Back in January 2020 I upgraded the firmware on my RadiaScan-701A geiger counter and filmed it. Then 2020 happened and I forgot about the recordings... until now.
Here's my experience on how to upgrade the firmware and a little test on a new function. Feel free to share, if you know someone who could use the info.
In case you missed the video where I test the geiger counter donated by RadiaScan, it is here: https://youtu.be/T1HZ8NAXu64
Next public video will be released Friday, January 29th and focus on laser classes. Are you familiar with class 2M and 3R? I'm not sure all manufacturers are...
