Annular Solar Eclipse 2023: recordings of the entire medium-wave AM broadcast band from Victoria, BC, Canada, Part 3

recorded by Nick Hall-Patch, VE7DXR Grid square of location recorded: CN88ik Maximum obscuration of the sun was 79% at 1620UT on 14 October 2023. These data files are recordings of the entire medium wave broadcast band (535-1705kHz) made during the annular solar eclipse of 14 October 2024 from 1618UT to 1715UT from Victoria, BC, Canada. Data Quality: local noise around 1675kHz and drifting during eclipse. Also. There was a 30 second dropout at 16:20UT IQ data files are .wav format, but the archived files are .zip, with about ten .wav files packaged together in each .zip file, using the prefix " VE7DXR-Victoria-LargeLoop-wideband_220_2020kHz_ ". These files are a supplement to those saved in "Annular Solar Eclipse 2023: recordings of the entire medium-wave AM broadcast band from Victoria, BC, Canada, Part 1” and “Annular Solar Eclipse 2023: recordings of the entire medium-wave AM broadcast band from Victoria, BC, Canada, Part 2”. The recordings not included here or in Parts 1 or 2 are available to provide reference data for the eclipse recordings. Please contact HamSCI at [e-mail] if you require this data. Please see "Annular Solar Eclipse 2023: recordings of the entire medium-wave AM broadcast band from Victoria, BC, Canada, Part 1” for software and for general supporting documentation. The Carrier Sleuth software stored in that location can be used to view .fft files zipped in “VE7DXRVictoria-NFlagAsLoop-CarrierSleuth-Oct14.zip” which will provide waterfall visualizations of all carriers for each AM broadcast band channel during the recording period of these supplementary IQ files. Antenna: North facing Flag antenna, 5m H x 11m L, lower wire 1.4m above ground, with minimized termination to simulate a bidirectional loop antenna; Wellbrook FLG-100LN amplifier Receiver: RFSpace CloudSDR, with 13dB front end attenuation. IQ files with a center frequency of 1100kHz, with 1800kHz wide passband, were recorded using SpectraVue v3.39 software. The CloudSDR was locked to 10MHz provided by a Trimble Thunderbolt GPS Disciplined Clock. Computer time accuracy was determined by Windows NTP server.本数据集由VE7DXR的Nick Hall-Patch录制。 记录地点的网格坐标（Grid square）：CN88ik 2023年10月14日世界时1620分时，太阳最大遮挡率达79%。 本数据集包含2024年10月14日日环食期间，于加拿大不列颠哥伦比亚省维多利亚市，从世界时1618分至1715分录制的全中波广播频段（535-1705kHz）录音数据。 数据质量：1675kHz附近存在本地噪声，日食期间信号存在漂移现象；此外，世界时16:20时出现一段30秒的数据中断。 IQ数据文件采用.wav格式，归档文件为.zip格式，每个.zip压缩包内包含约10个.wav文件，文件名前缀为" VE7DXR-Victoria-LargeLoop-wideband_220_2020kHz_ "。本数据集为《2023年日环食：加拿大不列颠哥伦比亚省维多利亚市全中波调幅广播频段录音 第1部分》与《2023年日环食：加拿大不列颠哥伦比亚省维多利亚市全中波调幅广播频段录音 第2部分》的补充数据集。 未收录于本数据集及第1、2部分的录音数据可作为日食录音的参考数据，若需获取此类数据，请发送邮件至[e-mail]联系HamSCI团队。 请查阅《2023年日环食：加拿大不列颠哥伦比亚省维多利亚市全中波调幅广播频段录音 第1部分》获取相关软件及通用支持文档。该文档存储位置中的Carrier Sleuth（载波追踪软件）可用于查看"VE7DXRVictoria-NFlagAsLoop-CarrierSleuth-Oct14.zip"内压缩的.fft文件，该文件可生成本次补充IQ文件录制时段内，所有调幅广播频段信道的载波瀑布图可视化结果。 天线：朝北的Flag天线（Flag antenna），尺寸为5米（高）×11米（长），下线距地面1.4米，通过最小化终端匹配以模拟双向环形天线；配套Wellbrook FLG-100LN放大器。 接收机：采用RFSpace CloudSDR接收机，搭载13dB前端衰减器。使用SpectraVue v3.39软件录制中心频率为1100kHz、通带宽度为1800kHz的IQ数据文件。CloudSDR由Trimble Thunderbolt GPS驯服时钟提供的10MHz信号实现时钟同步。计算机时间精度由Windows网络时间协议（NTP）服务器校准。
