Hi Wolf,

Pleased to have a nice QSO, even if the op this side got a bit confused with some buttons !
Yes, I had plenty of time to build a decent MF station, waiting for a permit

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 ;-) 73,   Wolf DL4YHF    QTH Spenge near Bielefeld, JO42FD Am 28.01.2014 10:37, schrieb Michel Brunel:

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)
