I found this
https://github.com/opentrv/OpenTRV-standards/blob/master/standards/protocol/IoTCommsFrameFormat/SecureBasicFrame-V0.1-201601.txt

But don't think that this paragraph

*868.35MHz 5kbps OOK "FS20" carrier, unwhitened, no hardware CRC/checksum,
 with a preamble of aaaaaaaa and sync of cccccc. In this case the payloads
should avoid long runs of 0x00 or 0xff bytes, and there should be no more
than one trailing 0x00 (more may be stripped), ie should be somewhat
self-whitened. Note however that the leading length byte may make for
tricky interop with existing FS20-carrier OpenTRV comms.*


reflects the current Radbot Radio parameters.  Is there another document
I'm missing, or do I need to dig into the code and reverse engineer from
the transmitter setup?

Thanks for any pointers,
Rob.
