ROS-HF 7 MHz ZS Net #ros

Graham
 

Checking the  ROS-HF user levels these days, on psk-map stat's 
Noticed an Interesting thing,

There is  a  7 MHz net , round south africa , but, ZS stations are all using
one of the older ros versions , not sure as to  why,  the latest version , provide's
the the  final  optimization , but each evolution came with  changes to  coding 
and the  modem , as one compliments the  other ..
Thus  coding ,  6-9-0  is not compatible with the new ,

It would be  possible to  monitor , using  web-sdr's ,
