[Elecraft] Switching power-supply & K2

Sun Jul 13 12:58:06 2003

If the supply is still under warranty I would just send it back.
Clearly it should not be giving such a dirty signal.  I suppose you
could try some heavy capacitors on the output but if it is that bad, I
suspect it is giving RF hash and all sorts of other, undesirable things.
Frankly, I would just go with something else.

Subject: [Elecraft] Switching power-supply & K2

Hello elecrafters,
 I think i can answer the question myself.
 Today, I looked at the voltage of the power supply
 with an oscilloscope.

 It does *not* look like DC, it looks like the teeth of a saw.

I believe that this is the reason why the K2 refuses to work.

I=AEm not quite sure if I can charge the battery with that supply. Any
ideas?

I=AEm quite sure that i *can not* run the K2 with that supply.

Now thinking about a way to "tame the waves". Or should I say: pull
out the teeth? Any suggestions? Any dentists around?

 Martin
