OSCAR-100 transceiver setup

Phase 0
Rx only with SDR and beacon centering for frequency stability using standard Fracarro LNB.

Phase 1 (current phase)
Rx only with SDR and beacon centering for frequency stability using qro.cz LNB with remoted 25MHz TCXO.

Phase 2 (tested but probably 10MHz signal needs filtering)
Rx only with SDR and beacon centering for frequency stability using qro.cz LNB with GPSDO feed at 10MHz to the qro.cz BIAS-T.

UPDATE: Filter needed for 10MHz (not a surprise, but what an improvement)

Phase 3
Rx only with SDR and beacon centering for frequency stability using qro.cz LNB with GPSDO feed at 10MHz to the qro.cz BIAS-T.

Introduction of a mixer and a signal generator to downconvert to 2m frequency.

Phase 4
Rx only with FT-857D/FT-726R and beacon centering for frequency stability using qro.cz LNB with GPSDO feed at 10MHz to the qro.cz BIAS-T. A signal generator will downconvert to 2m frequency.

Phase 5
Rx and Tx using FT-857D/FT-726R and beacon centering for frequency stability using qro.cz LNB with GPSDO feed at 10MHz to the qro.cz BIAS-T. A signal generator will downconvert rx to 2m frequency using separate Rx-Tx Antennas.

Phase 6
Rx and Tx using FT-857D/FT-726R and beacon centering for frequency stability using qro.cz LNB with GPSDO feed at 10MHz to the qro.cz BIAS-T. A signal generator will downconvert rx to 2m frequency using a single Rx-Tx Antenna.
