The 160 Hz notch is about 12 dB deep. It is about 40-50 Hz wide. It is
centered at 160 Hz.
The following pictures were made using the SDR-1000 console. On the
test tab I turned White Noise on and made it the input.
I connected my transmitter to a dummy load ;-).
I set the transmit
I've been meaning and forgetting to ask who told you the eq notch should be
at 160 hz? All of my broadcast engineer friends say it should be centered
around 250 hz and be around -6-10 db deep.
Perhaps we should start a thread on the forum and get other pinions?

Presumably this issue is not a matter of opinion. Either there's a solid
technical argument behind it or there isn't.
As a general rule I'd suggest that (A) engineering errors get fixed in
the official

I was wondering that, too (why 160 Hz?).
I'd assumed it should have been either 180 Hz or 150 Hz

The short reason for selecting this frequency is that it tends to make the
audio sound boomy which is not desirable for amateur work. It is especially
troublesome
160 hz notch helps to remove that BOXY Yeasu sound which this radio does
have without eq.
I'm running 7 pieces of rack gear through my firebox and it works like a
champ.
I don't need the notch at all. Having udx and friends help with the eq cant
hurt anyone either.

OK, I've got to quibble with Jim's quibble. The first paragraph below implies
that one side of the line is grounded to the chassis. That was true back in the
AC-DC 5 tube superhet days, (as opposed to the rock group) but is no longer
legal because that would amount to having an exposed

There was a drawing on the page that clarifies that the chassis isn't
connected to neutral.
That was true back in
