''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,
sounds good.
Let me have a look at it and then a test.
May be I can do it to morrow.
Today, I am transmitting PSK8.

Ok Roland
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 transvertor ? can
use any audio based mode ?

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.
