[NCARC] TX-6 data format

[Michael Robinson]

I have one of those cool atomic clocks with the projector and outdoor 
temperature remotes.
The remote is labeled 433Mhz.
TX-6, which is a standard remote transmitter usually used for 
temperature, transmits on 433.92Mhz.
What I hear on my HT at that frequency is a burst of data tones from my 
remote.
But I also hear lots of other data being transmitted in bursts.

What is the rf mode?
What is in those other bursts?
What are the data formats?
I can discern about 4 different types.
