1. [TenTec] Ten-tec noise and RX questions (score: 1): Author: W8JI@contesting.com (Tom Rauch); Date: Wed, 27 Oct 1999 00:17:04 -0400; Hi All, 1.) How clean is the transmitter of the Omni? Is it exceptionally clean, or about the same as most "modern" rigs? -x dBc at x kHz will work if anyone can help. 2.) How good is the receiver fo; /archives//html/TenTec/1999-10/msg00688.html (8,879 bytes)
2. [TenTec] Ten-tec noise and RX questions (score: 1): Author: geraldj@ames.net (Dr. Gerald N. Johnson, P.E.); Date: Wed, 27 Oct 1999 09:01:16 -0500; 1. The phase noise is better than most rigs. Check the QST review. 2. I know the Corsair II works well with really strong signals just outside the pass band. The Omni VI uses the same filters but dif; /archives//html/TenTec/1999-10/msg00694.html (8,452 bytes)

I have put an INRAD 400 Hz (lattice design) and NS (Ten Tec) 500 Hz (ladder design) filter in my rig's 9 MHz first IF to see if I could detect a difference in; /archives//html/TenTec/1999-10/msg00695.html (9,104 bytes)

Bear with me a moment... In using my NIR-12 I can select center fre; /archives//html/TenTec/1999-10/msg00700.html (10,842 bytes)
5. [TenTec] Ten-tec noise and RX questions (score: 1): Author: csturner@falcon.csc.calpoly.edu (Clark Savage Turner); Date: Wed, 27 Oct 1999 11:14:39 -0700 (PDT); Good point. I believe that the narrowband noise does make it harder under some circumstances to pick out a weak signal. For the moderately strong signal in QRM, or the weak signal in QRM, the filter; /archives//html/TenTec/1999-10/msg00703.html (8,360 bytes)
6. [TenTec] Ten-tec noise and RX questions (score: 1): Author: geraldj@ames.net (Dr. Gerald N. Johnson, P.E.); Date: Wed, 27 Oct 1999 12:41:34 -0500; Some of the ringing is truly psychoacoustic. The harder the edges of the filter (especially the Kenwood 270 Hz filter used in the TS-430) the more the noise coming from the filter has a pitch. and th; /archives//html/TenTec/1999-10/msg00705.html (10,346 bytes)
7. [TenTec] Ten-tec noise and RX questions (score: 1): Author: W8JI@contesting.com (Tom Rauch); Date: Thu, 28 Oct 1999 09:57:59 -0400; Depends on the noise. With white noise, selectivity helps. With rough noises, it can hurt because the filter ringing will draw out the pulses and increase noise pulse duration. For example, on a qui; /archives//html/TenTec/1999-10/msg00728.html (8,465 bytes)
