Hi, Thank you everyone, very valuable advice in this thread! I will not ignore it.
Helmut, the USRP B20x variants are my main target, so be sure I'll be testing with them, it's just not a priority now. Let me explain why the RTL-SDR: lots of folks have this cheap dongle, and it's a very good introduction into this world. It also imposes severe limitations on my code, which is quite painful. Glen, I have a dumb question: your data on 2.4 GHz contradicts some of the models I use. What kind of foliage do you have? Metal buildings? If you have any statistical data, I will gladly add the model to qradiopredict. 73, Adrian YO8RZZ On 9/19/17, glen english <g...@cortexrf.com.au> wrote: > As long as you look after an overload or an intermodulation condition, I > don't see a problem with the RTL-SDR.
