dongguan-x: Sihuadon R-108 - 2020 vs 2018 versions - Operation behaviors

Bugs and fixes

According to reports from some owners and testers, namely the well known radio enthusiast "todderbert" on YouTube that is also a Amazon seller, at least two operation bad behaviors were found on the 2018 version of the Radiwow R-108 documented by "todderbert" on his videos for the old and new versions:

• Decrease in AM sensitivity when switching between radio bands - Select MW and tune a weak radio station; switch to another band and then return to MW band; the weak station is now noticeably weaker.
  • The workaround fix was to turn the radio Off and On.
  • This firmware bug was fixed on the 2020 version of Sihuadon R-108.

• Popping sound on earphones when pressing some keys - When browsing with the Up / Down buttons and when changing between radio bands a popping noise is heard on earphones.
  • This behavior is not noticiable on the built-in speaker.
  • No workaround except to use presets and staying on the same band when using the earphones.
  • This bug was not fixed on the new 2020 version.

 

Overlooked or hidden features

Some operations are not indicated as primary or secondary functions at the buttons/knobs labels. Depending on the user guide version in use, some operations may be omitted altogether, namely these ones:

• Audio tone - Press and hold key "4" to choose between Music or News audio mode.
• Toggling SW bands - When in SW band, use the key "0" to toggles the shortwave bands.
