Hi all, hope someone can offer some advice on this.
I'm building K2 #5551 and was concerned that most of the RF board capacitors
listed as NPO appeared to be ordinary blue resin-dipped ones.
I mailed Elecraft tech support a few days ago to enquire if the caps
supplied were NPO (zero tempera

I operated my K2 odd the back patio (blessedly screened) here in central
NC. Operation was hampered by some very threatening weather, requiring some
quick antenna disconnects when the thunder started rumbling nearby.
I guess I operated about 10 or 12 hrs in class 1B Battery single op CW only.

Windows uses just as much jargon as Linux does. You just don't notice it
because you have learnt it and become accustomed to it.

I could be wrong...but I think the NB is desgned to block out automobile
ignition noise, which comes in real handy when it is in a K2 doing Mobile
Operations.
You can try it in your car, with the car running and see what kind of
difference it makes.

I find the slow rate to be a bit too slow. The medium (5 KHz) speed
rate is about right but the step size is too big yielding audible pitch
steps. The fast rate for me is too fast. I'd be quite happy with the

Hi Gang...one of my wants for my K2 (and there's not much) is a
different tuning rate. I use the 10/50/1000 Hz setting which is 1 KHz,

Do not do a reset - you will have to re-enter all the settings for
filters/BFOs, and any other parameters you have so carefully set into your
