I'm not ready to give up just yet because I'm going through Michael Ossmann's video lessons and using Pentoo. I haven't been getting satisfactory reception from Windows software even when using a great 20 meter band loop antenna that is 15 feet off the ground. I'm just hoping the Linux setup and software gives better results, however, broadcast radio receptions was poor during the first video tutorial on Pentoo. I have also update the firmware and CPLD from Pentoo. I have not transmitted yet. I'm not a very experienced ham or SDR user so I will have to draw my conclusions once I'm done with all the video lessons. > Todd Harrison > www.ToddFun.com > > > > > On Tue, Oct 28, 2014 at 12:51 PM, Scott Halligan <scott- [email protected]> wrote:Hi, > I am coming to the unfortunate conclusion that I may have a defective HackRF One. I purchased it via NooElec and received it back in August.

I am not using an ANT500; in each case I am comparing using the same software, MSPS, bandwidth, etc along with various external tower mounted antenna both at home and at work (local PD with scanner antenna on tower). Sadly without fail in each case the HackRF One is coming up in last place. The final straw was viewing known signals between 154-156 MHz using SDR# and comparing the HackRF One to the RTL dongle. Signals are louder, stronger, and clearer with the RTL dongle. > I have updated the HackRF One to the latest firmware and CPLD using Pentoo. Both went without a hitch.

Did you ever get any resolution to this? I purchased two HackRF's (Kickstarter and Nooelec) and one has issues (extra noise, reduced sensitivity, lna appears broken). I've sent Mike a number of messages, but he will not respond. This has been going on since I got them in late August. Nooelec sent a couple of messages also, with no response. It would seem that many stores are selling this item, but do not offer any warranty at all, they just refer you back to Mike - who will not respond. Doing more searches now, I can see there are others out there with defective units - after the huge delays in delivery this is beyond frustrating...Does anyone know how to warranty this through Mike?
