It's hard-coded.  I just checked and it's on a five minute timer.

Recent Xastir's will do a quick disconnect/connect when they detect
no activity, so you won't end up missing much on the datastream.
Earlier ones did a 50% duty-cycle thing here, where the detect and
disconnect at one check interval, then reconnect at the next.  It's
always good to upgrade and doesn't cost a penny.
