Smaller radio operators may find it different but the TV people that I have talked to are very happy with the ease of doing it online. Most found that they had been putting all kinds of unnecessary stuff n the PIF and rebuilding it online helped to weed out the junk.
I don't have any clients that have done it thus far but now that the AMC8 rush is over and the ETRS rush is winding down, I am planning getting my clients moving on the OLPIF front.
I am thinking about buying an auto feed scanner to assist my clients.
And about the time that everybody gets gets their PIF upladed, they will probably drop the PIF requirement completely...
