[TowerTalk] Dummy load for 4-Square

[Mike Smith VE9AA]

Steve, 

I don't know why I never thought of that.  Very clever.

 Thanks for the idea !

Hi Mike,

Since you're only using it on ONE band, whatever inductance there is in the
total R, you could compensate for with some C.
You just can't use them across a wide span of frequencies such as 3 to
30 megs, because the inductance would totally 'kill it' on some freqs.  
I suspect the higher in freq, the worse the affect.
