| 1 Notes from OsmocomBB tinkerer steve-m, relayed to me (Mother Mychaela) through | |
| 2 Vadim, indicate that: | |
| 3 | |
| 4 * Calypso TSP signals going to Rita xcvr are wired per canon: TSPEN2 for strobe, | |
| 5 TSPACT0 for reset. | |
| 6 | |
| 7 * TSP controls to the PA are also TI-canonical: TSPACT9 for enable, TSPACT3 for | |
| 8 band select. | |
| 9 | |
| 10 * The two antenna switch controls (Tx low band, Tx high band) exactly match TI | |
| 11 Leonardo, specifically the cheapened 2-band version of that canonical | |
| 12 platform: TSPACT1 is Tx high band switch, TSPACT2 is Tx low band switch, both | |
| 13 inverted per canon. | |
| 14 | |
| 15 But here is the part that deviates from canon: Iota TEN is apparently wired to | |
| 16 Calypso TSPEN1 instead of canonical TSPEN0! |
