[Elecraft] dynamic range questions

[Geoffrey Mackenzie-Kennedy]

My pleasure Mike, my 3am "Autopilot" appeared to be working, maybe!

One final comment. The two in passband signal tests will tell you how a 
receiver will perform in use for example in a pile up situation where the DX 
station is not working split, whereas the wide spacing tests will only give 
you a hint. But you need very good test equipment.  As Bill W5WVO said in 
his post "at the end of the day it's dynamic range".  Once a large dynamic 
range has been obtained, then in CW receivers zero beat QRM stripping 
circuitry can be introduced - but that is another subject.
