Current drain
Receive 35 mA typ., 40 mA max (headphones,
LED display timed out, 30-m or
30/80-m option installed)
Transmit 300-700 mA (varies with supply
voltage and power output setting)
Bands covered (MHz) 1
Receive 5.0-9.5 and 12.0-16.5 MHz
Transmit 7.000 to 7.300, and 14.000 to 4.350
MHz; spurious content at 3 to 4 w, 2
nd
harmonic -40 dB typ. with LPF
adjustment (see page 59)
Frequency control DDS with 50 MHz crystal reference
VFO drift < 50 Hz per hour after 5-minute
warm-up at 25° C
Display 3-digit LED w/bargraph mode;
1 KXB30 option adds 8.0-12.5 MHz receive and 10.1-10.15 MHz transmit.
The KXB3080 option covers the same range as the KXB30 and adds 1.5-5.5
MHz receive and 3.5-4.0 MHz transmit. Adding either module also greatly
improves sensitivity in the 49-meter band (5.9-6.4 MHz).
