Elecraft W2 is a versatile, auto-ranging RF power and SWR meter that utilizes remote sensing. Up to two remote sensors can be attached, with various power and frequency ranges available. Sensors use standard CAT5 shielded or unshielded cables.

Versatile Auto-ranging Power/SWR Meter


The Elecraft W2 wattmeter provides the fast, high-brightness LED bar graphs you need to keep track of transmitter and amplifier performance. With four power ranges (2/20/200/2000 W), the W2 can satisfy the needs of both QRO and QRP operators. The compact, attractive display unit will fit just about anywhere, requiring only 10-14 VDC and sensor cables.


Remote Sensors for Any Application


RF sensors for the W2 can be placed near the transmitter’s output, minimizing coax length. Two sensors can be connected to the W2, if required, to monitor different transmitters or ampfliers, switch-selected from the front panel. Sensors optimized for 144-450 MHz and HF-6 m are available, with two different power ranges. The sensors use standard CAT5 shielded or unshielded cables.


Amplifier Keying Control and Alarms


The W2 can be configured to generate alarm outputs at  a high SWR. It also includes a fully-isolated amplifier keying cutout relay. On any alarm condition, the amp’s key line can be broken, preventing possible damage to sensitive equipment.


Remote Control and Data Measurement


The W2’s built-in RS232 port allows you to use a computer to read both power and SWR with higher accuracy, as well as to set and check alarms, turn the LEDs off, and other operations. You can use the supplied PC software, or write your own remote-control applications. The W2’s RS232 drive circuitry is intended for short cable lengths (typically 6’), but you can also use the Elecraft KUSB or other USB-to-RS232 adapters, greatly extending the control cable length when required.
