I am extremely new to this and I'm learning by building stuff myself so please let me know if this is too vague and I'll elaborate if I can. I'm sure this is something very simple, but can't figure out how to do it.
I have built radios before and know how to modulate a signal as ASK but now I'm trying to send a simple bitstream from a USB port to a radio's input. My idea was to use a serial program to dump bytes into the radio input signal but all the research I have done indicates using rs232 or UART or something. I have no experience with this and I don't want some protocol sticking parity bits in all over the place. I simply want to be able to send, for example,
00000001000000100000001100000100 at a baudrate of \$2048\$. Can I go further and actually send individual bits like start/stop bits?
My intention is to monitor the frequency with an sdr and then learn how to demodulate the bits from the IQ data.
Is there a simple method outputting bytes directly onto the wire or something I don't know about which will prevent me?
Any help or direction would be greatly appreciated.
