A good concept. Looking though the web searches, there's some feedback to that
point. However, where you suggest would put you up with some other offenders,
particularly RTTY. I don't think it matters where you go, you'll still get
stomped on if your QRP.

Simon, is this a good example?
Being as fair as I can I suggest that this is not an over-driven signal,
he's just strong. DM780 5.0's enhancement option will really help as would a
500Hz filter in the 450 if possible.
If you're thinking about a new radio look at the TS-480SAT - IMO the best
digital-mode radio.

Yeah, I figure most signals I see, particularly PSK, aren't over driven, as the
trace looks clean, but my rig's notch capability isn't what I'd
Hi,
Keep an eye out for a second-hand 480SAT - I've heard of them going for ~
$500.

The 480SAT is certainly a fine rig, as Rob, AA6A would attest, but another

I also find that using a combination of narrow filters and passband
tuning helps dig out the weak ones in the presence of strong stations.
I've been using an IC-7200 for the past few months. It's Twin Passband
Tuning feature of the DSP lets you electronically narrow the IF
passband. Very

The enhancement looks very interesting. How do you do that?

Skip makes a good point. Passband tuning and IF shift are effective in
dealing with AGC capture.
In some cases I have added attenuation in to the receiver as an additional

The only remedy is proper filtering as early in the chain as possible, with a
