Hello Michel,
Thanks for the QSO and the info - your JT9-1 signal was mostly
audible in 2.7 kHz audio bandwidth.
Most of my MF station (especially the RX) is also PIC controlled -
not via DDS but old-fashioned DTMF tones ;-)

Hello
Tobias,
Thanks for the JT9 QSO and the good report.
I've been using 200 watt RF power into a rather inefficient
antenna: 10 meter high, with almost no toploading.
For transmit, I use a "direct link" to the WSJTx software to get
the 65 channel symbols as a lookup table.
Then they are sent to a PIC driving a DDS. Everything is under
the control of the WSJTx software (TX frequency ,PTT, messages)
