-## SDR-PICO V1 and V2
-
-[A project from Burkhard Kainka, DK7JD ](https://www.elektronik-labor.de/Raspberry/Pico38.html)
-
-The Raspberry Pi Pico can generate an HF (high-frequency) signal on its GPIO pins thanks to its dedicated GPIO assembly language, known as PIO (Programmable I/O).

-## Configuration in putty (115200 bauds)
-
-It is now necessary to access the configuration menu. 
-To do this, hold down the push button “bp menu” while connecting the USB connector to the Raspberry Pi Pico Zero. 
-At this point, a serial communication port such as COMx should appear on Windows, or /dev/ttyACM0 on Linux.
-
-
-```console
->help
-Available commands
-Set transmission frequency                  : freq 7040100
-Set offset value                            : offset -200
-Set callsign                                : call F4XYZ
-Set locator                                 : loc JN07
-Set mode  wspr rtty ft8 hell cw             : mode wspr
-Set modulo in minutes                       : minute 10

-The minimum setup for a quick WSPR test is:
-
-```console
-
->raz             Initialize parameters
->freq 7040100    Set transmission frequency
->call F4XYZ      Enter callsign
->loc JN07        Enter locator
->mode wspr       Select transmission mode
->minute 2        Transmit every two minutes
->dbm 10          Set power level information for WSPR
->save            Save configuration
->show            Display configuration
-
