I use a SEC 1223 with my K2/100 and TS430S.

The SEC 1223 does generate some RF noise. This is most noticeable on 160m. It can be tamed with a little work. If you go to my review on eHam.net, you can see how I fixed the issue.

I've been using it for a couple of years now. For most use, it stays quiet. If you are running RTTY or CW with lots of CQs, you can get the fan to come on, and it is loud. It doesn't come on often enough for me to bother trying to fix it.
