This is a BETA release. I suggest to use another SD card to have a working 0.28.0 in case of some problems.
Also - I'm not sure about correct migration of parameters. In case of some problems you can delete params.db from the DATA partition of SD card.
General:
- Most of the bottom buttons with 2 state related controls (on/off) changes state of control with a single press (no need to press and turn VOL/MFK)
- Memory pages moved from GEN button pages to V/M button to make shorter cycle of pages "attached" to GEN button
- RX filters (low, high, bandwidth) moved from GEN pages to DFL
- Added semi-auto notch filter. It tries to find strong constant tone within IQ samples and just move DNF frequency to detected. If nothing detected - it moves DNF center to 3000 Hz. It also might tries to reject some strong tones from the operator voice especially, when remote station frequency response has a peak. Hope, it might be useful in some situations.
- Speaker/phones control moved to the settings app
- Reduced spectral leakage on spectrum and waterfall (see pics below). Now strong signals doesn't spread across the spectrum/waterfall.
- Added interpolation to waterfall - more smooth picture on high zooming.
- Add external USB keyboard hot plug support, fix upper case issue (for example - when typing WiFi password with capital a case)
- Set WF/spectrum range to 48db, when using auto min/max.
- Wifi/SSH keys saved on the SD card (no need to retype after update). This feature was not tested enough. New firmware should be installed for saving - so it will not restore settings for the first time.
- DATA (params, recordings, etc) restored after flashing new version. This feature also was not tested enough. This feature should restore your DATA right after first boot (if you will use same SD card as for previous version). Anyway - it's better to create a backup of your DATA partition before updating, at least for the first few times.
FT8:
- Added RX frequency cursor (green) - indicates frequency of remote station.
- Added TX cursor acceleration, Tx cursor is red now.
- Added Hold TX freq option - when disabled, you TX frequency will follow calling station frequency.
- TX might be started in a short interval (1.5 sec) after new time slot begin - slightly more time to answer fresh decoded CQ message.
- Better support of the non-standard call signs (with /QRP, for example)
- Added 60M band to qso logger
Misc:
- Improve CW messages generating timings. It was an issue with inconsistent duration of dits, dahs and intervals while playing or sending
- Added labels with current values for sliders in the settings (pics)
- Fix: no tx for playback audio after ATU. Also might fix issue with no voice prompts after ATU. Thanks for @infrat
- CAT changes (still in progress). Added reporting S level, ALC, SWR, etc.
- Updated SWR scan averaging
