I managed to transmit FM radio, finally. Here's whta I really need:
I have a file, arbitrary length, of 16 bit signed integers . This is assumed sampled at 20MHz, that is, bandwidth 0 to 10MHz. I could make it a mono wave file, but no header is easier. I want to read it into grc and change it (presumably by multiplying by a complex sine wave) to a stream of complex numbers sampled at 10 MHz, presumably from -5 to 5 MHz. This then gets fed to an Osmocom sink to HArckRF which transmits it centered on some high frequency. The only thing I don't know how to do is read in a plain (non-wav) file at 10 MHZ and get it to a complex stream at half the sample rate centered at zero. How do I do these two things? _______________________________________________ HackRF-dev mailing list [email protected] https://pairlist9.pair.net/mailman/listinfo/hackrf-dev
