Hey Chad,

I am not familiar with the innards of the Array Solutions Un-un, so I 
suppose its possible that it is the same design as the Byte Mark W2FMI 
Un-un. Seems like a product comparison of various Un-uns with some QRO 
testing to see how they each handle power and mismatch would make a good 
NCJ or QST article.
