Using K3/0-mini in FL to conrol K3 at home QTH in VA. The setup has been working quite well. Friday I made 25 QSOs in CQWPX RTTY contest and every thing worked fine. I turned off the rig. This morning I turned on the K3/0-mini and after a short time I got the audio alarm erroer message. This senario happens several times a month. It seems to be happening oftener recentlhy. Could the cold weather have anything to do with it? The fix is to have someone go to the home station and restart the remote site RCC-1258 using microbit. This is getting frustrating. Any one have any suggestions?
