7300?
7600?
Icom is selling the older radios at dumping prices because everybody wants the
new stuff (without manual notch filter).
I guess I should have said "every radio designed within the past 5 years"....
However it is indeed possible to have the auto-notch work within the AGC loop.
My little SKY-SDR QRP transceiver does and its notch depth is over 90 dB. It
can even notch out two-tone interference by that amount, leaving the SSB signal
on channel, free and in the clear.
And it does not turn on during CW because it would notch every dit and dah
completely out.

Every ICOM HF rig has a manual and auto notch. Unfortunately most are an
either/or proposition.

You guys are all out in right
field.
No radio's auto
notch filter works in CW mode.
They cannot
distinguish between the useful tone and the disturbing tone.
And yes, in that
case, a manual notch filter is indeed better, but show me a radio built
today that has one.
I find the Eagle's notch
filter effective on SSB.

"It's sort

I _LOVE_ my Orion II notch
filter!
The automatic
feature is good, but the manual one is about the best I've ever used.

A//B VFO, there really is no A or B VFO in the traditional sense and Eagle
only has one tuning knob. Therefore, the A/B indicator serves no function in
transceive operation. In split operation, that indicator should flip when
going fro RX to TX to tell you which displayed frequency is the TX frequency.
