We think so. During my time "in another place", some 12 miles north of here, I fitted hundreds of 500 and 270Hz filters in receivers for the keen CW man.
Given that the IF signal was stable and within spec after warm-up, I could not help but notice the change in timbre of the note as the filter got up to the same temperature as the radio surrounding it.
And this was after trimming up the carrier insertion frequencies.
AOR's filter tracking takes out not only this error but also acknowledges the manufacturer's own errors declared in their spec. This feature is most noticeable (and useful) in the narrow bandwidths but the assurance of sideband symmetry in the wider AM modes can only reduce phase-cancellation artefacts. Sorry - what I mean is, it distorts less and sounds better!
Hearing traffic on 5610 USB shows what a well set up sideband filter can sound like. AM Station AFN/AFRTS on 873 from Frankfurt is clearer now as evening falls, BBC Africa on 17830 has just faded out...
A call to PORTISHEAD RADIO on 4384 is very strong. 6950 may well be China, as could 6933. And possibly for the last time as we climb into higher Sunspot Counts, BBC Hong Kong on 3915.
That's the trouble with the AR7030. I have been asked to write a full technical review of it but all I've done is listen to it all day. And now they want to borrow it to see what I have got in the memories!
