The clone memory image read from the transceiver includes far more than just the main memories. Because the program uses the radio's Clone function to upload changes to the memories it is necessary to acquire an up-to-date image otherwise you will find other settings may be changed back to an earlier state.
The recommended sequence of events is:-
a) make a backup image of the receiver using the 'Read FT7900' button
b) make changes as detailed below
c) perform a restore of the amended image to the receiver
Display the memories by clicking on the Memories tab. Each of the cells in an occupied row can be edited in-place.
a) use the mouse or cursor (arrow) keys to select a cell to change.
b) double-click a cell or press function key F2 to switch to edit mode.
c) type your change or, for mode or step, select from the options in the drop-down box, then press Return or Enter.
CTCSS tones and DCS codes
When the CTCSS and DCS columns are not applicable because no encoding method is specified they are 'greyed out' and are not editable. When an encoding method is used other than OFF you can change them.
Likewise the CTCSS TX and DCS Tx columns are 'greyed out' and not editable until the RPT Shift setting is set to Split. These two columns then allow you to set different CTCSS tones or DCS codes for TX and RX.
When the RPT Shift is set to Split and the Encoding Method is TONE or TSQL the CTCSS column contains the RX CTCSS tone and the CTCSS Tx column contains the TX CTCSS tone.
When the RPT Shift is set to Split and the Encoding Method is DCS or D the CTCSS column contains the RX CTCSS tone and the CTCSS Tx column contains the TX CTCSS tone.
There are two quick setup commands on the Memories menu for using separate CTCSS tones or separate DCS codes. They are 'Setup memory for separate CTCSS tones' and 'Setup memory for separate DCS codes. The keyboard shortcuts are CTRL + M and CTRL + N.
Keyboard editing shortcuts
A single cell in the Memories grid can be copied and pasted into another non-Empty row using the keyboard sequence CTRL+C to copy the current cell followed by SHIFT+INSERT then ENTER to paste into another cell in the same column.
The columns that have drop-down selections for setting can be 'block filled' with the same information very quickly. First of all highlight the cells to be filled by dragging over them with the mouse. Then select the value you want from the drop-down selections. When you move to another cell the value you selected will be filled down in the cells you highlighted as long as the memory is not 'Empty'. If you have got one or more Empty rows then those cells are ignored in the fill process.
The following screen image shows the CTCSS tone being changed using the drop-down list of values.
The Memory Description column
The radio itself does not hold any of the information you enter in the Memory Description column. When you save a memory image to disk the program writes the memory descriptions to a separate file with the characters dsc added to the end of the filename. When you later read the memory image from disk the information you entered in the Memory Description column is automatically read along with the main memory information file.
When you read a memory image from the radio the Memory Description column will be empty. However, you can add the memory description information from another disk file. After reading from the radio has completed click the Read Disk File button; change the 'Files of type' drop-down in the Open dialog box to 'Description Files' and choose an appropriate filename.
