Hi Ken - I saw that sheet, too.
I understand what you're saying about the firmware being to enhance the accuracy to the .5 ppm, and I'm sure you're correct about that. My statement about Elecraft wasn't my "feeling"; it was a reporting of fact. My "feeling" is that they're not being as honest as they should, but that's just me; others have higher tolerance for such behavior. As I type this, I see that Eric chimed in, with an update on the firmware status for this - thank you, Eric. I ordered a 2nd K3 last week (pre price increase - yippee!), but without the 1ppm TCXO. I'll be interested to see if I even notice the difference. For now, I'll be enjoying my K3. Thanks/73!
