Great setup and video, thanks.
Is this Century Park? Have been close to it several times but never had a chance to visit.
I like to visit the market in the underground station of the Science and Technology Museum metro, next station is Century Park.
Next time I'll have a walk in the nature ad stay away from those tourist's alleys.?
Thanks again, regards

Alberto,
You are familiar! The place is actually where I am living, very close to the Century Park which is 10 times bigger and more beautiful. I do POTA mostly in the Century Park. You can find more videos on my YouTube channel.

Guys,
You probably have noticed that I have upgraded the camera to DJI OSMO Pocket 3. I did not use the wireless microphone and I think it is helpful to hear me all the time even I am not in the camera.?

Matt,
I saw your video demostrating FT8CN and ADX-S V2 on 40m band. The
9V battery looks cool.
Thanks,
Adam

Hi Adam,
I crashed a couple of Nano Arduinos. I don?t know why. The newest one I use? is with a mini usb Plug, a little bit thicker than the USB-C, But everything is o.k. It works, as you can see :) . I got some QSOs with the USA and Japan, using the ADX-S es a Magnetic Loop antenna :). Seams to be caused by the bluetooth device, the ADX-S V2? is more sensitive against HF and there is a danger to destroy the Arduino rather than using an audio cable.?

Matt,
The key is the C25. It helps eliminate the strong RF feedback. If your PCB does have the pads for C25, you can solder a 104 under R18. Thanks to JE1RAV who reported this issue.

The INdian possibleseller of Raduino VFOs .My email playing up? ... last attempt may have worked It had a false emailaddress.? it's .COM? .last msg if sent likely had .CO? ie clipped during a cut and paste.
PS?
I have bought from him it arrived. It worked It was a Freq counter module NOT a vfo.

Hi,
I already installed the C25 on the backside. Anyway I crashed some Arduinos in the past. At the Moment, the trx is running good :)
But I have some Arduinos in spare? ;)

Matt,
There are several Arduino Nano modules available in the market.
Some of them are using relatively smaller LDO regulator IC and it
is not a good idea for our purpose. With the addition of the
Bluetooth module, the LDO will output around 120mA during TX. It
is very hot if you use higher than 12.6V power supply, especially
in summer.
Also, it is critical to avoid RFI, if your antenna is very
nearby. Even QRP power will cause abnormal behavior.
Thanks,
Adam
