Morse rx cleanings (#2962 )

* fix ui overlap, align with log box * bring back enum inside the class as a simple enum * correctly restore saved setting whatever the modulation was at exit * set squelch / field_squelch / receiver model in one go, add audio/receiver model stop and start
Morse rx further development (#2959 )

Author	SHA1	Message	Date
gullradriel	927e3b11e7	Morse rx cleanings (#2962 ) * fix ui overlap, align with log box * bring back enum inside the class as a simple enum * correctly restore saved setting whatever the modulation was at exit * set squelch / field_squelch / receiver model in one go, add audio/receiver model stop and start	2026-02-04 14:01:29 +01:00

Herbenderbler	c6130c6e8d	Update Map view labels to match marine navigation standards (#2951 ) Replace Alt: with CoG: and Spd: with SoG: in the Map view to better align with standard marine navigation terminology and the AIS Rx screen. - Alt (Altitude) → CoG (Course over Ground) - Spd (Speed) → SoG (Speed over Ground) Rationale: AIS is primarily used for marine navigation where altitude is typically zero (sea level), while Course over Ground is essential navigation information. This change provides consistency with the AIS Rx screen which already displays CoG and SoG.

Herbenderbler	97f2ca42f1	Fix aviation 8.33kHz step size to reduce frequency drift (#2950 ) Update aviation radio step size from 8330 Hz to 8333 Hz in freqman_steps and freqman_steps_short arrays. This better represents the actual 8⅓ kHz (25000/3 Hz) aviation channel spacing and significantly reduces frequency drift during dial tuning. With this fix, stepping 24 times from 123.000 MHz now correctly reaches 123.200 MHz instead of 123.199 MHz.	2026-01-31 19:35:14 +01:00
