[TenTec] ORION BCI

[n4lq]

Ok but I doubt all of this. The Orion I had here was totally devistated 
by BCI from WHAS, 50kw about 10 miles away when using my loop. The loop 
gives any rig a hard way to go unless there's a tuner inline. A few rigs 
are able to withstand this such as my TS-480, TS-930, IC-756PROII and 
OMNI VI but the older TT rigs were totally rendered useless unless I had 
a tuner or my ICE filter in-line. Oh yes, the Jupiter and Pegasus were 
also wiped out. The Orion was blasted on 160 and 80m. My HQ-150 and SX-
122 don't notice a thing! '
