By "Frequency Agile", I mean something where you flick a thumbwheel to the 
required frequency, and press the "ON" button. You're there. *Not* something 
that requires changing coils (or taps on coils) and tweaking various variable 
caps... just like the modern Ham rigs: Just spin the VFO dial, and you're on a 
new frequency. (seconds, not hours.)

The idea being that you can just toss the unit into the back of the car and 
trundle it to a sister station as an instant backup. Dial up their freq, hook 
it up, and press the button. It would be even better in a multi-station setup, 
where moving the input , output, and changing the freq would be all that's 
required to get a failed station back on the air in mere minutes.
