[TenTec] Heil ProSet adapter with Orion -- hum?

Duane,
Hello my friend, well I can tell you what works here.
I have a Heil Goldline with the standard Heil TT cable, works fine EXCEPT on 
10 mtrs when I use 400 watts out, I get lots of RF feedback (all the lights in 
Orion flicker on/off). Also, I have a Heil BM10 headset, again with standard 
Heil cable adapter, works fine also. 

The RF feedback issue is one that has been discussed over & over. The 
recommendation is to have the wiring just like it shows in the Orion manual. 

ALSO... I heard that TT has since done MODS to have the Mic shield connected 
to chassis ground on the Orion.

Does anyone know (before I call PAul at TT) exactly how the mod is done on 
the Orion. I would like to do it exactly like TT does it.

Thanks,
Lee, KC9CDT
