I can’t quite figure out why the bit-error rate of the terrestrial signal from a XM repeater seems to float in and out of tolerance; most of the time, it is right around 3, but it has short bursts up to 25—what’s annoying is that anything over 10 makes it lose signal. (It also only seems to produce a usable signal if I put the antenna within a 10 square-inch area of my office.)
Maybe next year (if I return) I should request a south-facing office.
