1. [TenTec] Orion Processing (score: 1): Author: "Bernard(wtrone)" <wtrone@comcast.net>; Date: Wed, 16 Mar 2005 22:26:46 -0600; I don't know if I have seen the numbers (operating speed, etc.) for the Orion's processor and DSP chips/ units. Does anyone have them? Since this design is probably going on 3 years old, what capabil; /archives//html/TenTec/2005-03/msg00388.html (7,209 bytes)

Re: [TenTec] Orion Processing (score: 1): Author: "Bob Cunnings" <cunnings@lectrosonics.com>; Date: Thu, 17 Mar 2005 15:49:58 -0700; As for the Sharc DSP parts, they appear to be misidentified on the schematic. I believe they are AD21065L, really, right? I've never heard of an AD21D56L. If so, the 21065 ran at a maximum of 66 MHz,; /archives//html/TenTec/2005-03/msg00397.html (9,577 bytes)

You could increase the 3rd IF passband or provide more exotic filtering. I'm not sure it would make a big difference for most people.
