Guys,
So far I have received orders of total 4 beta kits. Please don't
forget to leave your address.
Thanks,
Adam

Tested OK. Modified a bit and ordered another batch PCB. You
can PayPal 9.9 USD each to rongxh@...
for the beta kits now, and I plan to ship by tracked air
shipping from Dec. 4.
Thanks,
Adam

Guys,
It is a FM/MW/SW radio receiver based on the KT-0936M(B9)
radio-on-chip. Stay tuned as I am about to receive the PCB
tomorrow.
And it is the prototype I built on my Choc board. I'd say the
performance is very impressive.
Thanks,
Adam

a more modern version of TA/CD2003 am/fm radio IC. For SSB RX, SI4732/SI4735 is a much better option imho.

It is a direct conversion receiver, Jim, so the short answer is, no. You could inject a signal close to it's dial frequency into the AM RF input, but you'd have to chase yourself up and down the bands. The architecture is actually quite similar to the (tr)USDX, with a CPU doing a lot of the heavy lifting. A very powerful chip, indeed!

Yep, that is the one!
Many thanks

John,
I think this is it. Working on my phone so please verify.

Have you got a link to an English language data sheet on the chip, Adam? My usual sources are coming up dry....

Could be a great kid kit.. ? does it do SSB?
Steve Pardon the brevity, sent from a mobile device. So there.

I haven't tried myself. I suppose it is not easy as the IF is not
exposed to us.

Hey Adam,
Cool !? I'll take a couple.? Can a BFO be added
for CW/SSB?

Re: ADX-S+ESP32(Bluetooth Audio)
Dear Mahesh,
Thanks for the test. ?I have tested on FT8CN and it worked.

Re: ADX-S+ESP32(Bluetooth Audio)
Hi Hitoshi, Thanks for sharing your work. I have successfully?tested FT8.reception with my homebrew FT8 TRX. I fed audio to ESP32 and wsjtx decoded signals using BT/HFP on W10, but the Pi-4 failed to detect it as HFP. I installed ESP-IDF and Btstack on Pi-4, after which I compiled and uploaded code to ESP32. I Need to modify the code to suit my mono band FT8 TRX based on nano. Attaching a few screenshots for?reference. I am yet to test it on FT8CN. Thanks & 73 mahesh-vu2iia INDIA
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.
For more information, please visit?
I am very sorry, but the document is written in Japanese.
Please use a language translation tool like "DeepL" to read it.

Re: PIXIE2023: One of the cleanest output Pixie?
You can try adding 120pF or 100pF cap in parallel to 1uH inductor in the LPF. The performance is not promised as it also relates to the bias but it should improve.

Re: PIXIE2023: One of the cleanest output Pixie?
Thanks Adam!
I understand that the modification consists in adding a capacitor.
What is the value and position?
