Ok Michel,
thanks, and you're not alone .. also a bit of confusion with the
buttons here, and as usual I didn't look into the manual about the
pink colour of the 'free msg' field (where I entered the final
message, maybe it contained too many bits for transmission and
didn't get through).
For Andy 'CNI: Here is a comparison with Michel copied from WSPR,
just received here some minutes ago. Difference about 15 dB.. but
chances not too bad for an aural CW QSO later in the evening:
1738 -3 0.6 0.475654 0 F5WK JN18 27
1742 -18 -1.0 0.475632 0 F6CNI JN19 13
1742 -25 -0.6 0.475792 0 IW4DXW JN64 40
1744 -14 -0.1 0.475654 0 F5WK JN18 27
1748 -20 -2.0 0.475632 0 F6CNI JN19 13
1748 -20 -1.1 0.475660 0 I5EFO JN53 30
1748 -17 -0.6 0.475792 0 IW4DXW JN64 40
1750 -12 0.0 0.475654 0 F5WK JN18 27
Michel's signal at -3dB was audible here already.
But as usual, the QSB is extreme (F5WK: between -3 and -14 dB
within a few minutes).
73,
Wolf .

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
;-)

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)
