1. [TenTec] Orion with AL-1200 -- QSK (score: 1): Author: nq5t@attbi.com (nq5t@attbi.com); Date: Fri Mar 28 18:05:29 2003; I need some help. The Orion manual is not very lucid on QSK connections. I presume the workings are similar to the Omni, etc., but since this is my first T-T radio, I'm not up to speed. My AL-1200 ha; /archives//html/TenTec/2003-03/msg00935.html (7,909 bytes)

[TenTec] Orion with AL-1200 -- QSK (score: 1): Author: k7kj@arrl.net (Greg Hodsdon); Date: Fri Mar 28 18:50:53 2003; Grant: You might try the Alpha 89 setup as outlined on the Alpha Power website at: http://www.alpha-amps.com/html/tentec.htm Greg Hodsdon Portland, OR k7kj@arrl.net http://www.qsl.net/k7kj -- Origina; /archives//html/TenTec/2003-03/msg00937.html (8,947 bytes)
3. [TenTec] Orion with AL-1200 -- QSK (score: 1): Author: w9ac@arrl.net (Paul Christensen, Esq.); Date: Fri Mar 28 19:34:54 2003; Be cautioned that unless your Ameritron AL-1200 has hot-switching protection circuitry, the mod as suggested above will likely cause hot-switching at the leading edge of transmission. You mentioned; /archives//html/TenTec/2003-03/msg00939.html (8,583 bytes)
4. [TenTec] Orion with AL-1200 -- QSK (score: 1): Author: w6ru@bak.rr.com (Terry Gaiser); Date: Fri Mar 28 19:44:21 2003; Wrong !!! Al-1200 has too much keying current to use that method .... Its states there that that hookup is for Alpha 87A & 89 amps only. Terry W6RU; /archives//html/TenTec/2003-03/msg00940.html (9,943 bytes)
5. [TenTec] Orion with AL-1200 -- QSK (score: 1): Author: wa3fiy@radioadv.com (WA3FIY); Date: Fri Mar 28 20:09:07 2003; That procedure at Alpha looks good to me. I've been using the AL- 80A with PIN T/R for over 10 years now with the Corsair, Paragon, Pegasus and Jupiter. That's exactly how I do it on all the rigs exc; /archives//html/TenTec/2003-03/msg00942.html (9,886 bytes)
6. [TenTec] Orion with AL-1200 -- QSK (score: 1): Author: w6ru@bak.rr.com (Terry Gaiser); Date: Fri Mar 28 20:19:36 2003; My correction ... I missed the statement that his AL-1200 has the PIN diode switching. Sorry... Terry W6RU; /archives//html/TenTec/2003-03/msg00944.html (9,872 bytes)

[TenTec] Orion with AL-1200 -- QSK (score: 1): Author: wa3fiy@radioadv.com (WA3FIY); Date: Fri Mar 28 20:20:36 2003; Paul, As far as I know, the PIN switch in the AL1200 is the same as mine in the AL80A. It is spec'd to switch in less than 500 microseconds. I have taken a very close look with scope and found the am; /archives//html/TenTec/2003-03/msg00945.html (9,565 bytes)

[TenTec] Orion with AL-1200 -- QSK (score: 1): Author: w6ru@bak.rr.com (Terry Gaiser); Date: Fri Mar 28 20:25:02 2003; Lee, The reason for the diode is to keep the source voltage from the amplifier and the transceiver isolated from each other in case one is greater than the other.

[TenTec] Orion with AL-1200 -- QSK (score: 1): Author: wa3fiy@radioadv.com (WA3FIY); Date: Fri Mar 28 20:33:56 2003; The Ameritron PIN-5 TR switch that I use draws less than 2 mA current and has open circuit voltage of around 12 volts.
