1. [TenTec] Omni VI chirp comment (score: 1): Author: n4lq@iglou.com (Steve Ellington); Date: Tue, 5 Jan 1999 16:44:38 -0500 (EST); Although Paul's contributions concerning the 2.8khz crystal have been helpful, let me issue a concern of mine. The chirp seems to originate in the BFO of the tx-audio board. I spent nearly 3 months v; /archives//html/TenTec/1999-01/msg00071.html (9,838 bytes)
2. [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)
3. [TenTec] Omni VI chirp comment (score: 1): Author: n4lq@iglou.com (Steve Ellington); Date: Tue, 5 Jan 1999 20:51:38 -0500; In the old days of vacuum tubes, we learned the importance of isolating the crystal oscillator with buffer stages and keying a later mixer stage. The crystal osc. ran constantly resulting in a clean; /archives//html/TenTec/1999-01/msg00078.html (8,453 bytes)

[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)
5. [TenTec] Omni VI chirp comment (score: 1): Author: geraldj@ames.net (Dr. Gerald N. Johnson, P.E.); Date: Wed, 06 Jan 1999 10:26:19 -0600; I think the bigger problem will be leakage. Any leak from the transmitter BFO will be heard in the receiver. Any leak from the receiver BFO that gets past the filter will be radiated as a background; /archives//html/TenTec/1999-01/msg00088.html (8,592 bytes)
6. [TenTec] Omni VI chirp comment (score: 1): Author: n4lq@iglou.com (Steve Ellington); Date: Wed, 6 Jan 1999 12:51:28 -0500 (EST); By "freely running" are you implying that they never stop or that their frequency remains fixed? I assume the ladder. Throwing that capacitance across the xtal never seemed like a good idea since the; /archives//html/TenTec/1999-01/msg00089.html (8,812 bytes)
7. [TenTec] Omni VI chirp comment (score: 1): Author: JTBRANNIGAN@prodigy.net (JAMES T BRANNIGAN); Date: Wed, 6 Jan 1999 16:21:07 -0500; I've been following this thread for a while and did not understand what the ruckus was all about. I finally tuned into W1AW....and I must say that the CW sig is not the best I've ever heard....I also; /archives//html/TenTec/1999-01/msg00092.html (8,201 bytes)

Tip: When listening to an Omni VI, try both sidebands. One will usually sound much worse. The ARRL has been told about this several times but more input for listeners may help.

[TenTec] Omni VI chirp comment (score: 1): Author: w8au@sssnet.com (w8au@sssnet.com); Date: Wed, 06 Jan 1999 17:45:58 -0500; Right, Steve..... the old tried, true method (listen with a critical ear) is to switch sidebands....if you hear a "yoop" on one sideband you will hear a "bloop" on the other. This is a dead givaway.; /archives//html/TenTec/1999-01/msg00094.html (9,102 bytes)
10. [TenTec] Omni VI chirp comment (score: 1): Author: n4lq@iglou.com (Steve Ellington); Date: Wed, 6 Jan 1999 19:22:24 -0500; Yoop/bloop eh? I see your point but the Omni VI's chirp seems to have a different sound. I've heard them sound perfectly clean (except for the usual hard keying) then upon switching sidebands I hear; /archives//html/TenTec/1999-01/msg00098.html (9,945 bytes)
11. [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.
