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

[Paul Christensen]

Hmmm....I had thought IP (e.g. IP2 - IP3) refered to "Intercept Point" as an intermod measuring basis for receive performance, not
the transmitter...or is my assumption incorrect?  If so, then how is third and fifth-order transmit intermodulation generally
abbreviated?
