Nick,

Could you confirm that switching TX frequency takes "a few ms"? How did you get this number? Is it the same for switching TX frequency after the code has been running for a while, that is, reconfiguring the TX frequency dynamically?

Every time you tune the TX you'll have to wait a few ms for it to become
stable. For voice transmission purposes, a few ms is effectively
instantaneous anyway. And if you aren't retuning, then it will come up
instantly, because the LO will still be running in between sample
bursts.
