TICKING NOISE ICOM IC-7100
although no one ever commented on the ticking noise on air either
when I was on noisy HF bands or using crystal clear DV, in my ear phones with
the monitor on I could just about hear it when I connected to one of the DCS
This could be a problem with export model in
other parts of the world..
Some have cured the problem by buying a CAT7 cable, do another echo test and
see if ticking
Another solution: using an amplified
microphone, such as SM-20, SM-30 the ticking noise disappear
I tried to listen the noise with an external receiver (with headphone) and
with the internal monitor of the radio.
I have try also with an homemade Microphone with amplified circuit
Hookup non Icom Amp and I don't
hear the tick noise in the background.
Probably some components of the circuit filtering the noise.
