The

FTABLE key accesses five functions. The menu is:

Partition allows you to select one of sixteen separate tables (numbered 00 to 15) as the "active

partition".

Size displays a count of all frequencies currently in memory in all tables, including those

which have been deleted but not restored during

SCAN. ESC exits, or, by entering a new value (a

positive number or 0) you can remove (and restore) blocks of frequencies on a last in first out

basis, or purge all tables at once. In some software versions this “coarse” control is not provided,

but the size of the current active partition, as well as the master table, is reported.

Add accepts frequencies (in MHz) from the keyboard and adds them to the "top" of the active

partition. Note that some application programs, which assign "channel" numbers to frequencies

in the active partition, number the frequencies sequentially, in the order in which they are

entered, while others (e.g., W16) request a unique channel number for each frequency entered.

Delete steps through the active partition one frequency at a time and offers the option to

delete or continue. In some software versions this item is called Del/View and allows scrolling

through the frequency table using the arrow keys.

Copy causes all frequencies which have been deleted, but not restored, while scanning to be

written back into the active partition. Frequencies deleted by the

FTABLE/Delete command

cannot be recalled in this way, but must be re-entered using Add.

Some SRX_400 software versions provide a facility for uploading frequency tables from disk

files via the serial port. If your software supports this feature a continuation arrow (“->“) will

appear on the lower right in the

FTABLE menu, and the selection Upload table from Host will be

presented on a second menu page.

In order to use this facility you must first create a text file (ASCII format), containing a list of

frequencies and corresponding partitions, using any ASCII editor. Most word processors, and

many database and spreadsheet programs, provide ASCII text files as an output option. Program

editors, and simple editors like Windows Notepad or DOS Edit, will produce ASCII files by

default. The file should have the attribute .TXT with the data arranged in lines, as shown below

(comments in italics are not part of the file):

148070 (Frequency 148.070 MHz; partition defaults to 0. )

148090 0, 1, 2, 3 (Frequency 148.090 Mhz in partitions 0,1,2,3. )

148110 1 (Frequency 148.110 Mhz in partition 1 only)

Note that both the space character and the comma are valid separators (as is the TAB).
