OMNI A/B/C/D AGC Mod
From the Ten-Tec Reflector May 29, 2000
I've been working for 2 days on the Omni C trying to modify the agc to reduce the popping effect of strong signals. The cw contest provided plenty of super strong signals to test with! Here's what I learned:text/html2023-11-04T00:08:25+0000n5na (n5na@undisclosed.example.com)565schemindex

Orion Schematic Index
From the Ten-Tec Reflector December 6, 2004
On the Ten-Tec website, there is a ZIP file containing the Orion schematics. There are 44 separate drawings, but no index. Below is an index I created by looking at the title blocks of each drawing. I hope this helps the rest of the reflector.text/html2023-11-03T23:07:25+0000n5na (n5na@undisclosed.example.com)566schemindex

Orion Frequency Calibration Procedure
From the Ten-Tec Reflector May 22, 2003
When I checked the frequency accuracy of my new Orion, the LCD readout when 10 MHz WWV was zero beat was about 20 Hz low (after a long warmup). On 15 MHz WWV it was 30 Hz low. That's not too shabby, but when the receiver displays down to 1 Hz you tend to want to make it more accurate.text/html2023-04-20T19:13:48+0000n5na (n5na@undisclosed.example.com)pt-11p - [Related Links]

https://tentecwiki.eqth.net/doku.php?id=565frontandrearaudio&rev=1632987626&do=diff
The orion has a front microphone connector as well a rear din connector which can be used as well.
Both connectors can be controlled with a menu setting. The front connector is designed to be used with a directly connected microphone and includes a microphone amplifier within the audio path. Through the menu one can set a hardware gain as well a software gain for the front connected microphone.text/html2021-07-31T14:36:34+0000pa1ap (pa1ap@undisclosed.example.com)playground:connecting_orion_565_alternative_display.pdf - created
