1. [TenTec] S Meter Problem with Omni V (score: 1): Author: Frank Kirschner <frank@fkirschner.net>; Date: Sat, 18 Sep 2010 00:54:09 +0000; I just bought an Omni V with the N4PY mod. It works great, except for the S meter. I was told when I bought it that it was hypersensitive, and that is true. Is there a "most frequent" cause for this?; /archives//html/TenTec/2010-09/msg00146.html (7,698 bytes)

Looking at it I have found that there is an S-meter sensitivity adjustment R4; /archives//html/TenTec/2010-09/msg00147.html (9,412 bytes)

(Note to self: Don't assume.) You're absolutely right: all it took was adjustment. R45 was set at its highest; /archives//html/TenTec/2010-09/msg00148.html (11,244 bytes)

I wasn't going to fiddle with the R45 without having a true sense for what the actual signal strength was... Plus, the O; /archives//html/TenTec/2010-09/msg00153.html (12,757 bytes)

Re: [TenTec] S Meter Problem with Omni V (score: 1): Author: Frank Kirschner <frank@fkirschner.net>; Date: Sun, 19 Sep 2010 02:55:31 +0000; John, At some point I'll borrow a signal generator and set it up right. But it works OK for now. Thanks. Frank KK4PR _______________________________________________ TenTec mailing list TenTec@contest; /archives//html/TenTec/2010-09/msg00154.html (13,777 bytes)

How many Microvolts per S unit should it be set for? Can that be measured on the back of the meter or at the connect point on; /archives//html/TenTec/2010-09/msg00155.html (7,672 bytes)

Johnson" <geraldj@weather.net>; Date: Sun, 19 Sep 2010 10:11:53 -0500; The OMNI V manual says 50 microvolts RF at the antenna connection to show S-9 on the meter. Probably at 14 MHz. I have no idea what that is DC, probably half scale on the meter. 73, Jerry, K0CQ _____; /archives//html/TenTec/2010-09/msg00156.html (8,283 bytes)

NB off, AGC on and fast. 50 uV at the antenna port...Set for S9. Phil C. Sr. k4dpk _________________________; /archives//html/TenTec/2010-09/msg00159.html (8,912 bytes)

If like the original poster you don't have such a generator, you punt. 73, Jerry, K0CQ _________________________________________; /archives//html/TenTec/2010-09/msg00160.html (9,251 bytes)

In that case, he could depend on reciprocity and adjust for equal signals, while listening to someone running equal power and similar antenna. Phil C.

What I did was adjust it to be about the same as the meter on my TS-480. I basically wanted it to go to (or near) zero with no signal, and not peg with any distan; /archives//html/TenTec/2010-09/msg00162.html (10,353 bytes)

You have done fine, just use it. The factory calibrations were never any closer. 73, Jerry, K0CQ _______________________________________________ TenTec mailing list; /archives//html/TenTec/2010-09/msg00163.html (9,295 bytes)
