QO-100 Station Build & Test Log

Technical documentation, bench testing notes, SDR upconverter alignment, and microwave assembly for the G0WDA Es'hail-2 satellite ground station.

Phase 3 � Microwave Power & Upconverter Testing

2.4 GHz Uplink Amplification & Filtering

Configuring and bench-testing the 2.4 GHz uplink driver stages. Verifying clean signal generation without spurious emissions, matching output levels into the dual-band patch feed, and verifying power consumption under continuous carrier tests.

Phase 2 � LNB Stability & Downlink Receiver

10 GHz Reception & TCXO Modification

Bench testing modified LNBs for stability on the 10.489 GHz NB transponder. Utilizing a TCXO reference clock to eliminate thermal drift during Narrowband SSB reception. Signal locked and verified using SDR Console.

Phase 1 � Dish Alignment & Mounting

Dish Placement & Grid Location (IO83LT)

Mounting offset parabolic dish with clear line-of-sight elevation toward Es'hail-2 at 25.9 degrees East. Aligning skew and azimuth for optimal transponder noise floor SNR.
