If anyone receives the automated message from my reception of their signal and wonders about the fact that my CPU is reported as being 100%, it's because I have a program called Prime95 running in the background that is looking for mersenne primes and it uses any spare CPU resource that other programs are not using at that time.
DM780 seems to only monitor its own use of the CPU, but I did notice that ROS seems to monitor the system use of the CPU, which will include anything else that is running at the same time, of course. Dave (G0DJA)
