[Elecraft] [K3] K3 on 500 kHz

[pd0psb]

Hello Dick,

I was immediately thinking of you when 500kc permission in NL got through,
it must feel very special to key-down on your old band :-)

A good option for 500kc is the Juma kit:

With a few mods (extra i/o's) it might be an elegant solution with the K3.

Happy 2010!
