Re: Low frequency SDR spectrum analyzer

airspy hf discovery is the best thing for HF SDR.

169 Bucks, but worth it.

filters in front of A/D's, poly-phase sampling. very very sensitive radio.

i often use 192khz BW for weak AM and SSB signals.

a great radio that i use with my homemade loop antenna.

SDRAngel is the rx software.
rtl-sdr dongle is the rx hardware.

i/q generator and hp vector sig gen is the tx source.

can link matlab code for anyone who cares.
