[Elecraft] AC supply for KX-1

[Bob Nielsen]

I have not experienced any noise issues with mine, but possibly there  
are variations between units (not an unknown occurrence with MFJ  
equipment).  I have mainly used it on 20 meters and up so don't know  
how it might do on 160 or 80 (noise issues are often worse on the  
lower bands).

Milestone Technologies (N1FN) sells the CUP36, a similar supply which  
is popular among QRP operators <http://www.mtechnologies.com/cup/>.   
The web site indicates their tests showed it to be pretty clean, but  
the only review on eham.net mentions noise problems with that supply.

I searched a bit before buying my MFJ-4102 in 2004, hoping to find  
one that put out a little higher voltage so I could use it only to  
charge the internal battery in my K2 (which would avoid hash issues),  
but was unable to find a suitable supply at that time.
