Hi,all.
 
To date , not tried a multi tone data sys= tem .=20
 
The Olivia system , would seem to  p= rint=20 well into  the noise ..may out perform  psk31
 
The 'multipsk' software has a 250 x 8 ton= e=20 setting  250 hz/bw  8 tone freq , I shall set the 'purple' cente= r=20 freq marker , to  503.3  dead (+/- few c/s) . the output spectru= m=20 looks quite clean , and should not spread .
 
There are wider versions , but 250 =20= should=20 be 'ok' --- If anyone is xtal fixed , plse let me know and i can qsy=20
 
>>>> Sorry to  those who= 'know'=20 , follows  notes on reception <<<<<<
 
As its possible , from observation at 'HF= ' =20 olivia will print from below the noise level , accuate rx seting may be ne= ede=20 , 
 
rx settings 'usb'   - dial freq= uency=20 to  give recovered audio center frequency to  that of the=20 transmission and software settings 
 
i.e.  The tx settings will be =20= -dial=20 frequency - 502.000 Khz ,  mode usb .. software tx/rx tone , center=20 frequency,  1,300 Hz , giving 503.3 'carrier'
 
The reverse applies for 'rx' dial  5= 02 , usb=20 ,  software , -purple mark- 1300 Hz
 
 using a narrow filter should not be= needed=20 as the soundcard/software will provide the slectivity, also narrow filteri= ng=20 may 'round' the pulses and reduce the s/n at the rx .
 
 
 
NB .. The new 'digital master 780' also s= upports=20 the mode, but dosent appeare to  support the '250x8'  narrow ver= sion=20 .. other packages may do.
