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)

Please refer to LInk below for how to use 'Audio DSP'
http://www.hamskey.com/2019/05/how-to-use-audio-dsp-on-antenna.html





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.


In the 2m band, the Si5351 clock must be stable. 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

1.4 I changed the GUI of S21-Gain to increase the size of the Auto button.


1.5 Other minor updates
  - Apply default settings to users who are new to WSPR
  - Fixed an issue where fonts would go out of range in the LCR meter.

    Hi Ian.
    another "green tail" artifact that I noticed. most likely it does not depend on the firmware version. most likely this is one of the "childhood illness" of the device that has not yet been corrected.

    Where is the "green tail"? In the Smith chart? That's normal. It's not a single frequency but a sweep + -500 kHz.

      But this is a single freq. mode... or is the frequency scanned in this mode?
      Can I set a constant frequency?

      Single Freq mode also scans nearby frequencies (+, - 500Khz).
      It is fixed in the program.
      This is shown in the Smith chart as well as in the small graph at the bottom left.

      and there is no way to make a fixed frequency in this case?

    I confirm this problem. No need to restart, just disconnect and connect the antenna. It is strange.
