Some personal computer firewall programs block application-initiated FTP sessions. You may find it necessary to negotiate with your firewall to allow the K-Pod Utility (K-PodUtility.exe) to initiate FTP sessions to copy files from Elecraft's FTP server.
Your firewall may require the IP address of a "trusted site" to enable FTP. The Elecraft FTP server IP address may be obtained by typing ping ftp.elecraft.com on a command line.
