There's really nothing special about a .dat file from an R7 vs. a .dat
file from some other Trimble receiver.

Only use the 'week' option if you absolutely sure you have the right
week value for the start of the data.  In most cases, you won't need
to use this option unless teqc suggests that it might be necessary.

Trimble stores the antenna type in the .dat file as a 2-letter code.
Either the translation for any particular code to the more usual IGS
ASCII text description is built into teqc, or it isn't not.  (If not,
the antenna type in the output RINEX obs file is not populated with
anything useful unless you are using the '-O.at' option to specify
your own ASCII text description of the antenna type.)

The only thing strange here is that the .dat file has two different
2-letter codes for the antenna.  Did you do an antenna swap in the
middle of data collection?

Your .dat has a record 40 (0x28) that teqc knowns nothing about.
Nothing to worry about.
