Parameters

• Power at Antenna: (watts)
• Mode duty cycle:
  Conversational SSB, no speech processing (mode duty cycle=20%)Conversational SSB, heavy speech processing (duty cycle=50%)Conversational CW (duty cycle=40%)FM (duty cycle=100%)AM (duty cycle=100%)FSK/RTTY (duty cycle=100%)AFSK SSB (duty cycle=100%)Carrier Always On, i.e., for Tuning Up (duty cycle=100%)For all others, or if unknown, assume worst case scenario (duty cycle=100%)
• Transmit duty cycle: (time transmitting)
  You transmit for 123456789101112131415161718192021222324252627282930 minutes then receive for 0123456789101112131415161718192021222324252627282930 minutes (and repeat).
• Antenna Gain (dBi):
• Operating Frequency (MHz):
