Ok Roland
You need ROS
7-1-1 from the same site as Opera
Install is the
same , create a folder and un-zip into
- run the install exe
user info etc
as normal
To access the MF
modes select LF and MF bands from the
frequency list , these are all dial
frequency , usb
if you send
beacon , then you should have ''de''
before the call , or the software will
not recognise your call
for MF-2 , de
g0nbd would be long enough , software is
linked to the psk-map as well
to decode , the
Rx station 'must' decode the start of the signal ,
as the sequence is LOCK-DATA-STOP
so to ensure correct
RX - TX alignment , the protocol is to use
the 'dial - usb' frequency as operating frequency
, same as Opera ,
If you have any
problems email Jose direct or myself , but
the mode is quite stable now .. there
are a lot of features in the ROS data mode ,
with e-mail reports , remote operation
etc ,

Graham,
I'm using Spectrum Lab.
How do I find
the program for mf.-2? Is it ROS v7?

''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.

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.
