[GCARC] Fwd: [KPA1500] KPA1500 Panic Button: Forcing a Firmware Load

[Al KB2AYU]

Before we left the Clubhouse around 4PM I did a remote session while 
sitting in front of the amp and all was well.

However, there does appear to be a gremlin lurking about.

John, have you contacted  Elecraft about this?

>> If you are in the middle of a contest and suddenly there is no output (zero output, zero VSWR), don't panic, try the "Forcing a Firmware Load" procedure on p-38 of the manual.

>> Pressing and holding the front-panel AUX key for more than 10 seconds opens the "KPA1500 Utility Program" to the "Firmware" tab, which you may also do manually (necessary if you are operating remotely).  Click the "Check Version Now" button.  The utility won't be able to read the current version if other software is connected to the port required.  Click the "Send Firmware to the KPA1500" button after the current version appears.  You will be notified when the firmware has been restarted.

What could cause that?  I know that we have an issue with RFI in the shack. I suspect that the firmware memory was contaminated by static charge.  It took three days for it to return to normal.
