GM Billy,

In reading back over my post, I did not find a mistake but rather a sentence
that was written poorly and might be interpreted two ways; one right, the
other would be wrong.

Is this the mistake that was referred to in your email?

"" We can do something against the broadband noise.  By inserting a
high-power bandpass filter in the antenna line such as a Dunestar, ICE, or
similar, we can reduce all interference (including broadband noise) by about
40 dB.  So with filters, many of the radios with a marginal broadband noise
problem are indeed usable in a multi-TX environment. This includes the
590.""

I should have said by inserting a bandpass filter in the antenna line *of
the transmitter causing the noise*, we can reduce all interference...

In the case of broadband noise, a filter on the receiver does not help
because the noise also falls within the bandpass  of the band filter.

If that is not the mistake you were referencing, then please help.
That was the only line where I was referring to BPF - I think.
