Well, I see that David says it's quiet at RF-
"Its very small, quiet - both physical and appears to be on RF too"
I only see a 14A PS from Jetstream that's the same size- is that what
you tested?
And since W&S rebranded it, they may have changed other
characteristics, too.
It'd be interesting to see how the W&S unit did on a test bench, since
it does look attractive.
I've had reliability problems with the MFJ-4125, although the unit appears
to be robust now, after two trips to MFJ, and some rework by myself.
But I tend to work it hard, DXpedition and contest RTTY.
BTW, I have found that not all equipment is more expensive in the UK.
I have a TH-D7E that was cheaper in the UK (and had bandpass filters
for the 430-440 satellite band, instead of 440-450).
You just have to shop carefully.

I'd be interested in hearing if that unit has RFI problems. I had one
that looked identical to that, with the brand "Jetstream" on it, on a
spectrum analyzer a day or two ago. Appeared to produce lots of RF
hash. Might be OK across a battery, but looked really bad by itself
(hash at -80 dBm or so). The hash was riding the power cord as well as
the output terminals. Did not do a through check, not enough time, just
a quick look.
