Correct - it was by the signal generator.

Yea - this was done at about 75F with a relatively cool transmitter.

I would agree - Like I would have not have purchased the repeater if the price 
was increased say $20 (guess; ~1.4%) to cover better cables?  

Actually - I wish they would have just modified their 1 RU commercial product 
or dstar.
