* No device freeze when you try to close app while it's transmitting
* Bypassed 100 .wav files limit by implementing paging functionality
* Removed useless progressbar and implemented page info line instead
Moved the MIC TX RX into the main menu.
Changed scanner color from yellow to green, since it is kind of rounded up into an acceptable functionality.
Also, did a bit of cleanup on the code spacing inside the menues.
Thanks @euquiq for a more common solution to the bug.
Added RX gain control.
Now we have full gain controls!
Merged PTT and Voice activation into one option selector.(allowing RIGHT BUTTON to work with PTT off)
This patch addresses the issue detected in: https://github.com/eried/portapack-mayhem/issues/159
This patch will revert the behavior of the function to_string_short_freq
into using spaces on the left of the integer part of the frequency (as it did originally).
When upgrading the scanner app, I did change the behavior of this function eliminating those spaces, so I could gain some characters-worth of space inside the scanner, but I failed to detect that it introduced some lack of padding on the rx->audio app.
Now, it is back as before, and I also did update the scanner so it can cope with the "extra spaces" this function now adds (again).
A bug that enabling audio RX resets the TX gain (perhaps because that changing to receiving mode modifies some registers) inspired me to add this gain control.
Commented out some steps which don't require for the VU meter to work again.
Moved some widgets for gain control.
Added CRC calculation for Vaisala radiosondes.
Added a Checkbox on APP for turning ON / OFF CRC. When CRC on, malformed packets are ignored.
Connected existing CRC function for METEOMAN sondes, using the same "CRC" checkbox logic.
Added the Vaisala RS41 data packet decoding.
Changed the default freq from 402.0 to 402.7 Mhz, since it is more popular freq.
Lowered the frequency stepping, so it is easier to fine-tune the exact freq center, if needed.
Sonde's Serial ID is passed into the VIEW MAP, so now the sonde is labelled on the map.
