1. [TenTec] Corsair II tuning (score: 1): Author: Paul DeWitte <k9ot@yousq.net>; Date: Sat, 25 Aug 2018 12:17:39 -0500; I am not sure how to explain my problem. I have 3 corsair IIs. recently I got one out to give it some air time. It had been a while since it had been used. When tuning in a signal on 40M I found that; /archives//html/TenTec/2018-08/msg00186.html (7,217 bytes)

Instead of subtracting in a mixer of the PTO and crystal as it does on most bands, it adds on 40 so tuning goes the opposite direction. The counter pr; /archives//html/TenTec/2018-08/msg00187.html (8,345 bytes)

Re: [TenTec] Corsair II tuning (score: 1): Author: Carlos <carlos.peco@gmail.com>; Date: Sun, 26 Aug 2018 08:40:45 +1000; Hi Paul, It might be that somebody repaired the radio fitting a different Xtal to the heterodyne oscillator (maybe the original one could not be sourced?), as there are two combinations of VFO ranges; /archives//html/TenTec/2018-08/msg00188.html (9,164 bytes)

Re: [TenTec] Corsair II tuning (score: 1): Author: Duane - N9DG via TenTec <tentec@contesting.com>; Date: Sun, 26 Aug 2018 19:07:47 +0000 (UTC); A test that would be interesting to see is if the behavior of how the CW signals tune behaves the same way when the mode switch is set to SB-N and then SB-R. They should behave differently from each; /archives//html/TenTec/2018-08/msg00190.html (9,688 bytes)
5. Re: [TenTec] Corsair II tuning (score: 1): Author: MadScientist <dukeshifi@comcast.net>; Date: Sun, 26 Aug 2018 17:47:45 -0500; On 160 meters, the PTO (5.0 to 5.5 MHz) adds to the 5.8 MHz crystal to produce 10.8 to 11.3 MHz. The the 9.0 MHz IF is subtracted from this signal to receive the incoming signal (2.3 to 1.8) MHz. On; /archives//html/TenTec/2018-08/msg00191.html (14,636 bytes)

Re: [TenTec] Corsair II tuning (score: 1): Author: MadScientist <dukeshifi@comcast.net>; Date: Sun, 26 Aug 2018 20:28:02 -0500; The Corsair II automatically selects the most popular sideband for a given band. Thus, one automatically gets USB on the higher bands and LSB on the lower bands when you are set to the SB-N position.; /archives//html/TenTec/2018-08/msg00194.html (19,399 bytes)

Re: [TenTec] Corsair II tuning (score: 1): Author: Carlos <carlos.peco@gmail.com>; Date: Mon, 27 Aug 2018 13:00:59 +1000; Hi Gary, I have never used the radio in 10 meters, so I wrongly assumed that it was like in the rest of the bands. I'll find out later today (I just bought a 1210 transverter) Thanks for the note, ve; /archives//html/TenTec/2018-08/msg00195.html (17,158 bytes)

Re: [TenTec] Corsair II tuning (score: 1): Author: MadScientist <dukeshifi@comcast.net>; Date: Sun, 26 Aug 2018 22:14:24 -0500; I forgot to add, the reason why 9m MHz IF radios automatically select LSB on bands below 9 MHz and USB above 9 MHz is that, back in the 1960s, 9 MHz was a very popular IF because the manufacturer cou; /archives//html/TenTec/2018-08/msg00196.html (9,274 bytes)

Re: [TenTec] Corsair II tuning (score: 1): Author: Steve Hunt <steve@karinya.net>; Date: Mon, 27 Aug 2018 09:24:24 +0100; Using a 9 MHz IF conveniently gives you 80m and 20m coverage from a 5MHz VFO without the need for heterodyne crystals; however it does _not_ produce a sideband inversion. What happens is that the tun; /archives//html/TenTec/2018-08/msg00198.html (11,323 bytes)

Re: [TenTec] Corsair II tuning (score: 1): Author: Steve Hunt <steve@karinya.net>; Date: Mon, 27 Aug 2018 09:34:31 +0100; I should have added for completeness that it's a 5MHz IF with a 9MHz VFO mixing arrangement that produces a sideband inversion between 80m and 20m. It also does away with the tuning inversion. Steve; /archives//html/TenTec/2018-08/msg00199.html (9,621 bytes)
