1. [TenTec] Corsair II weak weak receive (score: 1): Author: jon greenwood via TenTec <tentec@contesting.com>; Date: Tue, 6 Oct 2015 02:40:28 +0000 (UTC); Hope some of the good troubleshooters on here can point me in a direction. I have a Corsair 2 that is very weak on receive. I have checked transistor voltages on IF/AF board 80984, the Osc/mixer boar; /archives//html/TenTec/2015-10/msg00022.html (7,810 bytes)

Re: [TenTec] Corsair II weak weak receive (score: 1): Author: Barry N1EU <barry.n1eu@gmail.com>; Date: Tue, 6 Oct 2015 09:20:52 +0000; It could also be a bad xtal filter or poor filter contact, or poor contact along the receive chain. Clean them all or try jumpering the filter contacts. Barry N1EU ___________________________________; /archives//html/TenTec/2015-10/msg00024.html (9,651 bytes)

No change. As far as the filters. I am looking at the 9mhz 2.4 It is a soldered on filter? everything; /archives//html/TenTec/2015-10/msg00025.html (12,302 bytes)

Re: [TenTec] Corsair II weak weak receive (score: 1): Author: Stuart Rohre <rohre@arlut.utexas.edu>; Date: Fri, 09 Oct 2015 14:25:11 -0500; Since one transistor position has the same incorrect voltage on all leads, I would look for a short. It might be solder splash on the under device side of the board. It might be a faulty coupling cap; /archives//html/TenTec/2015-10/msg00033.html (12,288 bytes)

The transmit and receive busses switch something that is throwing Q6; /archives//html/TenTec/2015-10/msg00034.html (8,797 bytes)
