[TenTec] RF Getting back into Rig Problem

[Dave Tipton]

Thanks to all for your suggestions.  It seems that this is a fairly common issue.  Here are the things I've gleaned.
   
  1)  Antenna, albeit resonant, being so close to the shack (20 feet overhead) may be apt to coupling to ground in the rain.
  2)  Toroids, Toroids, Toroids.  At least 1 for each input to the rig, including on the power leads.
  3) I need to install an earth ground, and potentially share it with my satellite TV's ground.
  4)  TenTec needs to seriously look at this issue, because it sounds like it's a VERY common one and maybe indicative of a design flaw.
   
  In regards to number 4, I still love this rig.  I will not be giving it up any time soon.  Just need to make some mods to the way things are set up.

  I had a problem with my O1 & O2 with the TT 706 mic. Key stuck and RF in the 
audio. I found that when I pointed the beam right over the shack the 
problems started. I was able to eliminate almost all the problems by taking 
the 706 mic apart and using kitchen foil placing it around the little PC 
board pre amp and leaving a tab to put under one of the bottoming mounting 
screws, that grounded the foil. I first put black tape on the board to 
insulate it from the foil. Yes, the shack is grounded to a common 2, 8 foot 
ground rods 5 feet apart.
I also found last year when I had the key stuck problem it turned out to be 
the PTT button switch. It was bad. Had to bang on it to get back to receive.
My 2 cents.
