All,
While Bill's comments are useful, I can say that the TF3MA sidetone mod
is designed for the Rev A K2s (below SN 3000). Those K2s SN 3000 and
above have improvements in the sidetone waveform shaping. If you have
upgraded your K2 below SN 3000 with the A to B kit, then you have the

JMHO but I have a contrarian opinion on the KAF2. I installed one but
resold it after several months of use. I do a lot of weak signal work on
160 and have probably tried about every audio filter known to man. The
When you listen to the K2's receiver it's like there's nothing between the
antenna and your headphones but signal.

If I could throw in a few thoughts:
Building my K2 was by far the most fun building experience in my 45 years
of hamming, including many Heathkits.
The KAF2 filter is superb imho. My K2 has a KDSP2 instead, but I use an
external KAF2 on my old Heathkits, and it turns their wide receivers from

Once you have an idea what you're aiming
John,
If you want only CW, the basic K2 and KPA100 will do that for you.
If you need a tuner, the KAT100 is a good wide range autotuner.
The basic K2 covers 80 thru 10 meters except for 60 meters.
To add 60 meters, the K60XV kit is in order and to add 160 meters and

Just to copy you in to an enquiry sent to Waters and Stanton in the UK
I intend to buy the K2/100 kit but need to be sure about precisely what I

Any advice welcome - and needed1
