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.
