181. [TenTec] TT 705 Cartridge in headset-boom mike?? (score: 1): Author: geraldj@ames.net (Dr. Gerald N. Johnson, P.E.); Date: Tue, 12 Oct 1999 02:33:11 -0500; Using the electret mike element depends on its circuitry. Some already have just one output terminal (plus ground) and so have the bias applied to the output through a resistor. That means the resist; /archives//html/TenTec/1999-10/msg00315.html (7,635 bytes)

I fear the points of the coax connector might cause corona to break the glass though. In any case I figure there needs to be FEET of separation between the coax and th; /archives//html/TenTec/1999-10/msg00500.html (10,353 bytes)

That's a whole lot more liberal than most of the transverters that need a milliwatt or so. The input circuit is robust, I've not yet fried my 1209 with more power when I; /archives//html/TenTec/1999-10/msg00559.html (7,766 bytes)

Otherwise you will spend a lot more time digging amongst the stuff on the floor looking for those rounder parts. 73, Jerr; /archives//html/TenTec/1999-10/msg00563.html (7,358 bytes)
189. [TenTec] transverters for other bands (score: 1): Author: geraldj@ames.net (Dr. Gerald N. Johnson, P.E.); Date: Fri, 22 Oct 1999 11:09:55 -0500; I've tested the Tentec 1209 transverter and I found the PA stages are good from at least 10 MHz up to about 60 MHz. The broad band transformers are getting lossy at 70 MHz. I suspect they are good to; /archives//html/TenTec/1999-10/msg00582.html (8,482 bytes)

Johnson, P.E.); Date: Tue, 26 Oct 1999 13:03:06 -0500; Naw, silicon is quieter than tubes, more gain per device too. Tubes only sound quiet because of the low gain per stage. Everything else I agree with and I do like my Corsair II which hears much bette; /archives//html/TenTec/1999-10/msg00664.html (9,564 bytes)
192. [TenTec] I want a really good receiver (score: 1): Author: geraldj@ames.net (Dr. Gerald N. Johnson, P.E.); Date: Tue, 26 Oct 1999 17:48:09 -0500; Tentec does need to apply shielding to their radios. I think a good set of shields surrounding oscillator, signal, and synthesizer modules would do a lot good for making them quieter.

There's generally better front end selectivity so megawatt SW BC stations (except those on 7 MHz) are rejected better. 2. There can be narr; /archives//html/TenTec/1999-10/msg00763.html (7,810 bytes)
