1. [AMPS] Tentec Centaur (score: 1): Author: k4nr@earthlink.net (Tom Branch); Date: Thu, 10 Sep 1998 23:04:52 -0500; I'm looking at the Tentec Centaur--anyone out there using one? I'm interested in feedback on the QSK. Is it quiet? Tom -- FAQ on WWW: http://www.contesting.com/ampfaq.html Submissions: amps@contestin; /archives//html/Amps/1998-09/msg00129.html (6,561 bytes)
2. [AMPS] Kenwood TS450 & SB-200?? (score: 1): Author: k4nr@earthlink.net (Tom Branch); Date: Thu, 13 Aug 1998 21:33:24 -0500; Greetings, Just picked up an SB-200. The TS-450 has a 7-pin DIN plug to use for an amplifier, but no usable information (unless it's hooking up a TL-922--go figure!!) in the manual and the schematic; /archives//html/Amps/1998-08/msg00128.html (8,164 bytes)

[AMPS] Date Code SB-200 (score: 1): Author: k4nr@earthlink.net (Tom Branch); Date: Fri, 14 Aug 1998 18:32:52 -0500; Greetings, I was looking my SB-200 over and noted the model plate reads SB-201, serial number 01922. Was the 201 an update? Any way to know when it was manufactured? 73 de Tom, K4NR -- FAQ on WWW: ht; /archives//html/Amps/1998-08/msg00147.html (6,787 bytes)

What's the impact? I'd guess that if the Kenwood is producing full output when the relay goes that for a moment the SWR will go crazy; /archives//html/Amps/1998-08/msg00151.html (11,644 bytes)

(score: 1): Author: k4nr@earthlink.net (Tom Branch); Date: Mon, 17 Aug 1998 17:44:10 -0500; Greetings, Thanks for all the replies to my questions about the TS-450 and SB-200. I called the ARRL about their review of the TS-450. According to the ARRL measurements the TS-450 does the receive-t; /archives//html/Amps/1998-08/msg00164.html (9,023 bytes)

If the problem is simply (I doubt it...) the relay, why not just swap out the old one with something faster?

Still playing with the idea of full QSK for the SB-200. I ran across a circuit in the Hints and Kinks column in the April 82 QST. The cir; /archives//html/Amps/1998-08/msg00187.html (8,053 bytes)

[AMPS] Full QSK for the SB-200 (score: 1): Author: k4nr@earthlink.net (Tom Branch); Date: Mon, 24 Aug 1998 21:33:35 -0500; Rich, Okay--what about using the relay to handle the triggering of the cathodes? Would this decrease the rough audio caused by RF switching? 73 de Tom -- -- FAQ on WWW: http://www.contesting.com/ampf; /archives//html/Amps/1998-08/msg00190.html (7,467 bytes)

Took some time today to look at the input VSWR on each band. 40 and 20 meters are 1.0:1, 15 meters ranges from 1.4 to 1.7:1, 80 meters is over 5:1--seems l; /archives//html/Amps/1998-08/msg00210.html (8,876 bytes)
