SPECIFICATIONS
3.5 to 4.1 MHz, 7.0 to 7.6 MHz, 13.9 to 14.5 MHz, 21.0 to 21.6 MHz
and 28.5 to 29.1 MHz; accessory crystals are available for the 28.0
to 28.6 MHz and 29.1 to 29.7 MHz segments of the 10 meter band.
Lower Sideband, Upper Sideband, AM and CW.
Total drift is less than 100 Hz after warm up. Total frequency change
is less than 100 Hz for a + 10% line voltage change.
+ 650 Volts DC at 300 mA average and 500 mA maximum with 10%
regulation from 100 to 500 mA and a maximum ripple 1%.
+ 250 Volts DC at 200 mA with 10% regulation from 170 mA to
200 mA. This includes the effect of the 650 Volt supply change if
both voltages are obtained from the same transformer. Maximum
ripple must be less than 1/4%.
-45 to -65 Volts DC adjustable filtered bias into 33 K Ohm load.
12.6 Volts AC or DC at 5.5 Amperes.
Nomina! 52 Ohms (VSWR less than 2:1).
Better than + 1 kHz when calibrated at the nearest 100 kHz calibra-
tion point.
