Thanks Bob & Mike for the replies.
Mike the antenna is a 3 element SteppIR and all antennas, 20 to 6 metres,
are at the same location.
Bob my first test was to search for a bad hunk of coax. All seemed okay so
then I tried bypassing the various components. The use of a dummy load
still gives me a discrepancy in SWR but less dramatic.
I've also tried another test. In this case I fed the Hercules to full
power. At 500+ watts BOTH wattmeters agree (or a close enough to not be a
I think that there's a little "something" is going on between the Orion
output and the Herc output. When I've had a bit more coffee I'll try a
significantly longer piece of coax from the Orion to the Herc and see if
that helps. If I have success I'll get back to the reflector.
Again, thanks to all who commented.
