[Elecraft] The Big Three...

[donovanf at starpower.net]

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.

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,
