Fusion 5.5 is coming, and with it, one of the most interesting features. Armel just presented a video showcasing the upcoming major advancement in his firmware, and it concerns scan speed. Whether in lists or even in the VFO or scan range, the speed seems to be multiplied by 2 or even 3 while still capturing receptions, ideal for scanning Airband, for example. I've attached a video link so you can see for yourself!

I don't know if the translation is available; if so, the "improve" post is the one on the right.

F4HWN Fusion 5.4

Added a progress bar during scanning with a visual indicator of selected channels

Added a Wide/Narrow mode in AM RX

Improved CTCSS for better compatibility with certified radios

Major improvement to channel name editing: you can now use the letters assigned to the radio’s keypad (those who remember T9 on old phones will know what I mean 😄)

Added information in the SYSINF menu (M52): you can now display details such as firmware upload date, battery status (voltage, %, and type — e.g. 1400 mAh), and radio memory usage (Flash/SRAM)

New Spectrum Analyzer interface! Completely redesigned UI — I’ll let you check it out, it’s really nice

After version 5.3, which notably introduced audio profiles for AM as well as a visual indicator during channel RX, this version brings even more solid improvements!

Please install this firmware on K5 (V3) units only and K1.

See you soon 🫶🏼
