OVERVIEW

Operate any K4 station, from anywhere. Our new, highly portable K4/0 gives you complete remote control of the high-performance Elecraft K4 transceiver, whether from the comfort of home or out on the road. The remote K4 can be located anywhere the RF action is—at a site with an extensive antenna farm, on a mountaintop, even in a DX hot-spot. You’ll have new “ears” you only dreamed of!

Connecting to a remote K4 takes just seconds. Just tap the globe icon on the K4/0’s front panel and select a server radio from your list. You’ll need each K4’s IP address (or network name) and a password created by the owner.

No interface devices or third-party server required. The K4/0 uses the peer-to-peer protocol built into the K4, allowing the radio to act as its own server.

Compact and lightweight. At only 4” (10 cm) deep, the K4/0 is sized-right for a small home station, RV, hotel, or picnic table. It’s also easy to carry, weighing in at about 4.5 pounds (2 kg) and fitted with a handle. Optimize your viewing angle with the folding tilt feet, or place on a shelf. Low power requirements and an optional battery pack providing up to 4 hours of operating time.
