[TenTec] No 6M on the Orion (WTB: Ten-Tec 526 6N2)

[WA3FIY]

I suspect George is referring to the third and fifth order IM 
products of the final amplifier of the Orion, not the IP3 and IP 
5 intercept points of receiver.

As far as what the IM products will be in the case of load 
mismatch, I see no reason they would be much different than 
other 100 watt 12 volt final amplifiers.  Interesting question 
though.
