Re: Conversi¨®n v5 lcd a v6 tft
Jack, I fully understand what you are saying.
The issue is that in the original firmware of Ashar Farham nowhere makes reference to the library of the tft screen.
That's why I'm so puzzled.

Re: New kit: QDX - Digital Transceiver by QRP Labs
Hi Rafael
As Jerry said... It's a matter of optimization. Most currently popular ham digi modes are sequential FSK modes (single carrier). FT8 accounts for more digi mode activity than all the others put together. A good SSB rig is a more complex and costly transceiver and that's what's needed for multi-carrier modes.?

Re: Conversi¨®n v5 lcd a v6 tft
Mario:
In my Open Source code, I will often add something like:
#include <Rotary.h>???????????????????????????????? // https://github.com/brianlow/Rotary
The "//" means that, whatever follows, is a comment and is ignored by the compiler. However, I use it to tell the reader the URL where they can go to download the Rotary library. Perhaps your code is doing the same.

Re: Conversi¨®n v5 lcd a v6 tft
Which TFT library are you using? Make sure you match the library to the driver on your display (e.g., Adafruit_ILI9341 to the ILI9341 driver used by the display).

Now hear stations the same as with the original processor.? Transmit works with the mic.? Paddle doesn't work (plugged in the front jack on the right). My guess is the calibration "X" locations are set incorrectly in the software. Nice software and user interface.? I really like changing the frequency tuning step.? Calibration seems more precise.

I bought one used unit that the previous owner reported as not having good reception and birdies..?
The problem was that the side bands were reversed.?

Paul, You didn't get it calibrated properly for some reason.? Be very careful - make sure the lower right corner of the screen isn't shorting to the metal case as that will cause weird things to happen with the touch screen.? You need 4 x's touched for proper cal.? Top left, then top right, bottom left bottom right after bottom right it should go to normal screen.? You might have bumped the screen right after you hit the third x.? That is about the only thing that would cause that.? Try it again, make sure you get all 4 x's.? If not and you can't figure it out, send the board to me WITH the display and I'll fix it - no cost other than shipping.

Albert,
TP20 is the audio input so thats why your birdies vanish.
It is very odd, I think you have a grounding problem.. please check.

The birdies are very strong (loud), they are comparable with an input signal of -70 dBm. When I short the input of the BFO mixer (CW-2) the birdies are still there, but when shortening the output of the BFO mixer (TP20) they are completely gone, is it possible that it is injected via the clk#0 signal (mixed with clk#2)?
Any idea what to try next? Currently I only have a scope and signal generator and HF RTL-SDR, but I have ordered a tinySA.

The mandatory files were needed for another version - try programming it with the Teensyduino add on as is and if it doesn't work, then those files need to go in the "hardware/teensy/avr/libraries/" directory.? I think PJRC has included them in the latest "Teensyduino" add on.? You should also download and install (In it's own directory, don't use windows installer) it before you install the Teensyduino.? Tell the Teensyduino's installer which directory you installed Arduino 1.8.16 in and that should take care of it.

Hi Jim,
I've got everything completed, the TSW board and the teensy headers soldered on.?
Now how to program the teensy with your program?? Do I use the add-on for the arduino IDE?
Also I noticed on your website there are needed.? Where do these files go?
Sorry if this is detailed somewhere....? Newbie here.

Re: New kit: QDX - Digital Transceiver by QRP Labs
Exactly.? A non-linear power amp allows it to be optimized
for it's intended purpose.? It does not attempt to do everything.
If you need multiple simultaneous tones, there are dozens of
SSB transmitters you can choose from.??
But they won't be as cheap or as efficient with the power supply.

Also, a reminder about 1206 devices ¡ª if you are doing a ¡°dead bug¡± project and need a passive component across two adjacent pins of a 0.1¡± spaced DIP IC, a 1206 device fits perfectly. They¡¯re also easy to solder if you first clamp one side of the 1206 with spring tweezers and solder the other side.
You¡¯ll be pleasantly surprised at how easy this is and perhaps more importantly, how much space it saves.

QDX does sequential tone FSK modes. That includes WSPR, FT8, JS8Call,
JT4, JT8, JT65, RTTY and others.?
MFSK is also a sequential tone FSK modes so MFSK is OK.?
I lost count of all the different digital modes but MFSK, sequential
FSK, is what works on QDX - which is not EVERY digital mode but
certainly covers many (the majority?) including the world's most
popular FT8.?
Phase-shift keyed modes like PSK31, are not currently supported; any
modes involving multiple simultaneous tones in the SSB channel are not
supported; and CW is not currently supported. Yes you could make it do
CW but since there isn't any RF envelope amplitude shaping you'd have
a horribly clicky signal.?
