[Elecraft] K3 dumb Q about PPM, less dumb one about NB

[lstavenhagen]

Hi Guy,

Yeah I bought the TCXO3 option with my kit. I've just been tracking the
drift over the last day or so just out of curiosity to see how stable it is
which is why I asked. I left my window open last night and my room cooled
about 10 to 15 degs overnight. Sure enough, the osc. seemed to go low about
5hz. After 1/2 hour it had drifted back up about 2 or 3 hz.

Indeed astounding stability, tho how useful it actually is I don't really
know. I don't think even the digital modes care about variations that small.
My K2 probably drifts about 20 to 30hz from start to warmup and even then it
settles down in 15-20 mins. After that it's a rock compared to what I'm used
to from the old days (where you get that kind of drift during the CQ DX
alone hi hi).

I haven't entered my temp correction data since it's not enabled in the FW
yet. I'm keeping my sheet tho of course. It'd be neat to see how much more
stable it'll be once that is implemented. 

73,
