I'm wanting to get into some of the RF world, I have a NooElec R820T SDR and a Baofeng UV-5RAX+ (w/my technical license). I'm looking at the HackRF and the YARDstick, can the HackRF do (almost) everything the YARDstick can? If the HackRF encompasses the YARDstick's frequency ranges, should I just get the HackRF or is there some things you can't do with the HackRF that you can do with the YARDstick?
