[TenTec] Orion and MIKEs

[N0KHQ at aol.com]

Well, thank you Bill.

If owners of Jupiter's and Orion's would get their ohm meters out and check 
their rigs as suggested in an earlier email they will find, on the Jupiter 
approx. 4 ohms of resistance from pin# 2 on the mic plug to the ground lug on the 
rear of the rig and on the Orion you will find approx. 6 ohms of resistance.

Anything that's not absolutely at ground potential will look like a conductor 
to RF.....and that's a fact.

If your not experiencing any issues with RFI or more than desirable receiver 
noise......then don't worry about it.

But for those folks that are having problems.......you need to take a look at 
your stuff.

And contrary to the suggestion that your antenna should be 100' away from 
your shack is not true. You can put your antenna on top of your house and put out 
legal limt without any indication of RFI if your station system is properly 
grounded.

A good place to start is at your electrical service entrance, the place where 
the main panel ground is attached to a grounding rod.......when was the last 
time anyone went out, disconnected the large ground wire......sanded the 
grounding rod and cleaned the ground wire......then reattach it and made water 
tight. Oh yeah, be careful, it has been my experience that some thoughtless home 
owner or less than a journeyman electrician may have crossed the black wire and 
white wire during new or old construction of the electrical system. When you 
take the ground wire off make sure you don't use you hand, use a pair of 
lineman's or something.....get you volt meter and measure from the ground wire to 
the grounding rod for any trace of voltage......if its clean....no 
problem......if its not clean.....you got a problem and you'll have to got through the 
entire electrical system until you find that one little wiring error. It happens. 

Just my $ 0.02
