 Coutil, I could only figure out two words of what you posted.
Most of us do not read or speak French.

Replying to myself here now that I've re-read Jim's post, looks like once the V5 code gets the V6 keyer, then all of my previous comments are mostly moot anyway... The new pins on the adaptor board take care of the keyer, and then PTT and key share the existing PTT line.  A6 becomes an open (digital or analog) pin.

Looking forward to the V5-compatible code, and your new Raduino replacement!

Jim,

You mentioned leaving the A6 wire disconnected... With a V5 board, I just need to NOT connect A6 to the resistive divider and/or pullup resistor for the CW key the way I did previously, right?  Granted, there will be some software modifications required for this, but my thought is:

- All I/O pins on Teensy 4 can be used as digital pins. so (unless you're using pins as analog in order to get more controls out of one pin, a la current uBITX) there's no need to use the pins in analog mode for inherently digital I/O.  (If I recall, one reason that the CW key is used as an analog pin is because it has to be, i.e. A6 and A7 on the Nano are analog-only pins, whereas this is not a Teensy limitation.)

- So, I can use two pins to solve all my CW and PTT needs, by tying their usage to mode, and then using them as digital pins.  So all of the ADC questions become moot.

CW Mode:
- Use key line as straight key input, or as dits for keyer
- Use PTT line as dahs for keyer

SSB Mode:
- Ignore key line (or maybe use as a tune button, i.e. straight key)
- Use PTT line as PTT

Future FSK/RTTY Mode:
- Use key line as "shift" indicator
- Use PTT line to transmit

I'd also note, for anyone willing to solder things to their Teensy, that there are an additional 10 I/O "pins" accessible via pads on the bottom of the Teensy 4. Ripe for taking advantage of the extra MHz on the Teensy to implement new functions...

Hi Thomas,

You need to use Chrome or a Chrome-based browser.  Vivaldi browser works fine on my computer.

Re: uBitx microphone wire up

Pin 1 - Ground
Pin 2 - Microphone
Pin 3 - PTT

Wire the ground side of the microphone element (one with connector fingers touching metal case of element) and one side of the PTT switch to Pin 1. Other side of mic to Pin 2, other side of PTT switch to Pin 3. 

This is the “conventional” wiring for 4-pin microphone plugs (and would accept a Cobra CB microphone). Make sure that your chassis connector is wired to match.

Thomas, et al,

"Spectroid" by Carl Reinke, or any audio spectrum display available for a smart-phone or tablet, works. While I applaud HF Signals for making a utility available for the purpose, it's chiefly just a graphic display of the audible sound range. 

You'll have to self-impose the 300 - 3,000 hz SSB window on the display, doing your best to set the BFO to fill that range more or less equally.  Me? I like to put just a little higher than lower by a thin margin so as to drop my voice lows and favor the highs,  for punch though the QRN.

Do you have a microphone attached to the device you are using to access the web page?  It will not work without a mic, and it will not give you a reason, just a static page without the graphics.

If you have a smart phone or tablet, those will work as well and will have a mic.

A simple variable voltage divider as on the v5 would bim the display. Thats how im settong my v5 with v6 screen

Evan -
The tuning aid site appears to be not working. I gather it is some sort of audio analyzer. I will try to find substitute. TNX for help.

All good points around cost. It will be interesting to see how the programming of the TFT goes. 

Things that would be great is a way to lower the current draw on the TFT perhaps a way to dim the back light. The current draw as is limits battery/field ops.

The nextion in bulk would be substansually more expensive than the one supplied with the V6. People will mod it close to the cec firmware though

Thanks Wayne. I will be using the mic element and switch that came with the kit. I understand that you cannot comment on the actual pins to connect to, but can you confirm that my thought process is correct and that the mic shares 1 of the pins with the ptt switch.

Re: uBitx microphone wire up

Wayne Leake
 

 While I cannot Tell you which pin to wire which wire to, it depends on the mike plug.
  I personally plan to use the 8 pin socket that a coupe of my radios use. And I have 2 mikes wired that way.
 One is a Heil Gold Line, dual element that I used on an older Kenwood, and will also work on another radio I have.
 Regarding CB and Ham Radio mikes, it is easy enough to replace the plug on it, or install one one a Mike that came without a plug.
 CB' s used many different plugs and sockets, from 4 pin to 5 pin DIN and up
 Mostly 4 or 5 pin I rewired a Mike from an older VHF Marine radio to work with an older Kenwood 2 meter rig.

Is there a mfr's extender board available that can plug into the nano/TFT board combination socket to extend display and nano combo board above the chassis box to be able to use scope probes and/or multimeter probes in live test/maintenance/research situations?
