Thanks for the clarification Jerry,
I'm looking forward to Fox-1a and 1b, obviously hope they'll be manifested on flights ASAP but understand that will depend on the evolving free launch opportunities within the NASA ELaNa program.

The Fox-1 series will support High Speed (up to 9600) downlink. For the
Fox-1 we're launching next year, that means that the images from the
Virginia Tech camera experiment will be downlinked on the high speed
because of their size, and the high speed will also include the same
telemetry that the Slow Speed telemetry (sub-audible data under
transponder operations) conveys.
The High Speed mode must be commanded and will be activated by the AMSAT
Operations Team for periods up to 24 hours. Normally the satellite will
run in the transponder/Slow Speed data mode.
The High Speed mode was designed to be experimental, and the Virginia
Tech camera will take advantage of it.
The plan is for Fox-1 Series satellites to be able to support our
partner's experiments which may require high speed telemetry or data
downlink, and in such future cases if the experiment requires high speed
all of the time then when the experiment has completed its mission we
would turn the satellite back to transponder/slow speed telemetry.
