Jerry: The key to a solution is the last sentence: The feature set of the ?BITX has outgrown the processor and it's time to leave the ATMega328 behind. While I have my own preferences, I think we

Part of the CW problem is that there are already many uBITX out there in use which could use an upgrade. This involves replacing the whole Raduino if we want to upgrade to a larger processor. Ideally

Absolutely right, the Nano is overloaded, and i2c writes to a display slow it down further. However, sending CW is reasonably slow, even for a Nano clocked at 16mhz. Lets assume we are shooting for

I haven't gotten around to powering up my V6 yet, but I think my solution will likely work the best:? rework the Nano's program to remove the keyer portion, then use a Hamcrafters K44 external keyer.

Hi, I went back to using an external keyer just because of the clumsy operation of the built-in keyer in my V3. The uBitX then sees straight key operation regardless of what is outside the radio or

If we were all the same, would it not be a VERY?dull world?

Jerry KF6VB, What is your WPM setting when doing the tests?? Does the error rate change with the WPM speed setting? The reason I am asking is to see if it is related to the increased load on the Nano

Because with you doing all the real trail-blazing development for us Farhan, the rest of us have far more time to devote to the more trivial aspects of life, including spell-checking, calculation

Yes, using various voltage levels into an ADC was done because of no remaining pins on the Nano. Best to choose a processor with enough pins for the job such as the RPi-Pico that Farhan has been

I am not a "CW Op"...barely able to walk and talk sometimes. 8-) I must admit that using voltage based switching via an ADC would not be my first choice for generating CW. The ADC in an AVR328 has

Hi Arv, It's the factory uBITXv6 software. Slightly modified as to tuning rate, but nothing that would affect CW. Apparently, the paddle input is an *analog* one. Three possible voltages are produced:

Which software are we talking about? Is this an RF interference problem, or possibly a race condition in software? Arv _-_

The v6 voltage divider pulls at different strengths for dot and dit. If you try and send a symbol that is the stronger pull, there's a small window on the way up and down where the voltage will be at

Hi Reed, The wrong *time*? I am confused. Is it a successive-approximation A-D? I just hauled the Bencher out to the garage and cleaned the contacts with De-Oxit and lacquer thinner. Now seems to be

Yep. That's because the hardware implementation is a voltage divider, and if it happens to sample at the wrong time, it will catch the intermediate state. Reed

It seems that - just occasionally - when you hit the "dit" paddle, the thing will go "dit dah", instead of just "dit". - Jerry KF6VB

Hello all, Practicing CW with the v6, a dummy load, and a Bencher paddle.... I seem to be making more mistakes than with other systems ( e.g. a Kenwood TS590S ) and the same paddle. There's something

I made a few changes to the firmware which some may like, so I am posting my changes here.? Also, there is a small bug in the sideband selection code that seems also to exist in the v5 and v6 stock

All, So with all the fun with playing with the firmware on my uBITXv6, I blew away the factory calibration, and had to redo it. I used the BFO alignment aid ( what a wonderful tool! ) and my radio is
