I don't have a signal source outside the bands, but with an antenna analyzer 
connected to the output and a 2300 ohm resister from plate to ground, it will 
tune to 1.2:1 SWR on on the analyzer set to 3750. Is that the same test?

Hi Dick:

I suspect it is the pi-network inductance.  Had a problem recently with a home 
brew rig and finally figured out what the problem was.  If you have a wide band 
signal source, drive it with that, with the tuning controls mid scale, into a 
dummy load and see where the response frequency is.  Bet it is not near 80 
meters.

Even a signal generator will work.
