SDR moonbounce signals at 1297MHz

This dataset contains recordings of a moon-bounce experiment performed on 2021-12-16 with the Dwingeloo Radio Telescope (operating under call sign PI9CAM). UHF signals were transmitted with the telescope, and their Moon echo was received about 2.5 seconds later.

The signals were transmitted and received with an Ettus USRP B210. The data was converted to SigMF format. The metadata contains information on the device used to transmit and receive the signals, and about the modulation used. Signals were transmitted with a 210kHz offset.

Apart from the recordings (filenames starting with 'camras-txrx'), which contain both the uplink and the downlink, also the original IQ files that were transmitted are included. The key 'camras:tx_file' in the metadata tells which file was transmitted.

The absolute timestamps are not very well calibrated: the computer doing the recording was not synchronized. The timestamp in the filename represents the creation time of the file, the time in the metadata refers to the time of the first sample as reported by GnuRadio.
