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?

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.
