Hi Dylan - From what you've posted, it sounds like you have an issue with the HackRF One, not the NI USRP; could be configuring it, or some runtime issue; really not clear. Given that this is the -USRP- users list, I'd advise you to look to GSG about what's going on; this website provides some good options for someone looking for such help: < https://greatscottgadgets.com/hackrf/ >. Hope this is useful! - MLD
