Terry,
could you decode PSK8?
I switched back to
PSK31.
On my control receiver es was hart to decode PSK8.
Will do some
more tests.

''sounds good''.
This is the INVISIBLE ROS that spooked MAL
hihi
If you can here
mf-2 , then the power is too high .
Gerhard dk6ni uses this mode , you might have
qso
could be the first
data qso on the new band ?
I don't see any
signal on the web-sdr , looking at 475 , small
trace hf , but what software has psk8
?

Graham,

That's a
good Tx system ! much smaller than
my Racal MA1723
If you have
SDR then the ros-mf data modes can
be used directly with SDR , very little
use has been made of them due to the need for
audio>rf or sdr Tx drive ..or
by using Transverter
These modes
are 100 Hz B/W MFSK , MF-2
is the same s/n as wspr and MF-7 ,
the same data rate as psk32 , but some
10 to 12 dB lower s/n ...part of the ROS data
package , download the same site as opera
This was
nearly a mistake as Joe has the Rx set
to 7 only , so when I switched to MF-1 ,
decodes stopped , the MF-7 was a warm-up
test !
Good luck with
the trials

Graham,
I am using a Soft Rock SDR transceiver.
I
modified a Soft Rock SDR 160m to 500kHz.
Additionally I am using a
CB PA changed to 500kHz with 80 W output. Ok, this is not very
linear.
That's means any modulation mode is possible. Why are you
asking?

Do you have

BSK31
hello MW,
I am transmitting PSK31 on the
transmitting frequency 475kHZ (not dial).
It's mainly a test. It's
the first PSK31 transmission with this equipment.
