[Elecraft] [KX3] ADC/DAC access, keyer input

[Wayne Burdick]

Hi Fred,

The RX analog I/Q output jack adds very little to the cost. It's a standard feature. 

Internal option modules include the ATU, roofing filter, and internal battery pack with real-time clock (RTC). 

(Totally off-topic: The RTC can wake-up the radio at a programmed time, turning the KX3 into a high-performance clock radio :)

73,
