I have noticed something over time and it seams to occur more often. Sometimes when I enter a JA contact call sign either into QRZ, my log, a cluster etc, FlDigi, HRD you name it, there is a notice that the call is not recognized. It happens a certain percent of the time consistently over the last two years. It's only JA, no other country. I work a ton of JA's as they are close, and it never happens with any other country, Russia, SE Asia , AUS. etc. Has anyone else noticed this, maybe if you don't have a lot of JA's you would not. Just curious. Do they have a different system of call sign reporting that maybe our registry does not pick up ? It's not specific to QRZ by the way, its every data base available. If it's not recognized by one, its not recognized at all, thats what I noticed. It's frustrating because it messes up your log that is for sure. And of course LOTW and eQSL won't accept them, as I wouldn't expect them to, since they go as unregistered.
