What's New in SimpleFT8

0.6.5

August 8, 2026

A more reliable, clearer FT8 station: • Audio meters now use smooth level ballistics, a readable peak hold, and clear clipping feedback. • Fixed CQ-to-QSO handoff so replies and signal reports transmit in the correct next slot. • Made transmit state explicit across iPhone, iPad and Mac. • Added the dial frequency below the waterfall and a quick Hunt/CQ switch. • Distances now use kilometres or miles according to device settings. • Band Hopper is now Mac-only and requires connected CAT/VFO control, stopping safely if CAT disconnects. • Simplified Settings by removing inactive switches.

Litener soon to be sender!

I am using this on a MacBook Air and a SDRplay. My antenna is an indoor dipole. I have decoded hundreds of messages at all hours on both 20 and 40 meters, with farthest away being Qatar (I’m in South Carolina). I am looking forward to upgrading my license so I can send, and the feature set on this package seems to have everything I will want. There are some enhancements I’m looking forward to as well. Most importantly the software has been extremely stable with zero seizures. Thanks JJ!
