Hi Ken,
I service all of Elecraft's Classic Line of Products through my company

same thing for them. I can assure you that discontinuing the KPA100 was
no arbitrary decision. As with most 20 year and older designs, part

Thank you for your explanation Wayne. You are correct; turning off the
noise blanker eliminates wide-band key clicks from strong, wide signals.

I set about to find the NB level at which the clicks became noticeable. To

Hello again all,
Can the KPXA-100 be fully integrated with the K2? Full QSK and so on? Appears
to be mostly for the KX3 and KX2.
My 2003 K2 has all the options.
I can't believe Elecraft discontinued the 100w amp for the K2. What do have
then?
A full featured, basically, QRP radio! These little

any suggestion on tuner?

I have installed the production release R28.
My K4 (serial # 0223) has a built-in KAT4.
In early September 2021 I reported an issue with the
SWR bargraph display of my K4 to Elecraft support.
In some modes the SWR always shows 1:1 although
the real SWR is 1:2 or higher.
