Hello Mike: Depending upon the environment, some older K3 rigs suffered from oxidation of the contacts on the connectors. In your case I'd suspect the connectors between the front panel and the main RF board.
Simply removing/replacing the front panel should take care of it if I'm correct. The simple procedure is described in the K3 kit assembly manual on the Elecraft reflector here: http://www.elecraft.com/manual/E740259%20K3s%20Assembly%20Manual%20Rev%20B1. pdf See page 41. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Mike Crownover Sent: Friday, May 27, 2016 8:01 PM To: elecraft@mailman.qth.net Subject: [Elecraft] FPF problem I have a K3 that has been sitting on shelf for a while. I powered it up today, after it was on for ~5 minuted, I get a ERR FPF. After a little research I learn I need to reload the flash file. I used the utility to update the MCU and then when the FPF tried to load I got this message. Elecraft K3 Utility Revision 1.15.12.7 OS Version 10.0 Build 10586 K3 MCU revision 05.38. RS-232 speed 38400 bit/s. Waiting 4 seconds for flash memory erase Sending firmware file C:\Users\ad5a_000\AppData\Roaming\Elecraft\K3 Firmware\hfpf0125.hex to FPF Error code 0xE2000048: No response to poll while synchronizing to buffer boundary FPF verification failed. Reload FPF. Click "Close" to close this window I have retried numerous times and get the same message. Any ideas.
