Header:
- Byte 0, most 4 significant bits: Packet Information
- LL_ACK_FLAG 0x10
- LL_RESENT_FLAG 0x20
- LL_RELIABLE_FLAG 0x40
- LL_ZERO_CODE_FLAG 0x80
- Bytes 0, (4 least significant bits) to byte 3: Packet ID, assigned by circuit
- Everything beyond this is zerocoded for compression
- Bytes n thru n+(frequency size)
- 1/2/4 byte ID of the message the packet contains
- Bytes n thru n+(data length)
- Body of packet, possibly zero coded.
- Bytes n+(data length) thru acks
- Rest of packet is fill with as many acks as will fit from reliable messages
