[ICOM] 756PRO3 - popping sound?

[Bert Almemo]

Hi guys,

The following message came in on another reflector. Anyone heard of this
problem on the PRO3?

The original Icom 756 Pro receiver had an anoying popping sound that would
show up at the start of each morse element when listening to strong CW
signals.

The 'pop' was mentioned in the QST product review in 2000 as as
"characteristic of direct conversion receviers employing audio-based AGC
systesms" and "the pro has a habit of introducing pops on the make of each
CW element".

Before purchasing an Icom 756 Pro III, I was told (by Icom) that the
'popping' issue was addressed, but that's not the case. The problem still
exists and is especially obvious with fast AGC settings. It's not too bad
with the internal speaker, but it certainly shows up with headphones and
some external speakers.

Suggestions appreciated...
