Seeing as my workshoop is in the garage, it will be a while for completion. Just too hot for the next couple months.
Anyone interested, the Teensy has native USB MIDI. It can also be programmed through the Arduino IDE for ease of use.
Most older transceivers have a switch matrix for the front panel ...

I am using the Mega for CAT/frequency/LPF switching. The VFD on the IC-765 is all controlled by 5VDC signals, hence the Mega (That I already have)

The Teensy 4.1 can take in the whole switch matrix system for all of the buttons on the faceplate with the pots/encoders added & has native USB MIDI.

I ...

Just for an idea, I have gutted an IC-765, except for the front panel, PA & LPF bank.
Inside will be:
HL-2
Mini PC
Teensy 4.1 (For gathering knob & switch settings & converting to MIDI.
Arduino Mega ( For gathering frequency & controlling LPFs & displaying frequency on VFD display).
Stil trying to ...

It seems that they are using Pure signal, too. I thought that was copywrite protected, too, as Simon (SDR-Console) will not even breach that.

Ed

That was my line of thinking. I was just hoping to get the TX state, along with frequency without polling the radio constantly.
Thank you very much !

Ed

I understand how the command works. I just do not know what the output will be.
I can change the bit 1-4 to get it broadcast how I need.
What I do not know is what is output. Is it just FA when the value changes?
Could it be configured to output "IF;"? The details are not easy to find.

Thank you,
Ed

Try running the rig directly to a dummy load, to confirm that it is the radio.

Some years ago Kjell Karlen and I made the "Odin" console which used CAT commands to control Thetis; implmented in an Arduino.

In case any of the code is useful, you will find the repository here:

https://github.com/laurencebarker/odin-SDR-console

Wow. As pertains to Odin, the code is written ...

It'll be a few weeks, if I am lucky. I sure will post it up. I collect lots of junk & sometimes combine some of it to make better junk.
I wish Thetis worked for the LimeSDR-USB, because, a 6M and up rig in an FT-726 is in the future.

Ed

**IMHO, MIDI is a lot of extra processing in order to form the required MIDI messages. Click a button or turn a knob one increment and puke out the appropriate CAT message seems simpler to me, especially if I was coding it.**

"Not" being a coder, I have found most of the "Simple" MIDI over USB ...

There will be no conflicts. Internal Thetis logic is "last command wins".

You might consider processing the analog controls into CAT rather than MIDI.

Note also that Thetis can accept CAT over IP as well as serial.

Excellent.
I used CAT for the processes that I did, because I already figured ...

My plan is to use all of the knobs & switches on the IC-765 to control Thetis. There are about 55 knobs, switches & buttons on the front panel & I will not have to use a label maker to remember what each one is.
I guess the "Story" was a bit long, but I thought the details may help.
Basically, I ...

**Next is to tackle the front panel/Teensy/MIDI. I figure that I can just make all of the buttons have different addresses & use Thetis to define them to their purpose.**
Of course, I am using Thetis. It is perfect for the system I am trying to build. The Teensy can be native MIDI_USB. Thetis then ...

I am stuffing my Hermes Lite-2, NUC, arduino, teensy, some level converter boards & such in an old IC-765. I have the Kenwood TS-2000 CAT operating the VFD for frequency/mode display, amp sequencing & band decoding with an arduino Mega 2560. I want to use a Teensy 4.1/MIDI for the front panel ...

Let me ask your setup.
Are you using an SWR/power meter between the tuner & antenna? If so, that is the wrong place to read SWR.
Try each band directly to the dummy load & see what the radio reads on all bands.

Ed

Some radios may be more sensitive to common mode currents.
Using a dummy load will negate those effects.
I would consider it the first step in diagnosis.

Ed

Back in the day, I used to find overheated components with Radio Shack Color TV Tuner Cleaner. Not sure if there is an equal in this EPA compliant world.

Ed

Thank you, Scott. This one gives me a comperable reading on my watt meter with the HL-2.
Good save !

Looks like his Github has gone private.

Ed

If I remember right, Simon uses CUDA & Open CL.
This was just one of my meandering thoughts, as I play with Thetis 2500 miles from my HL-2. Wish I had set it up for remote, but thought I was only going to be here for 4 days, not a few weeks.

Thank you,

I am just wondering why Thetis does not actively use CUDA cores from NVIDIA graphics cards to assist in processing?
I know that Simon uses them on SDR-Console & there is a big difference in CPU usage.
FFT can be shoved out to CUDA & leave the CPU to do what it's meant to, by my understanding.

Ed ...

I just tried it it pops up a window to reset your database along with saving your existing DB. Try it. You can always back out of it. Great tool to know.

Ed

Excellent ! That works.

If you watch this Youtube, I think you will understand my question better. https://www.youtube.com/watch?v=1LzOfLJYQCg&t=378s
Thetis is smaller on a black background that you can put the containers around Thetis.

Thank you,
Ed
WA4SIX

But, that just gives me the Desktop. RIchie has a black pallet that he can put meters on, which seems part of Thetis. I tried everything I could think of.

Ed
WA4SIX

How can I change Thetis size to put meters alongside main window, like in Richie's video?
Awesome work !!!

Ed

Check if your RIT is at 0?

Ed

I just set it up without connectin my HL-2 (2500 miles away taking care of Mom), the CPU usage is hovering at 3%ish. That's a 4 folld reduction, if I remember right.
On par with SDR-Console V3

Love it ! Spoken like a true Coder. Reminds me of a guy I worked with. He came in at 6PM & left at 6AM so he didn't have to "Deal with idiots". "Leave a sticky on my monitor".
Have at it !

Ed

Thanks from me, too. I'm still learning.
