At <http://www.radiodan.com/rfapps/vfd.htm> it is stated that the 5-kW
version of the VFD is new.

I'm sorry to hear this. All I can say is that I also have two Bird
wattmeters and an assortment of slugs; and the first thing I'll do when I
get a VFD is to check it against the Birds. If it's inaccurate I'll send
it back and hope they'll make it right. In any case, I'll report my
findings to the AMPS reflector!
Thanks for the heads-up.
