Dense-Pack and Standard DM format is that Dense-Pack uses a
condensed searcher packet instead of the normal DM format.

LOG_THR
When the Retriever Pilot Scanner is logging in Standard DM format,
the serial link is limited in the number of searches which can be
logged to an external device such as a DM or the Interface Tool. For
instance, in a commercial AXESSTEL phone, link bandwidth
limitations result in roughly a one-tenth undersampling during
search logging. That is, the external device can log only about
one-tenth of the actual number of searches the phone performs. In
Retriever, this effect is even more pronounced since Retriever uses
special hardware and software features to increase several fold its
average search scan rate over a conventional commercial phone.
To log only the most interesting searches Retriever Pilot Scanner
sees, a thresholding feature is provided, applicable only to
Standard-AXESSTEL logging mode. The log_thr parameter
controls what threshold is used. The choices are as follows:
_
If log_thr=1, the Over-the-Air T_DROP threshold is used to
weed out searches. Retriever will not log searches whose energy
is below that threshold.
_
If log_thr=2, the Over-the-Air T_ADD threshold (generally a
higher threshold than T_DROP) is used. Retriever will not log
searches whose energy is below that threshold.
_
If log_thr=0, no thresholding will be performed. Retriever will
attempt to log all searches with the resultant undersampling.
