here had an +850 Hz offset when received.  There is about
25Hz of temperature drift as well.  Combined, the 875 Hz could be
canceled using the offset setting.

12.5 KHz seems excessive, and that's the highest I've heard of.

Note: My K144XV is one of the first ones produced (early 2010), and
has remained stable (as above) during the last year.

Hope this helps.  Doesn't sound like it will.

73 and HNY!
