A red LED may also be due to: Rig Control is ON but ProLog cannot communicate with the radio or the "Logging Mode" has been set to Manual.  All of the setup parameters associated with Rig Control are in the Rig Control section of the "Configurations" menu.  Whenever Rig Control is disabled the Rig Selection pulldown list is disabled (grayed) as well.

ProLog's Rig Control operates in one of two modes: User Initiated or Auto-Poll.  In User Initiated mode, ProLog updates the operating frequency and transmission mode only when you clear the logging form using the CTRL+SPACEBAR key combination or when you depress the ENTER key after you have entered a call in the Call field of the primary logging form. 

In Auto-Poll mode, ProLog acquires the frequency and mode information on a recurring basis.   Every three seconds or so, based on the rate setting, ProLog will poll the radio and update the Freq, Band and Mode fields of the logging form with the current information received from your radio.  The only exception to this is when you activate the Digital mode checkbox in the Rig Control panel.  Switching ProLog into one of the digital modes will cause ProLog to maintain the selected digital mode regardless of what mode changes are made at the radio.  Frequency information however continues to be tracked and displayed.

Auto-Polling is automatically suspended whenever:

    1) The cursor is positioned in the Freq, Band or Mode fields of the logging form.  ProLog assumes that when you move into one of the aforementioned fields, it is for the purpose of changing the current setting(s) of your radio.

    2) A previously worked contact is displayed in the logging form.

    3) The Logging Mode is set to "Manual".

You can toggle the state of Auto-Polling using the Polling button in the Rig Control panel of the logging form.  The LED to the right of the Polling button will be green when Auto-Polling is enabled, red when it is disabled.

ProLog allows you to change the frequency and mode of your radio directly from the logging form.  Move the cursor into Freq field and enter the frequency followed by pressing the ENTER key, then click on the Mode pulldown list and select the  desired transmission mode from the list.  Your transceiver will be switched to the new frequency and/or mode.

The current status of Rig Control and Rig Polling can be determined by the state of the LED's in the Rig Control panel of the logging form.   Adjacent to each LED is a button that may be used to turn Rig Control and/or Rig Polling On or Off.  Note: The default settings of the Rig Control and Polling Activation Status LED's are determined by the associated setting in the "Rig Control Configurations" menu.  Even though you may dynamically change the default settings during your logging session using the buttons, the state will always revert back to the default settings in the Rig Control Configurations menu whenever ProLog is launched. 

For each active logbook, ProLog maintains an internal list of 30 user programmable memory channels permitting you to setup and access your favorite frequencies and modes at the click of the Memory button.
