[Boatanchors] Diamond sx-100 SWR/Power Meter

[Al Parker]

Hi Tom,
	Do you have a schematic for it?  Or just look inside?  Perhaps there's 
an RF choke across the line, perhaps to bleed off static electricity. 
It would show nearly a short to ground to an ohmmeter, but very high 
resistance to RF.  If it's gotten toasted, maybe some shorted turns, it 
could be your SWR problem.
