[Hackrf-dev] HackRF DX 100Km on 1296.1

[Tom]

Nice work, I’ll have to check mine at 433mhz to see if I get a signal so close to the primary.

Thanks, Tom, for posting the TX code!  I tried it with the output from the hackrf going to my spectrum analyser to see how clean the output is.  Attached are three pictures:

2569 - tuned to 144.3mhz
2575 - tuned to 432.2mhz

2579 - tuned to 3456.2mhz

At 144.3mhz there are some other signals, but nothing a good bandpass filter shouldn't be able to clean up.

At 432.2mhz there is another strong signal, very close in.

At 3456mhz there are many other signals as strong as the primary signal.

Glen, kc0iyt
