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.

Just found it – it is in SpectrumLab – Digimode terminal

''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.
