PROBLEM AT M1ABD-3.
Tonight I noticed that M1ABD-3 was not on the map. A check with www.aprs.fi showed that it had not been transmitting for most of the day. So a trip to Headquarters was made.
I found the computer was turned on but there was a message on the screen saying "Operating system not found"! The computer was re-booted and started up normally after doing a Scan Disk.
So it looks like the HDD could be on the way out.
I have a new computer to install at Headquarters once it has been cleaned up and Uiview installed. Hopefully the old computer will last a while longer.
