   Hello from Texas A&M University in College Station, Texas.
   I keep reading about folks having problems with rf getting into their 
Orion, and thought I would send you my experience, to do with as you see 
fit. I read the Ten Tec archives, but cannot post.

   This is simply a FWIW regarding the issue of  RF causing problems with 
Orions. The window line I use is attached directly to one of two tuners 
sitting next to the Orion. One is an Ameritron ATR-30, and the other is a 
Palstar BT-1500. The window line is no more than two feet away from the 
Orion, at power levels from 10 to 1000 watts. The amp is an Ameritron 
AL-1200, the window line is ~45 feet of 300 ohm Wireman, delta matched to a 
75 meter dipole. The delta match radiates, and is directly over the station 
at about 35 feet. I have never had any problems with RF in over a year of 
daily operation.
