microFSK
microFSK is a program on a microprocessor installed in the Pro3, it is provided as and additional way
to run FSK. It provides far more capabilities than the simple “bit-bang” programming method used by
most software to produce FSK and we provide a simple program so that it can be used.
It is simple to incorporate microFSK into any DATA mode software and HRD are incorporating it into
DM780. One simply sends the raw text to be sent and the built in microprocessor generates all the
timings and signals required.
Programming info for microFSK can be found here .
Our microFSK interface is provided on the first port provided by the interface the same one as used
for PTT. You will need to download and install the microFSK software, or use software that supports
microFSK. Our microFSK program runs at the same time as your normal DATA software, and can be
arranged to “sit on top” of your normal DATA software. microFSK provides the means of transmitting
true FSK via the microFSK interface, alongside your normal DATA mode software doing the RX as
normal. Your DATA mode software should be set to RTTY at the correct baudrate etc to match the
settings you select for microFSK and it is now only used to decode the RTTY being received.
Using the microFSK interface and software allows transmission of true FSK at ANY baudrate (10-600
baud) and full control over the normal FSK parameters.
The microFSK.exe software is a Windows program that enables communication with the microFSK
module fitted into your interface. It allows you to configure all the parameters that can be configured
in the interface.
Parameters include;

Along with the “standard” baudrates above, the user can specify ANY baudrate between 10 – 600
baud and the mFSK module will generate the appropriate timing for the signals.
