* fix for #765, manual mode has unlimited range now
* speedup for button_add.on_select (roughly x70 times faster)
* fix for random freezes while switching to Audio
In scanner app, the bandwidth and sampling rate for AM modulation was incorrect. This resulted in high pitched and distorted sound. I have now copied the settings from the Audio receiver app, and now the sound in Scanner sounds good also in AM mode.

I choose what I think are the best Titles based on existing titles/class names and so on. There were also inconsistencies between TX and Transmit and RX and receive. I renamed them to shorter version TX and RX also added it as suffix where possible to make it clearer in what mode you are in. If you have any other title suggestions or changes please use Add comment on Files Changed Screen so I can change it.
Add Gain control to the GPS Sim App .
(we are clonning the two previous PR's n #395 and #446 of the Replay App, correcting TX Gain control to this GPS Sim App )
PR to increase the BW Options in the Capture App , beyond the current max, 500khz. (from 600Khz till 2,75Mhz) all of them work well into the screen, but only <= 600Khz BW are correctly saved into SD Card with full captured data. (Onwards, >600Khz optiions, at the moment , the created SD card file has decimated data, due - to SD Card writting speed limitations),- but I feel still quite interesting feature to keep them.
Current Replay App , shows in the user menu a UI to select two kind of controls for the RF output level :
1-) LNA GAIN (0..40 ) dB => but it has no TX effect because it is the RX-LNA . GAIN
2-) RF AMP (0 / +14dBm , (that was correct , we have two IC's , RX / TX ) (sw is controlling weill .
Note, although SW Version 1.40 do not leave to control drictly the GAIN TX
, that Replay App , in fact, it was using the inheritated selected GAIN TX from any previous usage of MIC App.
That Pull request alllows now to have the following controls
1-) GAIN TX (0..47 ) dB (now it is OK
2-) RF AMP (0 / +14dBm , (that was correct , we have two IC's , RX / TX ) (sw is controlling weill .
Remakrs : After the change , now we can control the GAIN TX , but not "in the fly" . When we are in the Replay loop , any change of the FREQUENCY or GAIN TX will be ignored , till we play STOP / START the loop again. (but the AMP RF (0 /+14 dBs) it works in the loop withouth any problems (same as before ) .
checking if the ICAO address of the frame and the current item
in the details view match. Slight refactor by placing the decimal
to string conversion function into the string_format module.
Added fix in the scope of issue #365
FrequencyStepView field in TransmitterView class
FrequencyStepView field in TransmitterView class
Update ui_transmitter.hpp
Update credits
Fixed left padding of the decimal part of the numbers.
features a square wave mode.
Added proportional beep duration based on the RSSI as well.
Now reading the current radiosonde frequency from the
battery backed RAM instead starting with the same frequency
all the time.
I think the Jammer deserves a green icon, since it actually does it job pretty well.
Then there is a Jitter parameter. It allows to introduce a jitter from 1/60th of a second up to 60/60th of a second (a full one). It will delay / move forward either the TX or the cooldown period for a maximum of a half of the time you choose as jitter.
Meaning: If I choose 60/60th, a full second of jitter, it will produce a random number from 1 to 60.
Then it will calculate jitter = 30 - randomnumber
THen it will "add" that (positive or negative) time to the time counter for the next jitter change of state.
Discord User jteich did some investigation (Thanks!) and helped me understanding this rather obscure parameter:
Internally, is called "TRIGGER", and is passed into the baseband when configuring the desired spectrum sample rate.
Please forgive me in advance if this explanation is not 100% correct. It's only my interpretation, based on my own observation and jteich's comments over Discord chat.
This trigger parameter apparently determines the amount of data over time used for calculating the signal's power inside each specttrum's bin, before considering it "done".
In short, if you lower this resolution value then the cascade will tend to be rendered a bit faster, while kind of blind to tiny signals.
On the other hand, a bigger value will help rendering and distinguishing different signals on the cascade.
Too big a value can easily clutter up the cascade. But then it may be a "blessing" when inspecting higher freuqencies -where hackrf is more deaf"
The default value of 32 is quite decent. But then, now you can experiment with it. Cheers
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.
- Now we have variable CLKOUT.
- CLKOUT can be set between 10kHz and 60MHz.
(The output signal will become mostly sine shape when reaching 50MHz.)
- Click on freq setting field to change tuning step.
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.
Values where left bit-shifted upon being entered by the user, so resulting SSID being transmitted was a different number. This shifting was happening both on Source and Destination SSID values.
* 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
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.
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.
