Preface to the Examples

The following exercises are designed to enhance familiarity with Suretrack receiver functions and

operating modes. They are modeled as faithfully as possible on real applications and include a

basic radio tracking session.

Tracking

You are studying caribou populations on a group of islands off the Labrador coast. There is

some physiognomic evidence that these populations have experienced some degree of isolation,

but a quantitative measure of their independence, and in particular the impact on their genetic

viability of a proposed mainland development, cannot be assessed without some behavioural

data. You have 200 animals instrumented with radio collars, 50 on each of four islands. The

transmitters are at individual frequencies spaced 10KHz apart. Your method is to overfly the

islands twice a week (weather permitting) and try to locate as many of these animals as possible.

One strategy that occurs to you is to install your frequency list in four separate partitions of

the scan table, one for each island. This will keep your initial search list small, your "round

trip" scan time short, and your probability of missing an animal while your receiver is

scanning through a largely inactive list as low as possible. You recognize, however, that in

order not to bias your experiment, you will need an efficient procedure for finding animals

which have "jumped" islands, so you have reserved a partition also for the complete list, one

for a combination of the lists from islands 1 and 2 (which are close together), and one for a

combination of the lists from islands 3 and 4 (which are closest to the mainland, though

distant from each other). This gives a total of 7 tables.

PROCEDURE: SELECT TABLES AND ENTER FREQUENCIES

From the command environment, press

SHIFT

F TABLE

The display will prompt you to make a selection using one of the numbered keys. To select the

table you want to be active, press 4. The display will prompt you to make a selection of a table

where you wish to store the frequencies, and will make this the active table.

Press the desired number between 00 and 15. After you have entered a two digit number the

F TABLE menu will once again be displayed.

Press

to "add" frequencies.
