I’m trying to PATCH a signal that was recorded as “hex” encoding to a much simpler “cq” encoded signal that I recorded myself. It fails to change the encoding to “cq”, and then the data isn’t replaced but seems to be prepended somehow? It returns:

“encoding”:“hex”,“data”:“1011001001011001001001001011011001011011011011001001011001011011011011011EFFE00000000FFFC…”
