I've noticed that with my Omni VI (opt 3) on 40 meters I will clearly hear key
clicks from some stations, with what sound like true keying sidebands when they
are stronger than S9+10 or so, and keying with a bug or straight key. These
clicks or keying sidebands can be 5 khz away and still S9+, and are not nulled
by using the 500hz 9mhz filter.
There are some stations where I pick this up even if they are using a keyer...
So...question 1: can the use of a straight key or bug produce keying sidebands
or clicks if good solid contact is not being made (as sounds to be the case in
this situation); and
Is the Omni VI especially sensitive to the received CW wave form (perhaps due
to something in its AGC structure)?
I have listened with AGC fast, slow and off...and these keying sidebands and/or
clicks are still there.
So is it me...or just that many crappy signals on 40 meters?
