To configure the software to operate FSK with HRD’s DM780 (V6.0).
While the configuration / program option window is open, select "Modes +IDs"
and select “RTTY” tab.
In the example shown below the PTT / CW / FSK port is on COM2. Windows will most likely have
assigned your ports differently.
You should enable and select the port that Windows has assigned to PTT / CW / FSK on your PC.
Then select t
he signal line “TX” (this will be used for switching the FSK signal – HRD will automatically
activate the RTS line to provide the needed PTT when operating FSK).
You then need to select “PTT” and disable the “PTT” line as this will cause a conflict in HRD.
Disable the serial comport PTT and select “None” – or via soundcard.
Note that when you have finished using FSK you should re-enable the PTT.
It is important that you close and restart the software (DM780) to close all ports that HRD has been
previously using before using the new settings.
