How fast can the tuner change frequencies? This will impact its ability to scan.
Can the same USB receiver function simultaneously as the signal and control receiver? If not then the HW cost is $19*2.
- FiloSottile 13y agoYeah, it is said at the end of the article that the system is suboptimal because the receiver will have to switch back and forth between signal and control.
- coin 13y agoWonder if it's possible to use two receivers, given that are so inexpensive ($19).
- Maxious 13y agoIt does function simultaneously by switching away from the control channel. More advanced software like SDR-Studio or GNU Radio can extract multiple channels/signals.
- superkuh 13y agoAccording to my tests (with many dongles of E4K and R820T tuners) it takes about ~50 milliseconds for everything to happen. Use keenerd's experimental branch for fast tuning with R820T tuners. I'm not sure the main branch has fixed the driver yet. My best guess is that something in libusb is slowing down the process which in theory should only take ~8 milliseconds.
