I've been using a SEC-1235 with my K3 for over a year now. Works great with
no switching noise. I did modifiy the power supply by adding a PowerPole
output connector pair on the rear. I also made a simple mod to the SEC-1235
fan circuitry so the fan runs slowly all the time, but can still go
It would be useful for those who use switching power supplies to
mention on what band(s) they've noted no switching noise with their
particular choice.

I have been using the Alinco DM-330MV.
Have worked all bands (just got a 12 m QSO today) that the K3 covers.
No switching noise noted.
Most operation has been 80, 40, 30 and 20 m.
Enjoy having the meter and ability to vary the output voltage.

OK - I've not heard any switching power supply noise from the SEC-1235 on
any band from 160-6 meters.
