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.
