• Automatic antenna selection from network-based UDP packets or hard-wired BCD inputs
  
  • In N1MM+ – use the antenna numbers from the Configurer Antenna table
  • Supports the N1MM+ Keyboard Shortcut for multiple antennas per band by toggling <alt>+F9
  • In Logger 32, DXLab, Log4OM, UcxLog, TR4Win or N1MM+ – use the Tx radio frequency from the UDP RadioInfo packet
• Manual antenna selection with simple mouse clicks in the Windows FreqEZ Console
• Hard-wired method, for logging programs that do not support UDP broadcasts
• One of these units will drive all the ports of either the 2x6 or 2x8 switch boards
