This image, made with the MacOS DataGraph program by Paul Williamson KB5MU, shows that the Opulent Voice transmit first in first out buffer (FIFO) wasn’t properly reset at the start of the program. This means that there was data already in the transmit FIFO at startup. This is not desirable because when we want to transmit, we want to start with the data that we’re sending. Whether this is voice, or keyboard, or a file transfer, we don’t want extra data at the beginning of the transmission. For voice, this might just mean a very short burst of noise. But, for a text message or data file, it could cause corruption. Visualizations like this help make our designs better, because they reveal what’s truly going on with the flow of data through the system.
