G'day Gentlemen,
I don't think it is "branding" when pointing out a problem
with someone's signal. It happens to all of us and we need
to know when our signal is not right.
N4IS called me once that I had two weak spurs about 3 kHz
from my carrier. I could not detect them at all on my
second RX, or see them on my spectrum analyzer. We started
troubleshooting and soon found the problem: two burned out
resistors in the K3's PA. (Resistors in the feedback loop
can burn out and cuase the bias circuit to oscillate -- K3
owners please be aware!)
Another time, I was really insenced at this strong station
with very storng clicky signals, just to find out that I
did not have my AGC set correctly and the clix were
generated in my own RX! Ooops! Good that I checked first
before making a comment.
I have also heard, however, during a contest, a station
with strong clicks he normally did not have. Deliberate?
Perhaps to keep "his" running frequency clean?
Perhaps he has just turned his drive a tad too high in the
excitement. Pointing the clix out to him should not hurt
his feelings, I recon.
We get all kinds of reasons for poor signals and the
sooner we let each other know the better. The band is a
precious and limited resource, we need to keep it clean. I
sure will not be upset if somebody lets me know!
Of course, intentional jamming, that is an entirely
different subject, but...
