Review of FT-8 on your mobile phone by VK3YE- link - Off Topic - SOTA Reflector
I run FT8CN via a modified Bluetooth speaker making use of the VOX in my FT817. I used it a bit during the 10m challenge in 2024.
I haven’t looked at FT8TW lately, but it is being improved I guess it is worth another visit.
