Data:
Data is ordered in 256 byte blocks. Each block is folloed by a checksum cancellation byte.
Last block can be smaller than 256 bytes and is also followed by a checksum byte.
Before and between data areas are a lot of small 'noise' blocks.
They are roughly 70-80 pulses in size and function is unknown.
Checksum:
EOR of all 256 data bytes within a block and the following cancellation byte should be 0x00.
