[Elecraft] K2 - Variable Power Out

[Don Wilhelm]

Fred,

I certainly can't help with your internet access - but perhaps I can 
help with your K2/100 problem.
Go to the Elecraft website and find the K2 Optional Power Control Mod - 
or use the direct link http://www.elecraft.com/Apps/Power_Control_Mod.html.

If that does not help, you may have a problem with the KPA100 wattmeter 
section.

73,
