[TenTec] OK , sounds good

I have just a few more comments on this.  First, I have several users 
running the Orion with the 9 mhz IF mod, LP-Pan, and TRX-Pan.  This 
works quite well and is very stable.

Second, I also have an interface with SDR-IQ.  In this setup, no 9 mhz 
IF output mod is needed at all on the Orion.  Instead, one wire is added 
inside the orion that goes between the sub-reciever antenna input and 
the spare jack on the Orion.  This allows SDR-IQ or the Flex 1500 to 
share the same antenna with the Orion.  My software keeps the two radios 
in lock step, also providing a great panadapter function without the 
need for a sound card or 9 mhz IF mode.
