OK, went and got one for $60. Small, light. Fan is not quiet. Handles 25 amps OK.

Nasty noises about every 100 KHz down on 80 meters, continues up through 40 meters and peters out in strength. I suspect (as advised by others on this list) I can quiet it all down with some effort, but now I think we get what we pay for in this instance.

It is certainly usable, does not make "hash" all over any frequency range, but if you try to have a QSO on about 3810, you need signals well over S9 to get over the power supply noise. And the noise gradually moves in frequency.

That's my take on it.

anyone have any experience with this unit? Our local store has them on
sale for very little money and if there isn't much hash I might buy it for
a spare.
