Why don't you want a software defined radio?

pautech • Feb 1, 2013 • View on HN

look at HackRF, it may be better, if it gets released

ultrasdr • Jul 28, 2017 • View on HN

could rtl-sdrs and rpitx be used at all?

kweks • Jul 2, 2016 • View on HN

The BladeRF or the upcoming LimeSDR can handle this.

Since we're on HN, how about an RTLSDR, a Pi, and op25?

Why can't we just get a software-defined radio in the hardware...

Can you do this with software defined radios?

HAM Radio or SDR! It's worth picking up something as inexpensive as a Baofeng or RTL2832U transceiver, even just to listen on common frequencies.

Perhaps they could be used with an rtl-sdr device?

Any recommended resources to get started with SDR?
