Festival of Frequency Measurement Submission

Festival of Frequency Measurement, 1 October 2019, WWV/WWVH at 5 MHz

Data measured and submitted by Jan A. Tarsala, WB6VRN

Measurements made at K6TY, 34.1175, -118.0198, DM04xc

One-wavelength 40 m vertical loop antenna with maximum response at 70 degrees to true North

Kenwood TS-870S receiver with SO-2 TCXO option (all local oscillators and DSP are derived from this one frequency reference) operated in a temperature-stable residential environment

TS-870S mode was CW (i.e. upper sideband), 50 Hz IF bandwidth, 1000 Hz beat note frequency

Baseband audio beat note frequency measured using Fldigi 4.0 running under Mac OS 10.11 with time set using NTP and audio sampling rate corrected in accordance with Fldigi instructions

Two files are uploaded due to a late start: the file K6TY DM04xc 5 MHz.csv covers 1500 to 2400 UTC 1 October 2019 (nine hours), while the file K6TY 34.1175 -118.0198 5 MHz.csv covers 1500 UTC 1 October 2019 to 1500 UTC 2 October 2019 (twenty-four hours).  The initial frequency error and the aging of the SO-2 TCXO are obvious when the data are plotted.
