Gus, We're not going to see another satellite with a 144 MHz yagi. The "Mode B HEO" ship has long since sailed unless someone can come up with the $15-$20 million or more to finish and launch Phase 3E. However, given how rapidly technology has advanced, I'm not going to count out a large CubeSat (the specification covers up to 27U) getting us back to HEO some day, but it will definitely be microwave band only.
