[Elecraft] High Accuracy TCXO

Wed Mar 5 04:11:58 EST 2008

Sorry to continue this thread (1 and only post on this), but ....

I don't remember it being described as 0.5ppm - only as 1ppm - it's on the
order page as +/- 1ppm.

OK, so there may have been a mail saying with firmware Elecraft might be
able to better that (I can't be bothered to search the archives to find out
frankly).

But its sold as a 1ppm TCXO. I don't believe it is advertised as anything
other than a 1ppm. The only ref. I can find on the K3 products page is:
"- All signal sources phase-locked to common 49.380 MHz reference
oscillator; 1 PPM TCXO option"

As one who has railed against the previous delivery delays and is still
waiting for the KRX3 and KDVR3 (lets not go there, I know and accept why the
delays), I think I must defend them on this one - they are not advertising
something here that you are not getting.
