1. R: Topband: Receiver Dynamic Range (score: 1): Author: Maurizio Panicara" <i4jmy@iol.it (Maurizio Panicara); Date: Mon, 10 Jan 2000 00:56:57 +0100; The bandwith of pulsed signals exists but actually most of the problem lay in the phase noise of the PLLs used in the transmiters that spreads some energy in the spectrum around the nominal frequency; /archives//html/Topband/2000-01/msg00077.html (8,761 bytes)
2. R: Topband: Receiver Dynamic Range (score: 1): Author: w8ji@contesting.com (Tom Rauch); Date: Mon, 10 Jan 2000 04:37:03 -0500; I agree with what you say Maurizio, but there are many other design problems that would be curable for a few dollars at the factory. There are two QSK related problems: 1.) Many rigs use the same VCO; /archives//html/Topband/2000-01/msg00078.html (9,024 bytes)
3. R: Topband: Receiver Dynamic Range (score: 1): Author: k6xt@arrl.net (Art Charette); Date: Mon, 10 Jan 2000 12:49:07 -0800; Tom, please don't stop there. What was the dollar spent on?? Did you get rid of the 775DSP? My 781 probably uses a similar scheme but, except for crossband like JA, I use RIT/TIT for splits under 10K; /archives//html/Topband/2000-01/msg00082.html (6,941 bytes)
