[Elecraft] K3 Power Supply Question

  In response to many questions about what I chose, the answer is I 
bought two different supplies, with different intended uses.

One was the Gamma Research unit, nice and small, but low capacity (okay 
on SSB and CW, too low for digital modes unless you run 10 watts or so 
due to its power duty cycle limitations.  It does fit easily in the 
carry case side pocket of the case Rose Kopp makes.  It is fairly quiet 
RF wise, but I have heard stories of failures from some folks.

The other is the PowerWerks switching unit,  It has much more capacity, 
but is larger; it barely squeezes into the side pocket and once in, is a 
tight enough fit that I am worried that the carrying case could fail due 
to the stress imposed.  It is also fairly RF quiet.

I have decided to use the Gamma Research unit on portable light duty 
trips, and if anticipating Digital modes, bring the PowerWerks unit 
along.  Currently it powers the K3 in the shack.

Thanks a ll for your help and interest.
