Am I reading something wrong? You say that you would need +/- 144 Hz,
and Wayne is saying that you can get +/- 10 Hz with the extended
temperature compensation. That seems that it would be good enough.
I'm also seeing all this complaining about stability, and the only
counter example appears to be +/- 1700 Hz at 1296Mhz for a TS2000, which
doesn't strike me as all that good either.
Is the real issue that there is no support for an external reference?

The specs for frequency stability are not good enough for the JT65 modes (+/- 1
ppm typical over 0-50 C). On 2m, that would be +/- 144Hz. The extended
temperature compensation improves that, but it will never be as stable as a K3
with an external reference.
Did you expect it to perform much, much better than the specs?
The FT-817 specs are: ± 4 ppm from 1 min. to 60 min. after power on. 25° C: 1
ppm/hour

The more I see, the more I realise that the promised 2M unit is going to be a
very poor option for people who use VHF and UHF seriously.
I have re awakened my use of HF, but I did buy the Elecraft KX3 with the
promise of a decent 2M option.
Where do I apply to return my KX3 for a full refund ?
