NB ^^^^^ This is one aspect of the Op system that's missing ..a data server to handle the results , if anyone wants to put something together ..be most welcome !, the data from Opera can also be combined with the ROS data mode decodes , giving quite a volume to work with ..... As to what would be useful feature's .... where would one ask ?? 73 -G.. -------------------------------------------------- From: "ALAN MELIA" Sent: Friday, March 09, 2012 3:12 PM To: Subject: Re: LF: Big solar flare - major geomagnetic storms to follow > Thanks Graham.
