New DSP features?

Administrator

Hi all,

The K3/K3S and KX2/KX3 are SDRs, by definition, because they provide demodulation and modulation features via a DSP chip that is programmable.

Our DSP algorithms already give the user all the usual features expected of an all-mode transceiver, and then some:

- DVR
- variable passband filtering & IF shift
- audio peaking filter (APF, for CW)
- auto-spotting and automatic tuning (CW, PSK)
- dual watch (KX2/KX3)
- audio effects
- DTMF (KX3)
- dual-passband filtering for RTTY
- FM subaudible tones
- data decode/encode in various modes
- noise reduction
- RX and TX EQ
- synchronous AM (K3/K3S)
- ESSB
- transmit noise gating
- speech compression
- manual notch filtering
- autonotch

...etc.

That said, here's your chance to dream up *new* DSP features we haven't thought of. All suggestions will be debated by our engineering team, even those that appear radical or implausible at first glance.

We'll keep this to ourselves, so don't worry about being judged for tossing out some wacky ideas. Let's cast a broad net.

Please send all correspondence on this topic directly to yours truly.

Thanks for all the many great suggestions and digressions, folks. Sorry I can't respond to all of them right away.

My favorite so far is the request for Semantic Filtering Mode (SFM), which "might, with skillful adjustment, suppress political commentary from 75 meters." Our DSP IC does include odd/even partisan check bits, so this is a SMOP.

Runner-up is a proposal for auto-detection of unattended FT8 transmissions, i.e. the "No One's Home AlarM" (NOHAM).

Feel free to pile on, at least until Eric puts the hammer down.

I love that one. Along the same lines, a broad brick-wall notch that auto-detects the recurring clown show on 7200 KHz would be a welcome addition ... especially if it could auto-suppress music.

Grant,

Just turn the VFO knob! It works.

Might I suggest a filter that translates a bug user who sends at 15wpm, but
the dots are set to 35wpm. The filter would briefly store the cw, correct
the timing, and then pass it through the audio stages. Call it the
VibroDummy, or VD1 filter setting.

Another one would filter out the long "annnnd uuuuuhhhhh..." of VOX users
who only transmit 50% or less of transmit time as intelligible speech,
remove the non data periods, then pass the compressed version on. Call it
the VoxDummy, or VD2 filter.

Finally, introduce NR so sophisticated it automatically finds the correct
tuning soloution, requiring another 4 cu ft of room inside the K3 for
microprocessers and memory. Release it in a bloated, gigantic case, add 50
controls to the front panel, and call it a K4, thereby silencing two sets
of critics who post--but do not read--on the reflector.

Best post of the year!!! I will be chuckling at that all night; yet, you delivered exactly what Wayne asked for and we all wish our radios had. You even gave the K4 speculators something to chew on for a while. I will go to the gym tomorrow to start building my arms and legs to handle my new KX3ss! The "ss" is for supersized!
Great stuff!

Sounds like a project for a neural network. A bit of AI which
'recognizes' patterns. There would be ~ 40 outputs for letters,
numbers, and symbols. I am unsure of the number of inputs nor of the
middle layer(s) of the net. But that's just a bit of engineering.

The training sets would consist of a large set of "Lake Erie swing
music" and expert interpretations of it. Find a large computer and
spend a few weeks training the NN.

There are some shortcuts I foresee. Quite a few characters can't (?) be
messed up by the misuse of a bug. T, O, M, etc. Those don't really
need to go through the NN so you can save on the number of outputs and
decrease the training time significantly.

The neat things is once you've done all this work you can put the
trained NN into a very small space of code. And use a moderate number
of processor cycles.

Not quite DSP but AI is just another acronym :)

There is an AI joke somewhere in here about a dummy load....

I like the way the KX3 will let me use the automatic spot on the receiver only when the RIT is on. I have always wished the K3 and K3S would do the same thing as the automatic spot works so well but I do not want to move the transmitter at the same time with the RIT on.

That is the only thing I can think of as I love my K3S.

Bob McGraw - K4TAX

Re: New DSP features?

And for this reason I choose to use SPLIT in CW mode as opposed to RIT.
Thus SPOT only affects the received signal frequency which is VFO A and
I can tune VFO A as needed just like RIT. Thus VFO B is always the
transmit frequency and is not affected by the SPOT function.

Re: New DSP features?

In reply to this post by wayne burdick

I find the NB in the K3 is very versatile and can usually make a difference.

I rarely use the NR, never found it much use, that goes for other rigs
too, might just be me.

The APF was a great addition to the K3 firmware but I feel it could
stand some enhancement, adjustable BW would be very nice and something
to offset some of the artefacts I feel it adds as it is right now.I
don't think it needs adjustable centre freq for use as a CW peaking
filter as only the one freq is of interested. When the Orion added APF
to its firmware it was variable from 300Hz down to 10Hz with adjustable
centre frequency. Not so much for CW but a surprisingly useful SSB
addition. Much like a sweepable EQ it can often be just the thing for
enhancing a rough voice signal down in the noise.

Better decode capability for some of the more recent digital modes, FT8
would seem an obvious one but how? Maybe on screen with a P3?

Has DSP hardware advanced significantly since the K3/S was designed?
Maybe a replacement module with more recent DSP devices might allow even
more possibilities. But maybe that's K4 land :)

Re: New DSP features?

In reply to this post by wayne burdick

Not really DSP, but firmware related. I would like to see a CW Tuning
Indicator on the SVGA monitor attached to my P3. I use a KPOD and
keyboard macros when I S&P in contests, and the rig is off to my side
where I have to turn my head to see the CWT indicator. The SVGA monitor
is in front of me. I don't know if the refresh rate is fast enough, but
I'd give up a bit of real estate in the waterfall for this feature.

If it's already available and I haven't found it yet in the settings, my
bad.
