You sure have that right re interference due to
modern digital lifestyle, David. My
always-reliable Casio Pathfinder watch updated
great until I added a Time-Warner converter in my
bedroom a couple of months ago. It updates fine if
the converter is unplugged, not at all if it is
plugged in. OTOH -- other electronics nearby,
including a Roku and old 9" CRT TV, don't impede
the update. So mostly the TW converter is
unplugged and I use the Roku for watching TV in
bed at night.
