Once I had the hackrf working in SDR# I tuned into local radio stations as a first test which went great. The reception was surprisingly good and it was able to pull the station name and (depending on station) song title as well which was quite neat.
As a next test I followed the RTL-SDR tutorial on decoding Pocsag (pagers) quite successfully which was rather neat!
I have received a 900MHz and order a 433 MHz antenna to try and improve reception as the onboard antenna is disclaimed as being quite poor.
Will be fun to try transmitting as well at some point but for a reception only situation this seems like a great start.
Total for just the copter bits (no battery) was $16.75, with battery and charger you’re at $23.25, $28.05 with spare battery and props. Pretty cheap for a usable looking quad thats compatible with the 9x transmitter!
If you don’t already have a transmitter a cheap compatible option is the WLtoys V929 V939 V949 Beetle 4-Axis Quadcopter 2.4G Transmitter E728 $14.85. Its the same one pictured above. I don’t know what the quality is like on though it certainly appears to work.
You can also get the V939 bind and fly (so it doesn’t include a controller) pre-built. Its actually quite cheap on its own at ~$30.
