Added a PRESETS.TXT file (inside /LOOKINGGLASS folder).
Also optimized the way the spectrum signal is integrated into the cascade.
Added provision for ranges lower than 240MHz but I am afraid that at this time it will not be advisable to lower ranges any more than 240MHz, since some artifacts and frequency running - moving out of place- occurs.
I can only hope that someone with a better understanding of hackrf's inner code can fix this issue and perhaps enhance the scanning speed.
I found some "original commenting" inside the code:
// TODO: Move more low-level radio control stuff to M4. It'll enable tighter
// synchronization for things like wideband (sweeping) spectrum analysis, and
// protocols that need quick RX/TX turn-around.
Which makes me think that there are things "missing" from the portapack side of the code, for allowing serious speed sweeping. So I am concluding that with current "portapack framework" this might be "the best possible thing".
It is to be noted that the "new" internal sweep mode code is signed by:

Maybe Mike or Dominic can be contacted and hopefully lend a hand on enhancing this code.
Added a nicer MARKER (thanks to XSX(H1) contributor for the suggestion)
Fixed a bug that made the screen scroll from top, when using a popup "window" and returning (like, when pressing the DC VOLTAGE enable / disable" button on top bar) THanks to GregoryFenton for the testing and bug spotting!
Capable of showing a cascade with full bandwidth scan. You can select Min and Max Mhz for the cascade.
You can move a marker so to (aproximately) know a particular frequency on the cascade. If you press the select button, the app will jump into the RX -> AUDIO app, already tuned into the just "marked" frequency.
This first version SURELY has space for lots of optimizations and improvement in general.
* 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.
Also added the fields "DateTime" which just shows the raw timestamp that portapack assigned the last packet received, in the format: YYYYMMDDHHMMSS ... And "Frame" which shows the packet # (or frame) for correlating with other software / verify that there are new packets being received.
Also moved a string function for returning rounded-up decimals, originally inside the whipcalc tool app, into the string_format functions library, because I used that function on TEMP and HUMIDITY values inisde the radiosonde app.
Finally, the whole UI has its widgets moved a bit, giving space for these new parameters.
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.
