I created a WinRad DLL controlling the softrock v9.0 Si570. It has functions for setting the frequency, calibrate the frequency, controlling the bandpass filter and calculating the LO for the 2m module. <http://home.ict.nl/~fredkrom/pe0fko/ExtIO_Si570/ <http://home.ict.nl/%7Efredkrom/pe0fko/ExtIO_Si570/>>
