3. The signal quality (bytes 26-27) is a numeric value from 0
to 99 representing the data quality of processed data
samples during the averaging time.
For example, a value of 99 signifies that all data samples
were determined to be valid and processed during the
averaging time. If some samples were determined to be
"missing", these samples were not processed and the
reported signal quality is a proportional value less than 99.
4. Bytes 28-29 are the modulo 256 hexadecimal checksum of
the ASCII values calculated for bytes from 2 to 27.
Example:
WAP2131870503012.6014.7K99xx
