KC9ON has 20 meter crystals - 14.050, 060, 070

BTW, my new PIXIE 2023 converted to 20 meters is doing a super job!? The above website?tells of the small changes to convert to this band.? Also, I changed to 2N2222 as the final.? ?73's N9EGT

Re: ADX-S+ESP32(Bluetooth Audio)

#4566

Incorporating a TFT (display) the LEDs become redundant.?

Using the power of the ESP-32 for decoding purposes makes it a truly stand alone unit.?

In ATS-25 it's already been demonstrated that, one can decode these signals using the ARM core, then why not think on these lines.?

Using an ESP-32 for only replacing the Arduino, in my opinion is an over kill.?

IMHO, let's not be in a hurry to design a new pcb yet.?

Can we further look at features offered by ATS-25 Rx into this project.

Specifically , decoding of FT8 by the ESP32 itself. The ATS-25 decodes FT8 , CW and maybe RTTY using this kit.

I modified the ADX-S and replaced the Arduino Nano with an ESP32 Devkit.
The ESP32's bluetooth audio (headset profile) allows wireless connection to a PC.

These PH2222 transistors are rather old, but they just performed very well. Please share with me your result. Have you tried some transistors on hand?

The mod is necessary if you wish to stay at marked frequency on crystal.
