Same here, its the damn overflow of contact messages we receive. I wish there was a way to turn the damn radio off.

Someone posted a fix for this on the UBI forums. I can't find the post now so can't credit the guy.. but basically this might help;

Edit your contacts.cfg file to change the following entries;

Display Range To Opportunity Radio Contacts=1500;[>0] kilometers
Display Range To Important Radio Contacts=3500 ;[>0] kilometers

These represent the distance you will get contact reports from. 1500 km seems a little extreme to me. I'm not very likely to travel that far.. so I've reduced mine to 500km. (Frankly, 100km might be enough?) I haven't been on patrol for long enough to see if it works but I'm hopeful it will help.

I'm not sure on the difference between Important and Opportunity messages so I've left my Important at 3500km for the moment incase this is the war news, which I like to get and isn't common so wouldn't spam the messages so much.

In your saved games cfg there is a file called SaveData.rmr , all the messages are in there.
I assume when you delete the messages with notepad the loading time is much shorter.
Haven't tried it yet 'cos I'm about to start a new patrol.
