[Elecraft] New Power Supply

[Zoli Pitman HA1AG]

Hi Ruben,

I use samlex 1223's for many years, mainly on my expeditions and also 
with K3. You have to know that there are PS's made in BY which look 
exactly like the original 1223 but they have no output filtering and 
they have a different 12V connector.  They do have a noise issue, 
particularly on 80m SSB band. I know that these were sold at the 
Friedrichshafen hamfest a few years ago.

There is enough room behind the 12V connector to add some filtering 
inside. Noise issues can be fully cleared up. I can send U some photos, 
let me know if you need.

Don't worry, 1223 noise issues can be fully cleared up.

73!

It is also wise to add a varistor to protect your radio if the PS bites 
the dust.
