[TenTec] trouble with tt centurion

[John]

Hello  I thank all for the loads of suggestions I got to improve the stray rf in the shack .  by using two of the suggestions I have eliminated most of the rf feedback on 40 and about 50 percent on 80 meters.  I made a choke balun and placed it after the amp , removed the outboard tuning pod away from the amp to about 4 feet on the side of the desk , placed two rf chokes on the mic cord and I had two grounding braids that were hanging from the grounding bus that were not being used  and just hanging off the bus so I removed the two grounding braids .  I intend to have 4 jumpers made from cable experts and replace the jumpers I made. ( I suspect a intermittent short )  and get a couple more line chokes and place them on other wires connecting the amp , radio , power supply etc.  again thanks to all .  I hope all had a very happy thanksgiving.  John kb2huk
