[evlatests] Modcomp-free: L-Band

[Robert Hayward]

Sounds like the EVLA will need a new version of QUACK, and probably a 
new name...

If a gathering of ducks is known as a "flush", and a gathering of geese 
is known as a "gaggle", then a gathering of both waterfowl must surely 
be a "flaggle".

Thus the combined sound they make must either be a HACK or a QUONK. Take 
your pick...

Thank God it's Friday,
