I'm kinda lost here, I thought this thread started with the K3 clock losing
time - what's RTC? - Is it Real Time Clock, in which case, that's what it
is. If you meant Radio Time Control, that it is not afaik.
So I don't believe this rig is picking up time signals from anywhere?
Someone put me right here if I've got this wrong?
My K3 clock, which I set about 18 hrs ago and the rig has been off for about
the last 12 of those, has lost about 4 seconds.
Now I don't think that's particularly good, even if its based on simple
electronics with no kind of sync with network etc.
I presume Eric or Wayne will see this post sometime and so they will be
aware, but I'm not about to worry them or me about it right now, they have
enough on their plates.
