Hi I'm trying to run a GPS simulator on my HackRF. Here's the link to the project: https://github.com/osqzss/gps-sdr-sim The author (and another user) have managed to run this successfully on a HackRF (although he says HackRF has a problem of clock unstability, but it still can be used) He uses a 20dB attenuator at the output (with ANT500) and the signal strength on his Android GPS diagnostics app is about 40. I don't use an attenuator and still my signal strength rarely reaches 30 ! What could be wrong with my HackRF? FYI, I've installed a RF shield and a heatsink (bought from NooElec), but I doubt they have anything to do with TX power.
Thanks Mehdi
