Dan,
I have seen this before, but it's been a long time and can't recall the
particulars.
Either your SWR meter is lying to you (calibration or someting broke) or
there is problem that is taking a different route -- e.g. RF floating around
that is either affecting SWR/power meter readings or getting into the radio.
Remember that with a Bird wattmeter, the actual power to the antenna is the
indicated forward power minus the indicated reflected power.
Try to isolate the problem's location -- How do things work into a dummy
load? And with the dummy load at the antenna end of the coax? (bad cable or
connector = other possible culprits).
