121. [TenTec] RE: OMNI VI Connector 52 (score: 1): Author: paulc@mediaone.net (Paul Christensen); Date: Sat, 20 Mar 1999 07:14:02 -0500; Given the benefit of clickless T/R switching and the fact that most ops who have tried this mod since I introduced it last year prefer to control their side tone with the AF control, it should at lea; /archives//html/TenTec/1999-03/msg00228.html (13,347 bytes)
122. [TenTec] Re: Connector 52 & 2800 Hz Filter (score: 1): Author: paulc@mediaone.net (Paul Christensen); Date: Sun, 21 Mar 1999 06:50:33 -0500; Roy, In order to completely eliminate the "micro-chirp," you may need to modify the TX AUDIO BOARD (BFO Osc.). The INRAD filter helps to clean up the dirty-sounding CW note due to the CW TX BFO place; /archives//html/TenTec/1999-03/msg00242.html (8,374 bytes)
123. [TenTec] Inrad 2.8K (score: 1): Author: paulc@mediaone.net (Paul Christensen); Date: Wed, 10 Feb 1999 08:15:43 -0500; John, The INRAD 2.8 kHz filter was developed to help cure a dirty and sometimes chirp-prone CW note on the Omni Six series transceiver To this end, the filter achieves its goal.

[TenTec] Fw: Omni Six "Clicks" (score: 1): Author: paulc@mediaone.net (Paul Christensen); Date: Sun, 14 Feb 1999 11:11:15 -0500; Several weeks ago, someone on the list indicated that they could not rid their Omni Six of audible "clicks" while listening with headphones. I suggested removing plug 52 on the AF/IF Circuit board, b; /archives//html/TenTec/1999-02/msg00191.html (8,592 bytes)

The effect of the CW transmit BFO passing through the filter's steep knee not only exacerbates a slight chirp emanating from the Omni Six's BFO board, but there ar; /archives//html/TenTec/1999-01/msg00042.html (10,279 bytes)

[TenTec] Re: N4LQ and the 2.8kHz Pill (score: 1): Author: paulc@mediaone.net (Paul Christensen); Date: Mon, 4 Jan 1999 08:34:58 -0500; The W1AW 20-meter CW signal is a perfect example of what we sometimes hear from the Omni Six. Mine sounded identical to it prior to the mods. Quite honestly Steve, I don't believe the ARRL's waveform; /archives//html/TenTec/1999-01/msg00051.html (13,688 bytes)
128. [TenTec] Re: N4LQ and the 2.8kHz Pill (score: 1): Author: paulc@mediaone.net (Paul Christensen); Date: Mon, 4 Jan 1999 12:20:29 -0500; Yes, technically this works, but if the CW transmit offset is not fixed at the design frequency of 9,000.400 kHz, the frequency display will not track accurately. The Omni Six is capable of agile CW; /archives//html/TenTec/1999-01/msg00055.html (10,979 bytes)
129. [TenTec] Omni VI chirp comment (score: 1): Author: paulc@mediaone.net (Paul Christensen); Date: Tue, 5 Jan 1999 18:25:56 -0500; Hi Steve, Let's address this one issue at a time and I believe it will make sense. As I've been advocating, the 2.8 kHz filter may only be a partial solution, depending on just how badly the Omni chi; /archives//html/TenTec/1999-01/msg00074.html (15,213 bytes)
130. [TenTec] Omni VI chirp comment (score: 1): Author: paulc@mediaone.net (Paul Christensen); Date: Wed, 6 Jan 1999 08:58:22 -0500; Hi Steve, Well, I suppose I would consider using another buffered crystal oscillator ONLY for the CW offset. Then add a buffered stage to the existing circuit. Finally, use a damn-fast transistor to; /archives//html/TenTec/1999-01/msg00085.html (11,709 bytes)
131. [TenTec] Omni VI chirp comment (score: 1): Author: paulc@mediaone.net (Paul Christensen); Date: Wed, 6 Jan 1999 20:23:11 -0500; Yes, another good point guys. Prior to the mods, my Omni Six's CW note sounded much different when switching between sidebands on an external receiver, using a wide I.F. filter setting. The same is t; /archives//html/TenTec/1999-01/msg00101.html (12,232 bytes)

133. [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)
134. [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.

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)
136. [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)
137. [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)
