The Memory Grid


A spreadsheet-style memory grid is shown in its own window by clicking the Mem Grid button at the top right of the main window.

The contents of the grid are automatically saved and restored each time you close or open the window.



The first time you start the program the grid contains only one entry. Use the Edit menu to insert/change/delete/move etc.

Adding the current operating frequency details to the grid

When the main screen has the focus you can add the current frequency details to the beginning of the Memory Grid by pressing the F4 key. You must not be in the middle of scanning, doing a spectrum scan or transmitting. The Memory Grid is automatically shown, and any filters that were applied are cleared. A description of 'Added using F4' is made so you can identify how the entry got there.

Adding a CSV file of frequencies to the grid

By clicking the File menu and choosing the 'Add a CSV file to grid' command you can import a previously saved collection of memories - and either add to the existing grid entries or replace the current contents. For Short Wave Listeners there is a sample CSV file of nearly 1,400 frequencies called SWL1.CSV. These frequencies have been obtained, with permission, from the web-site of Daniel Sampson.

Saving all or part of the Memory Grid as a CSV file

To save the memories grid as a CSV file use either 'Save All as a CSV file' or 'Save Filtered as a CSV file in the File menu. The contents of the grid are saved in the same CSV format as used elsewhere in the program. Save Filtered only saves those rows that are visible in the grid, Save All saves all rows whether they are shown or not.

Setting up for split frequency or cross-band working

Because the grid has separate receive and transmit frequencies and modes, you can set up in-band or cross-band split frequency memories.  For rigs that support a Split Frequency command the program performs a full hardware setup for split mode working, putting the transmit frequency into VFO B, the receive frequency into VFO A, and putting the rig into Split mode. The FT-847 has no CAT command for Split mode nor for switching to VFO B, so the program does a software emulation and changes frequency between receive and transmit.  This means that you must use FTBCAT's transmit button to key the rig for an FT-847, whereas for the other rigs you can use whatever method you prefer.

Sorting the Grid by column

The memory grid can be sorted on any column by clicking on the column heading.  The first click will sort ascending, the second click will sort descending.

Deleting an entry

To delete a memory, click anywhere in the row of the memory you want to delete and then press the Delete key. To prevent accidental deletion you will get an 'are you sure' type message.

Editing entries in the Grid

To edit a memory, either double-click on the memory you want to edit in any column except the first one, or use the Edit command on the Edit menu.  The Group, Scan and Description fields can be edited 'in situ' by typing directly into the desired cell.



Reorganising the position of an entry

The Edit menu contains commands to Copy, Insert, Move and Swap entries in the Grid.

Tuning the rig to a memory

To GoTo a memory, select the desired memory and then click the GoTo button, or double-click the desired memory in either the first (Memory) column or the last (Description) column.  

Alternatively, you can use the left arrow key when in the first column, or the right arrow key if in the last column; the GoTo action is performed when you release the key, not when you press it.

Filtering what is shown in the Grid

Use the Filters to control which memories you see in the grid. 

There are filters for lowest and highest frequency, operating mode and two Group identities. 

Group identities can be 0 to 9 or A to Z, so there are 36 different groups. 

Each type of filter can be either 'applied' or not. By using the filters you can show subsets of a memory grid. 

To clear all the filters and show all of the memories in the grid, choose the 'Clear all filters' command from the View menu.  

Using the filters to control which frequencies are scanned

The 'scan grid' option on the main screen is used in conjunction with the Scan indicator in each grid entry.  Only those entries that are currently shown are scanned - anything hidden due to filtering is not included in the scan.

If the grid does not show on-screen

It is possible for the Memory Grid window to be accidentally moved off the Windows desktop area.  If this happens then use the Tools menu and select the 'Reset Memory Grid position' command. The next time you display the Memory Grid it will appear at the top left-hand corner of your screen.
