[Elecraft] [K3] max input voltage on Ant 1 or 2

[David Ferrington, M0XDF]

Thanks all for replies - it appears the oven control is generating  
some harmonics that are getting onto the 5MHz and then I'm picking  
them up - if i don't create some form of closer connection - currently  
just have the output lead (floating BNC) about 1' from K3.
The single wire solution looks promising.
