It could be the filters. Unless an FL-52 or FL-53 455 khz filter is
installed, the radio doesn't work when switched to narrow. Take a
look at page 7-1 in the manual. It shows the various combinations of
filters, and which works when.

I've recently acquired an Icom IC-745 and I'm unclear on how it's

to work in CW mode. It does receive in SSB and AM, so in general the
receiver appears to work. When I press the 'mode' button to get it to CW
mode, however, it's just... silent. Actually, if I turn up the audio

gain,
there is some slight noise in the background. If I turn the squelch

(close
to) all the way up, the green 'receive' LED will go out and there's no
detectable noise coming from the speaker.

Any idea what I might be doing wrong here? I was expected that there'd
still be some hissing (background noise) coming from the radio even in CW
mode?

I agree also. You're probably missing the CW filter. However check your manual.
Every rig I've had with an optional CW filter had a way to route the CW mode
through the SSB filter if that filter was not installed, either by the menu or a
jumper.


Even if the CW filter is missing, he should be receiving CW through
the standard SSB filter.

Just switch to the "CW" mode, and make sure "CW narrow" isn't switched
in.

At least, that's the way my Icom 735 works. The 745 shouldn't be any
different.
