  1. When he says that the symbol rate is 1766, does anybody know what that refers to? The "shorts" (10) and "longs" (1000) have different durations. Or does it mean literal bits per second, like a "long" would be four "symbols?" Sorry, both programming and radio are very out of my wheelhouse and I'm trying to port this over to a cheap $0.50 433 mhz module I've got attached to a microcontroller running circuitpython. I've got everything pretty much working, but I need to know the duration of the pulses so I don't spend hours trying different pin values and troubleshooting, only to learn I've accidentally doubled or halved the symbol rate. Right now, I believe a "short" should have a duration of 566 microseconds, and a "long" 1968 microseconds. The preamble begins with a pulse of duration 9056 us, followed by a silence of 4528 us. Can anyone confirm or deny this? It looks like there used to be a photo on the post with this information but the hosted image has expired.
