1. [TenTec] One last chirp (score: 1): Author: jwodell@ameritech.net (Jerry W. O'Dell); Date: Thu, 07 Jan 1999 19:19:52 -0500; As an Omni 6+ user, I was curious about the problem, so I actually gathered some data -- can your imagine, data on a ham radio topic! Took my FT840, and listened to W1AW on 20 meters. Ye gods. Clicks; /archives//html/TenTec/1999-01/msg00121.html (8,450 bytes)
2. [TenTec] One last chirp (score: 1): Author: n4lq@iglou.com (Steve Ellington); Date: Thu, 7 Jan 1999 19:35:03 -0500; The poor signal from W1AW was most evident on my Omni V. With the IC-706, it was poor but not as obvious and with a TS-870 it is inbetween. I'm not sure why it sounded so bad on the Omni. Maybe Paul; /archives//html/TenTec/1999-01/msg00122.html (8,333 bytes)
3. [TenTec] One last chirp (score: 1): Author: geraldj@ames.net (Dr. Gerald N. Johnson, P.E.); Date: Thu, 07 Jan 1999 18:43:42 -0600; I listened to the beginning of 0000Z code practice. I still can't find anything but a hard leading edge. Its most pronounced with the signal nearly centered in the SSB filter, least pronounced with 5; /archives//html/TenTec/1999-01/msg00123.html (8,931 bytes)
4. [TenTec] One last chirp (score: 1): Author: paulc@mediaone.net (Paul Christensen); Date: Thu, 7 Jan 1999 20:20:27 -0500; Very True. There's a marked difference in received keying dynamics between radio with ladder or Cohn I.F. filters and crystal lattice I.F. filters. The lattice filters tend to even those waveforms w; /archives//html/TenTec/1999-01/msg00124.html (10,458 bytes)

TT's organization and engineering were originally by g; /archives//html/TenTec/1999-01/msg00129.html (10,937 bytes)
6. [TenTec] One last chirp (score: 1): Author: geraldj@ames.net (Dr. Gerald N. Johnson, P.E.); Date: Fri, 08 Jan 1999 01:39:25 -0600; The circuit of the filter has little to do with the time and amplitude response. It takes fewer crystals to get a square edged frequency response if the time response is neglected. If the time respon; /archives//html/TenTec/1999-01/msg00131.html (10,234 bytes)
7. [TenTec] One last chirp (score: 1): Author: andrenr@ul.com (RICHARD ANDREN); Date: Fri, 8 Jan 99 7:13:25 CST; This is confusing. A few weeks ago many of you told me how there was NO spike. Now I read that there is a spike "smack dab in the power area that drives many amplifiers". Maybe I'm the only one that; /archives//html/TenTec/1999-01/msg00133.html (11,238 bytes)
8. [TenTec] One last chirp (score: 1): Author: paulc@mediaone.net (Paul Christensen); Date: Fri, 8 Jan 1999 08:43:09 -0500; I don't disagree with you on this point Jerry. Only these transceivers (Omni V and Omni Six/Six Plus) have no front-panel adjustable DRIVE or ALC control that appear on other transceivers. My Triton; /archives//html/TenTec/1999-01/msg00135.html (10,139 bytes)
9. [TenTec] One last chirp (score: 1): Author: paulc@mediaone.net (Paul Christensen); Date: Fri, 8 Jan 1999 08:56:24 -0500; Rick, It's not easy to follow some of these message threads because there's so much information. In a nutshell, I am saying that: 1) The Omni Six/Six Plus does NOT have a leading edge power spike, bu; /archives//html/TenTec/1999-01/msg00136.html (13,635 bytes)
10. [TenTec] One last chirp (score: 1): Author: carl.s.hyde@lmco.com (Carl Hyde); Date: Fri, 08 Jan 1999 09:43:47 -0500; After hearing all these comments about the CW signal of the Omni VI I also listened in on the code practice session last night with my Scout and the good old Collins 75A-4 station and the S-line. I d; /archives//html/TenTec/1999-01/msg00138.html (9,503 bytes)
11. [TenTec] One Last Chirp (score: 1): Author: andrenr@ul.com (RICHARD ANDREN); Date: Fri, 8 Jan 99 8:56:20 CST; I've done the same with a Drake C-line changing through different filters and set to fast AGC. I don't think I could actually tell the difference between a hard leading edge or a spike by listening.; /archives//html/TenTec/1999-01/msg00139.html (8,739 bytes)
12. [TenTec] One last chirp (score: 1): Author: geraldj@ames.net (Dr. Gerald N. Johnson, P.E.); Date: Fri, 08 Jan 1999 11:25:17 -0600; The easiest configuration (least mathematical) response curve for a lattice filter is more or less square with notches adjacent to the band for a tchebychev type response prone to ringing.

13. [TenTec] One last chirp (score: 1): Author: paulc@mediaone.net (Paul Christensen); Date: Fri, 8 Jan 1999 15:27:22 -0500; There is, and this gets us right back to the Omni Six's CW transmit BFO placement with respect to the 2.4 kHz I.F. filter: the two modes sound different in CW because the FSK offset is well above th; /archives//html/TenTec/1999-01/msg00153.html (9,378 bytes)
14. [TenTec] One last chirp (score: 1): Author: geraldj@ames.net (Dr. Gerald N. Johnson, P.E.); Date: Fri, 08 Jan 1999 15:55:59 -0600; I don't think its the placement of the transmit BFO frequency in the filter, I think its overdriving the system and thus negating the keying shaping by the ALC. I propose that a better and simpler cu; /archives//html/TenTec/1999-01/msg00156.html (8,896 bytes)
15. [TenTec] One last chirp (score: 1): Author: paulc@mediaone.net (Paul Christensen); Date: Fri, 8 Jan 1999 17:25:08 -0500; I looked at this early-on in the investigation. The bottom line is that BFO frequency placement within the filter's passband is a dominant factor. Either by keying in the FSK mode or deliberately sh; /archives//html/TenTec/1999-01/msg00160.html (8,747 bytes)

Add a threshold to the RF side of the keying so it doesn't happen as soon. Maybe a couple diodes some where to require a little higher voltage to turn on the RF while causi; /archives//html/TenTec/1999-01/msg00164.html (8,041 bytes)
