Am-Com Clear Speech CSS-II (has built in speaker)

[AF6EC]

I just acquired this unit and it does do a great job of noise reduction but there is always a low level of what sounds like several conversations in the background. This is occurs whether or not a real signal is being received. I would like to know if this is normal for this unit. Also the green pilot light is out. Is this hard to access and replace. Lastly, does anyone know where a manual can be obtained for this unit.

Thanks for any help.   Jim   AF6EC

The low level noise is normal. In fact even if you just has power running through it you will hear
 the noise.  I first thought there were a bunch of baby birds making noise in my atic.  I have no input on the pilot light.

Jay,  Thanks for the response. I feel better knowing the noise is normal. Other than that, it is an amazing product. I am surprised it is no longer being made. I think I will search around for another one as a back-up!

That low noise is normal, yes. It's just artifacts from the DSP.

I have the instructions somewhere for mine. But IIRC, it didn't say much of anything useful.

There is another like it, but I don't know who makes it. Unlike the old Am-Com ClearSpeech, it has multiple level settings. But I have no idea how it compares.

Seems like there was an article in QST last year that explained how to make one.

Jim, West Mountain Radio now owns the patten on the speaker and  I think speakers and is selling them for around $220.00 a copy.  Like you I think this is the best noise reducer out there.  I did buy a second one as a spare and after 10 years I did have to put it into service

Jay, You are absolutely right about West Mountain. Good to know these are still available, I was told they are no longer being made.

And thanks also to W0BTU.

I now hear stations that I did not even know were there before!
