[TenTec] Orion/Orion II Firmware

[Merle Bone]

Sinisa,
Your testing, and finding the "spur problem" in the V2 firmware, is a good reminder that most of us don't really validate the performance of the radio with our "limited usage." We may realize that the Notch Filter and the Auto-Notch filters are not removing the signal inside the AGC loop - thus leaving the radio subject to having the AGC pumped by a notched signal. And, we may realize that the "popping or sizzling" noise in the audio represents an error in the firmware. But most of us do not do enough testing to really know whether the Orion "performance" is up to where the original DSP code had it when it was tested - and praised - by the ARRL lab (Likely their testing would have found this "spur" problem). 

Thanks for taking another step in testing the radio. It would seem that TenTec did not find this bug in their testing. I think we all need to continue to test and validate Orion stability, function and performance.
