Fox-1E is now slated to carry a Mode J (2 meters up, 70 cm down) linear transponder into orbit, with a 30 kHz bandwidth and a beacon sending telemetry in BPSK. The goal is to test a design for including linear transponders in future cubesats, most of which are currently limited to single-channel FM receivers and transmitters. AMSAT says there is a chance that Fox-1E will have a launch opportunity next year, but could not disclose details.
