■ Testing Notes: This unit has been tested with internal batteries. The digital LCD frequency counter tracks smoothly and accurately across all bands as the "Tune" and "Band" knobs are rotated.
■ Power Source: This specific version is configured to use 9V batteries.
■ Internal Condition: The unit has been inspected internally; the battery connectors and circuit board are clean and free of any acid corrosion or leakage damage.
■ Cosmetic: As a vintage piece of technical gear, the faceplate and casing show some typical surface scratches and wear from professional use (please see high-resolution photos for exact detail). All labels are clear, and all controls feel firm and responsive.
Product Features ■ Frequency Range: Continuous coverage from 1.8 MHz to 170 MHz, covering 160 Meters through the 2-Meter band.
■ Versatility: Triple-function tool: SWR Analyzer, RF Resistance (Impedance) Meter, and a standalone Digital Frequency Counter.
■ Analog Precision: Dual analog meters provide immediate, real-time feedback, which many operators prefer over digital displays for finding resonance "dips" quickly.
■ Power Options: Operates on internal 9V batteries or a standard external 12V DC power supply (neither are included).
