DC Voltage Chart
Voltages are approximate and will vary up to +/- 10% due to normal component variation without
affecting the operation of the KRC2. Measurements were made under the following conditions:
KRC2 powered by K2, K2 powered by a 14.0 V (measured) power supply, K2 powered on, set to
14290.9 MHz. Switch to this band from another after powering on K2/KRC2 combination.
Nothing attached to the KRC2’s DC barrel jack or PC DB9 connectors. No wires attached to the
J4-J13 terminal connectors. Measurements taken with Metex ME-22 Digital Volt Meter.

Note: U6 Pins 4, 5, 6, 7, 14, 15, 16, 17 and U7 Pins 4, 6, 7, 14, 15, 16, 17 are floating (not driven)
with no pullup. U6 pin 5 is driven to zero for 14 MHz as shown in the voltage chart.
