Why we dropped recreational radios like Baofeng, Anytone, and Wouxun

Error correction: at the 2:21 mark, the term "open circuit" is used. That should have been, "closed circuit". I define a "recreational" radio as a communication device typically adopted by the public as a means for communication. Usually these radios are inexpensive, and therefore do not carry an IPX rating, or at best, an IPX rating that only pertains to dust and dirt ingress. Most of the radio manufacturers of handheld radios produce a low cost radio that is prone to moisture damage. However, some offer radios more suitable for specialists and professionals such as guides, SAR, etc. 00:00 Analysis of a TYT UV98, a typical recreational grade radio* 01:12 moisture and circuit boards 02:00 example, why you should not carry a recreational radio in a jacket pocket when skiing or it's raining 02:42 charger bases compared with respect to AC/DC inputs 03:30 dangers of AC input charger bases 05:12 AC adapters and safety 06:00 how TYT achieves an IPX rating 08:15 two Anytone and Wouxun radios demonstrated, and why they got water damaged It should be noted that the circuit board used for illustration in this video was not confirmed to have been damaged by moisture. It was bricked during a programming procedure, and the cable was subsequently tested on another radio and confirmed to be operational. One possability with this unit could have been a closed circuit between 2 PCB traces or solder joints when connected to the USB port of the computer causing a surge. (When left unpowered in a humid environment, dust absorbs moisture from the air. Humidity can cause corrosion by itself, but more likely the corrosion will happen at power-up. Within seconds, dendrites form and create a short-circuit.)
