- Launch the fanticipator.exe application from the shortcut (did you make a desktop shortcut during install?) or Windows File Explorer
- If your configuration is correct, the status fields in FANticipator should immediately reflect readings taken from the KPA1500
- When you close FANticipator (the X in the corner) the settings and screen position will be saved to the fanticipator.xml configuration file
- Version 1.0 of FANticipator enables the fan speed controls During Tx, AfterTx Setting #1, AfterTx Setting#2 and the KPA1500 settings for Operate/Standby, Antenna1/Antenna2, ATU In/Bypass/Tune
- When used with KPA1500 firmware release 01.72 or later, a Fault condition can be cleared by pressing the Operate/Standby button
Explanation of Fan Control Options
During Tx, override fan menu settings and run at settings +1
K8UT thinks that fan noise is more tolerable when transmitting – especially in CW and digital modes. With this option enabled, the fans will always run when the amplifier is in Transmit mode. The fan settings will always be one stage faster than the default. Thus, when the fans should be off they will be at setting #1; when they should be at setting #1 they will be at setting #2, and so on.
After Tx, continue to run at setting #2 until below nn degrees C
K8UT thinks that running the fans at low speeds for longer periods of time will avoid the fans ever reaching their very loud settings. With this option enabled, the fans will run in receive at their setting #2 level (which is somewhat loud but not awful) until the amplifier temperature has dropped below the indicated temperature.
After Tx, continue to run at setting #1 until below nn degrees C
K8UT thinks that running the fans at low speeds for longer periods of time will avoid the fans ever reaching their very loud settings. With this option enabled, the fans will run in receive at their setting #1 level until the amplifier temperature has dropped below the indicated temperature. At that time the fans will turn off (setting #0).
FANticipator Sample Screenshot Description
Refer to the image above when reading this description:
The amplifier is in transmit mode (red Tx) on 17 meters (18 MHz), with an input of 23 watts producing an output of 1054 watts into an antenna with a 1.1:1 SWR. The amplifier temperature is 55 degrees, and the fans – which would not usually be running at this temperature – are operating at setting #2 because the During Tx option is enabled. When the amplifier returns to Receive mode (green Rx), the fans will continue running at setting #2 because the After Tx setting #2 option is enabled with a cutoff off 50 degrees. When the amplifier cools below 50 degrees the fans will be reduced to setting #1 because the After Tx setting #1 option is enabled with a cutoff off 35 degrees. When the amplifier cools below 35 degrees the fans will automatically shut off (setting #0) and the shack will be silent once again.
- If FANticipator complains about not connecting to the amplifier
- Use the KPA1500’s menu to display the NET IP ADDRESS of the amplifier. If you are using DHCP the router may have changed its address assignment
- Open a DOS windows and run the PING command to see if your KPA1500 NET IP ADDRESS is correct. For example: PING 192.168.1.123 <return>
- If FANticipator immediately closes (never opens its window), there is probably something wrong with the fanticipator.xml config file. Delete the fanticipator.xml file and re-launch the program. A replacement XML file will be created automatically
