2.1 Printout HEADER

: Enter the header for all the pages of your book printed by the program. If you don’t

change what it initially says; the program will continue to nag you to set User Preferences.

2.2 Center Latitude/Longitude:

Enter the general area you fish in. The program needs to know the general

location of your working area in order to correctly do Loran to Lat/Lon conversions and to check for errors in data entry.

Why, you ask? Well, in general, there are two or more valid solutions to the equations for a given set of Loran numbers.

That is, the Loran lines can cross in more than one location, so the same Loran numbers can exist in two widely

separated locations. To compute the right solution you need to give it an initial guess. For the center, pick a point in the

area you fish and enter the approximate Latitude and Longitude. Use positive numbers for N and W and negative for S

and E. Yes, that is contrary to international standards for longitude. You can enter Lat/Lon numbers in any of several

forms:

• DD.DDD degrees (and fractions)

• DDMM.MM or: DD MM.MM degrees, minutes with or without a space or dash

• DD MM SS.SS degrees, minutes, seconds with two spaces or dashes

2.3 Inlet Latitude, Longitude and, Name:

Enter the name and location of a frequently used inlet for use as

a reference point in Range and Bearing calculations.

2.4 Hide Loran Features

If you don't want to see Loran based features, then push this button. It hides all Loran information, to simplify the

display. It then makes the next two settings disappear.

2.5 (Loran) Chain Choices:

The program needs to know what Loran chains you will be using; both to check

your entries and to do the calculations. Typically, the installation is pre set with the appropriate chains for the section of

the country you are in. See the reference chapter to get more details on programming chains if you are in another part of

the world or you are going to take a trip far from home.

2.6 Set Favorite (Loran) Chain

: The Loran Chain number is an artificially selected number from 1 to 8 that

only has meaning to this program. On the chain spreadsheet of the User Preferences window, click on the row of the

Loran chain you will use most frequently. This will highlight it in red. It will be the default chain choice for new files,

but each file can have its' own favorite.
