yes, though it depends on whether a center frequency has been specified.  If so then OP25 remains tuned to the center frequency and if not, it retunes the SDR each time a frequency change is needed.  From what I've seen the slow sample rate (250,000) on the PI causes the changes to be somewhat slow, so I was getting the first word(s) of calls chopped off.  Currently (for the PI) we recommend -S 1000000 and setting the center frequency to zero, or omitting it.  Another user reported getting a crash with this, and a possible workaround for it has just been pushed to the repo....  It should be possible to set the center frequency to zero.  When this is done the trunk-tracking mode should work fine no matter how wide the system is, but it does preclude the use of the log-all-talkgroups-to-disk mode, unfortunately...
