1.1 Audio DSP function added
This is an Audio DSP that uses a microphone attached to the STM32F746 board.
It is a function to filter the sound frequency range coming from the radio.
Band Pass Filter (50Hz, 100Hz, 150Hz)
User Filter (Variable Bandwidth)

1.2 The frequency of WSPR has been expanded.
In the 2m band, the Si5351 clock must be stable.Β I recommend using 27Mhz TCXO for wspr on 2m.
You can use any oscillator in any band except 2m.
Videos related to WSPR will be posted soon.
1.3 I have changed the GUI of 'Single Frequency' and 'Tune SWR'
Single Frequency
Tune SWR
1.4Β I changed the GUI of S21-Gain to increase the size of the Auto button.
1.5 Other minor updates
Β -Β Apply default settings to users who are new to WSPR
Β -Β Fixed an issue where fonts would go out of range in the LCR meter.

1.2 The frequency of WSPR has been expanded.
At the request of the tester, 630M, 2190M, 4m, 2m have been added.
Please use WSPR only for added band. (630, 2190, 4, 2)
In the added band, only WSPR works normally.
You can use any oscillator in any band except 2m.
