This repository contains HamSCI December 2020 Eclipse Festival of Frequency Measurement result from my home station JJ1BDX in Setagaya City, Tokyo, Japan at Grid Locator PM95tp.
9-DEC-2020 0000UTC - 16-DEC-2020 2359UTC
- Antenna: 2.2m-length 30m-band whip at 8m height above the ground
- SDR frontend: Airspy HF+ Discovery, without GPSDO
- SDR software: airspy-fmradion 20201204-0
- Recorded 8kHz-rate WAV files at approx. 9999kHz USB
- Airspy HF+ Discovery offset: 1.1311 Hz higher (i.e., 10MHz was mapped to 998.8689Hz), measured by Leo Bodnar mini GPSDO
- Estimated frequency of received AM carrier for the standard frequency stations (BPM, WWVH, WWV were observable)
- Estimated signal strength (by airspy-fmradion dBFS IF strength reading)
- GPSDO offset measured after the frequency measurement on 17-DEC-2020
- Raw data set is available at the designated Dropbox folder
- aggregated-values/: merged data of from the measured-values/ directory files, and the calculation/estimation/visualization R code
- gpsdo-values/: GPSDO-based calibration data
- graphs/: summary graphs by date
- measured-values/: measured data by analyzing the WAV files
- measurement-code/: the WAV file analysis code in csdr and C
- Kristina Collins, KD8OXT
