Fixed compile error: Use new variable "_current_offset" instead of old "_settings.Offset"

The size of the picture box is reduced due to layout changes. To make the third bandplan line visible again the "height" of the  bandplan is changed from 255 to 246.

Flickering of callsign in BATC spectrum fixed.

Spectrum display did not scale to PictureBox size. All hard coded 255 "height" values exchanged with "height" variable which contains the real size of the Picturebox. Actual 246.

Changed to use real fft_strength value.

be compatible with QO-100 wideband spectrum code at website.

code added to calculate and show the dBb values.

uses BATCSpectrum.height for correct calculation.

Draw a white signal rectangle and print dBb value if mouse is moved over a signal.

Display of channel info fixed.

Display of channel info fixed.

Don't tune to BEACON.
check for TX frequency only if in bandplan segment.

Don't tune to BEACON.

Show exception message box.

max_strength added show a line in signal which represents max. allowed strength.
Some small name changes.

Red overpower box changed.
Red overpower line added.
Manual RX symbolrate selection added.

locate SRForm dynamically to BATC spectrum window.

New pluto_control_enabled and quicktune_enabled flags added to avoid actions in spectrum if feature is not available.

New quicktune_enabled flags added to avoid actions in spectrum if quicktune feature is not available.

prepare for tuner based avoid beacon function

Tuner 1 often do not set frequency at startup.
Added a delay and wait for websockets to connect.
Show message after 500mSec delay if the sockets still not connected and wait again

no control box

Spectrum Timer temporarily removed.
Small optimizations.

This reverts commit b4528e7.

BATC Spectrum has actual no dependency with quicktune feature.

show controlbox again.

function linkBatcSpectrumSettings_Click added.

make linkBatcSpectrumSettings visible.

linkBatcSpectrumSettings.Click added.

tuneModeSettings forms added.

bandplan.xml will be copied to the right directory during build process.

bandplan was already under "extra" directory. So use this file and copy it to executable path.

add padding constant to remove useless bytes from data stream.

use more precise start frequency of spectrum.

Use more precise start frequency of spectrum.
Use real fft data size for calculation.

The changes give more precise frequency calculation over the whole spectrum span.

Calculations optimized.

Symbol Rate Form added.
It is used when the right Mouse button is pressed within a tuner field.
This will force a new tuning with selected symbol rate.
Function is as within QO100 WB Live Tune program.

New BATC Spectrum settings forms added.
One option allow to select the layout of the over power indication.
The other options are disabled till auto tune function is working.

merge devel to main

use float in rx_blocks for higher accuracy.

use RectangleF higher accuracy.

750kS symbol rate added.
Several OM's use this symbol rate.
So allow tuning to this rate.

This is not necessary and annoying.
I introduced it some time ago and revert this change now.

better exception handling

prevent exceptions

drawing lock position in code fixed.

If usb ftdi was not found and program was closed an windows exception was thrown.
Closing the usbDeviceCollection and usbContext before leaving the program solve the problem.

on request of an OM I implemented streaming and recording indicator at streaminfo.

This will respect a changed default offset in settings.
