1. [TenTec] Pegasus S-Meter Anomaly (score: 1): Author: mark@microenh.com (Mark Erbaugh); Date: Wed Jan 29 15:59:49 2003; Jerry It would be nice to know the algorithms used by AGC in the Pegasus. Good suggestion. The Pegasus interface software interface allows you to query both the analog and digital signal levels. I mi; /archives//html/TenTec/2003-01/msg00655.html (8,891 bytes)
2. [TenTec] Pegasus S-Meter Anomaly (score: 1): Author: w5yr@att.net (George, W5YR); Date: Wed Jan 29 15:20:27 2003; Jerry, the Kachina 505DSP used a similar combination AGC arrangement and provided a separate control for adjusting the degree of AGC control in the front end, etc. 73/72, George Amateur Radio W5YR -; /archives//html/TenTec/2003-01/msg00653.html (9,255 bytes)
3. [TenTec] Pegasus S-Meter Anomaly (score: 1): Author: geraldj@isunet.net (Dr. Gerald N. Johnson, electrical engineer); Date: Wed Jan 29 11:54:06 2003; It would be logical to me for the RF AGC to be fast while the audio AGC was slow and for the RF AGC to be faster on strong signals to protect the A/D better. The DSP always works better with the stro; /archives//html/TenTec/2003-01/msg00645.html (8,445 bytes)
4. [TenTec] Pegasus S-Meter Anomaly (score: 1): Author: n9dg@yahoo.com (Duane Grotophorst); Date: Wed Jan 29 10:15:40 2003; One other thing to think about is if the IF gain pot has been "tweaked" for more gain you will see degradation of the strong signal handling capability of the Pegasus (the Jupiter too I would assume); /archives//html/TenTec/2003-01/msg00641.html (11,071 bytes)
5. [TenTec] Pegasus S-Meter Anomaly (score: 1): Author: mark@microenh.com (Mark Erbaugh); Date: Wed Jan 29 09:57:57 2003; Jerry, Thanks for the reply. I suspect it is a combination of the two and the fact that the Pegasus has a 15 kHz roofing filter so it was up to the DSP to get rid of the signal anyways. If the AGC we; /archives//html/TenTec/2003-01/msg00639.html (8,228 bytes)
6. [TenTec] Pegasus S-Meter Anomaly (score: 1): Author: geraldj@isunet.net (Dr. Gerald N. Johnson, electrical engineer); Date: Wed Jan 29 01:07:56 2003; The splatter could have been from an overdriven Collins rig, or an overdriven A/D. The envelope of the SSB signal also follows the syllabic variations of the audio signal, so a fast AVC would show sy; /archives//html/TenTec/2003-01/msg00630.html (7,731 bytes)
7. [TenTec] Pegasus S-Meter Anomaly (score: 1): Author: mark@microenh.com (Mark Erbaugh); Date: Tue Jan 28 23:28:21 2003; Jerry, Thanks for the reply. In previous correspondence with Gary Barbour at TenTec, he did tell me that the SMeter reading is actually a combination of both the analog RF and digital signal levels.; /archives//html/TenTec/2003-01/msg00628.html (9,410 bytes)
8. [TenTec] Pegasus S-Meter Anomaly (score: 1): Author: geraldj@isunet.net (Dr. Gerald N. Johnson, electrical engineer); Date: Tue Jan 28 22:38:20 2003; It may be that there are two AVC loops. I'd expect one working at RF to protect the A/D from being overdriven, and a second one working after detection and filtering to level the audio for the speake; /archives//html/TenTec/2003-01/msg00626.html (7,947 bytes)
9. [TenTec] Pegasus S-Meter Anomaly (score: 1): Author: mark@microenh.com (Mark Erbaugh); Date: Mon Jan 27 23:18:59 2003; I've been messing around at developing my own Pegasus control software and I've encountered an anomaly with the SMeter. It may be related to the design of my software, but I think something real is g; /archives//html/TenTec/2003-01/msg00600.html (7,983 bytes)
