[TenTec] Orion Mic Woes - Sounds like RFI but Wasn't

[Mike Brown]

I don't have an Orion Mark, but I've read about Heil mics and headsets 
working well with the Orion. I'm sure you should be able to have the same 
success. The Orion is used as contest rig, and I would think Ten Tec would 
make it compatible with the Heil headset, since I would say the Heil Headset 
is the most popular headset in contesting. Not the only one, but I would bet 
the most popular.
