Stereo CW on the K3?

Apologies if this has been mentioned before...

One of the things I _/really/_ love about the KX3 is the stereo panning
of CW signals low to high pitch. It makes reading CW so much easier
especially during contests.

Is there any chance that feature can be incorporated into the K3's
firmware sometime? The K3 is perhaps more of a contest radio than the
KX3 and this is one area (it seems to me) to be deficient.

Re: Stereo CW on the K3?

What -- they implemented this first on the KX3 and not the K3? I
remember discussing this in the FT days of the K3! Come on, guys...

I enthusiastically second this motion. Before I got my K3 a few years
ago, I rigged up a pair of old Autek QF-1A filter boxes with some Rube
Goldberg relay switching to do this using my FT-1000D. Since the FT1K
uses USB CW, I set the right ear filter up as a low pass and the left
one as a high pass with the 3 dB down point of each one at my preferred
beat note. This arrangement made it easy to quickly center an
off-frequency signal by rotating the main tuning knob in the direction
of the ear toward the desired signal. It was really a great tool,
particularly for running in a contest situation. I found it very useful
even with a 500 Hz bandwidth and really good when I widened the bandpass
out to 800 Hz or so.

When I got the K3 I just reversed the HP and LP filters to accommodate
the LSB CW tuning. I also began doing more serious SO2R work using the
FT1K as the second radio. For various reasons, mostly having to do with
needing to throw too many switches every time I use the second receiver
in the K3, I rarely use the panoramic audio setup now, but I do miss it.
I had hoped that some of the various AFX modes of the K3 would be
useful, but never could get them to do anything I found as useful.

What would really be great would be a built-in panoramic audio mode that
automatically turns off whenever the second receiver is activated. I'm
not a DSP guru, so it's possible what we're asking for would be a real
bear to implement separate HP and LP filtering in the two audio
channels. If it's really already being done in the KX3 this suggests
it's doable and is really good news. I'd sure like to see the same
capability in the K3.

The K3 had it first - try setting AFX MD to BIN.

BIN mode on the K3 does simple 180-degree phase reversal, like the phase-reversal switch on some headphones. This can reduce operating fatigue if you've been on the air for a long time.

PITCH mode on the KX3 actually maps pitch linearly from low pitch (left audio channel) to high pitch (right audio channel), which can help the operator separate signals in acoustic space. It may be possible to add this to the K3, but it uses a completely different DSP, so we'd have a lot of work to do in porting the algorithm. I believe this is already on the wish-list.

The Timewave DSP-599zx also has a similar stereo panoramic feature.

Re: Stereo CW on the K3?

The Ten-tec Orion has a really good implementation of binaural CW. With headphones on, you can literally “see” the position of a particular CW signal from left to right. I always found it amazingly effective and useful. I no longer own the Orions or Orion II, but I do miss that feature.

I’d love to see it on the K3.
