Hi Clay,
This thread is a discussion about the relative performance of top-of-the-line modern transceivers in the most demanding situations faced by serious SSB contest competitors. The vast majority of transceiver users have no concerns about the performance of their transceiver under these conditions. We're discussing the most demanding situations affecting transceiver performance: weak -- often distorted -- SSB signals surrounded by much stronger adjacent channel QRM. For much of the time on 20 and especially 40 meters the adjacent much stronger signals overlap well into the receiver bandwidth. Typical spacing between SSB signals is only 1.5 kHz, if you're lucky its 2.0 kHz and only rarely 2.5 kHz or more. This situation is rather unimportant for the casual contester, but its a game changer at the upper levels of serious SSB contest competition. For transmitted SSB signals we're concerned about situations where our transmitted signal is relatively weak and surrounded by much stronger adjacent channel QRM. The adjacent signals usually overlap well into the transmitted signal bandwidth and the other operator's receiver has much lower performance that our top-of-the-line radio. 73 Frank W3LPL ----- Original Message ----- From: "Clay Autery" <k...@montac.com> To: elecraft@mailman.qth.net Sent: Monday, March 30, 2020 5:20:31 AM Subject: Re: [Elecraft] The Big Three... What is this "better" SSB performance of which you speak. I am primarily a voice guy.... And I am constantly complimented on the quality of my transmissions. How are defining "better" SSB performance? 73, ______________________ Clay Autery, KY5G (318) 518-1389 On 03/29/20 11:32, donov...@starpower.net wrote: > This is by far not an unbiased survey.
