Recording 2 I/Q streams

Post by SDRnerd » Sat Aug 17, 2019 6:26 am

Does anyone know if both the I/Q streams of the RSPduo with SDRuno can be recorded to a internal HD simultanious? A 2 MHz sample rate will be used for both receivers.

I like to make recordings for comparing antennas at night on MW.

An external USB 3.0 drive will also be fine but I guess the ports from the pc will be swamped with to much data.

No issues on my end doing that but my recordings are going to a 2nd internal HD

Thanks Mike! I also use a second HD for this. I do not like to record I/Q files on a HD with the W10 OS mounted.
I'm using a Intel NUC8i5BEH with a Samsung 970 evo 500 Gb SSD and a WD 2Tb 2.5" HD.

Want to make a Mediumwave I/Q recording with a Beverage with Tuner 1 and an experimental Lira antenna with Tuner 2.
The Lira is still in test and should outperform the Beverage in theory :-)

See ya,
Ron

No problem, My main drive is an SSD. I try to keep anything that writes constant data to it at a minimum if possible.
