DRM Australia 081514 1136utc 1271.2kHz WUSB captured this Friday morning. Note that my habit is to tune in a DRM signal to get the lowest possible Sample Frequency Offset , kinda a DRM signal zero beat in the wide upper sideband mode WUSB. That setting then becomes the DRM frequency readout in the band on the display for the SDR-IQ.
If others have a better method, am very interested in the feedback.
It was a very very tough capturing this DRM Station ID because it was so weak here. Right near my noise level at S5. After several minutes, and adjusting the band pass filter to very tight parameters, finally got the station ID to display. No audio. For a few seconds had a S7 with a single burst of audio. with a 23.54 UEP kbps, I was surprised to get even that.
SDR-IQ band pass filter was set to:
Low Cutoff Frequency: 4000kHz
High Cutoff Frequency: 12600kHz
Over all bandwidth of: 8600kHz
Frankly, I didnt think a DRM station could be partially copied with this narrow a filter. There were signals on the edges of this DRM. Toughest DRM station signal conditions ever for this location to be copied.
Rare signal circumstances for a DRM capture for this South Bend, Indiana receiving station to be sure!
All receptions for this log station description:
SDR-IQ using SpectraVue software and recording 190 kHz rf spectrum to
hard drive for repeated play back and configuration changes as needed to
improve copy intelligibility. Antenna is a Carolina Windom 265 feet long
running North to South with long run on the North end. Location is South
Bend, Indiana one mile South of the Michigan border out in the country.
Amateur radio callsign of WD8ARZ and name is Bill.
