Antenna Tuner/SWR & Power Meter SWR: 1:1 to 1:3 Dual Metering FS Antenna Tune Control Forward & Reflected Power Switch 0-10 Watt or 0-100 Watt Range. Antenna Tuner/Power Meter. The Texas Ranger Elite TRE-936FFC is one of the latest radios featuring the "new circuit design" concept by Ranger Communications, Inc. Built with ruggedness, durability and reliability in mind, this model will answer your needs for a high performance radio for those interested in AM only operation. The TR-936FF C features Ranger Exclusive new Advanced Noise Filter Circuit for improved signal to noise ratio, providing high noise rejection capability that others just claim they have. This one works! You will instantly notice marginal signals pop in better when you turn on the switch and listen to your reception with a quieter signal. The Advanced Noise Filter circuit de-emphasizes the audio high frequency response in order to increase the signal-to-noise ratio of weak signals.

PDC1 SWR/RF Test Meter. The RPSWR-2 is a compact meter designed to indicate the condition of any 52 ohm antenna and antenna coax used for Citizens Band radio operation by testing for the Standing Wave Ratio or relative RF Power. High resolution power and SWR readings are also available through a connector as RS232 serial data for display on a computer. (This interface uses a simplified RS-232 style interface that can drive short cables of less than six feet or directly to a USB adapter.) Elecraft will also be supplying a W1 compatible USB adapter as an option for the W1. The LEDs can be turned off under computer control for use as a dedicated remote computer read Wattmeter / SWR Bridge. This provides you with the ability to receive those marginal signals with much more clarity and understandability. Combined with the Noise Blanker and the Automatic Noise Limiter, this has to be the quietest mobile stations ever manufactured.
