[Elecraft] P3 Questions

[Robert Bajuk]

>From the P3 instruction manual:

When used with a K3, this power may be taken from the 12VDC OUT jack on the
K3 rear panel. The K3 is capable of supplying power to both the P3 and the
Elecraft PR6 six-meter preamplifier at the same time if 12VDC or greater is
supplied to the K3’s power connector.
Lower voltages at the K3 connector will cause the total current required by
the P3 and PR6 to exceed the 500 mA limit from the K3’s 12VDC outlet.

P3 requirements:
Power: 10-15 VDC is a standard 2.1 mm barrel connector for a 10-15 VDC
supply capable of delivering up to 0.5A.
