[TenTec] almost OT (involves Omni VI)

[atrampler at att.net]

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?
