[TenTec] O2 sidetone... RST 599C

["John B. Egger" <john_egger@comcast.net>]

On occasion (like tonight) my sidetone seems to have a bit of a chirp. A 
few days ago I fired up the old Century 21 (no antenna connected) as a 
monitor and the signal sounded perfect, much better than the sidetone 
coming from the O2' s speaker. At other times the O2's sidetone is clear 
as a bell.
I've had this rig just a bit over a week and really like it, but I'm 
still way down low on the learning curve. Has anyone else noticed this 
sidetone? A search of the archive shows clicks as an occasional 
problem... but my sidetone is 599C, not 599K.
