I worked and have since been listening to J79WE on 40m CW for some time. The
wind is blowing about 40 mph so the power lines are acting up and I've been
tweaking the noise blanker.
While playing around I noted that his signal had developed some chirp. I
thought that strange, since he was clean when I worked him. I fired up old
reliable, my TS870 and listened to him and he was T9 with no chirp (and no
audio distortion). On the K3 he definitely had chirp, then I happened to turn
off the noise blanker and the chirp went away.
The Noise blanker setting were IF=MED4 and DSP=T3-7. The chirp seems to be
related to the DSP part of it.
Anyone else notice this?
