Notes from OsmocomBB tinkerer steve-m, relayed to me (Mother Mychaela) through Vadim, indicate that: * Calypso TSP signals going to Rita xcvr are wired per canon: TSPEN2 for strobe, TSPACT0 for reset. * TSP controls to the PA are also TI-canonical: TSPACT9 for enable, TSPACT3 for band select. * The two antenna switch controls (Tx low band, Tx high band) exactly match TI Leonardo, specifically the cheapened 2-band version of that canonical platform: TSPACT1 is Tx high band switch, TSPACT2 is Tx low band switch, both inverted per canon. But here is the part that deviates from canon: Iota TEN is apparently wired to Calypso TSPEN1 instead of canonical TSPEN0!
