Elecraft PR6-10 (22-54MHz pre-amplifier for K3)

The PR6-10 is a high-performance, low-noise preamp that can be used with the Elecraft K3 or other transceivers for added gain on the 10 Meter and 6 Meter bands. Note that the K3S has similar functionality built into that radio.

It's especially well-suited for the K3, which has exceptional dynamic range, yet can benefit from additional gain for weak signal work. The noise figure of the preamp itself is typically 0.7 dB.

Power for the PR6/PR6-10 can be obtained from any 11 to 14 VDC supply. When used with a K3, the PR6/PR6-10 can be powered from the switched 12 VDC accessory output.

When used with the Elecraft K3, the K3 must be equipped with the KXV3 option. The PR6/PR6-10 can be connected directly to the KXV3 RX ANT IN/OUT jacks on the K3's rear panel where it can be switched in automatically by the transceiver on the desired bands. A second pair of jacks is provided on the opposite side of the PR6/PR6-10 to allow use of the K3's normal RX ANT IN/OUT signal path when the preamp is not in use.

The PR6/PR6-10 can be strapped permanently ON, or it can be turned on and off externally from an open-source/open-drain logic signal. When used with an Elecraft K3, the DIGOUT1 control line on the 15-pin ACC jack can be used to enable the preamp on the desired bands. Please refer the K3 Owner’s manual CONFIG menu description for DIGOUT1 details.

The PR6/PR6-10 is housed in a rugged, custom-machined enclosure.
