Interesting,
So, given a decent mic insert the overall audio response is very much
coloured by the housing of the the insert...
Close talking a mic gives a better S/N ratio, less background noise and
room colouration, but yields too much bass due to proximity effect?
How to overcome too much bas

Proximity effect is not limited to dynamic mics. But it seems to be
more common with dynamic mics used for amateur service because the
electret has both a higher output level and more low end to start with.

Thank you Joe, I have been looking for an explanation of most of what
you covered here for several months. I'll pass it on to my buddy that
mentioned the "Icom sound"!

insufficient carrier suppression (carrier leakage). Signal to the
left of that is generally insufficient opposite sideband suppression
(sideband leakage) or regenerated sideband due to excess IMD in the

I have also noticed this, is the robotic sound you are referring to a
low frequency sort of "wha wha" sound which modulates along with the
normal voice signal.
I have heard this before as well, and had a friend describe it as
"typical Icom", which leaves me in the dark about what it i
Hello everybody!
Ever since i got my new P3 - i've been looking at people's signals (naturally).
And i've noticed the following:
When using USB on 10 meters, talking locally, there are a couple of folks that
use ICOM radios and i can see these spikes on the left of the carrier.
Normally, in USB, a
