Description

WV Communications 70-01FD-CH 19" Rackmount 70 MHz FM Modulator RF/IF Demodulator

This rackmount chassis houses two modules: a 70 MHz FM modulator and an RF/IF demodulator. It converts between baseband audio signals and 70 MHz RF carriers for telecom and broadcast equipment.

Specifications & What's Included

  • 19" rackmount form factor
  • 70 MHz FM Modulator module (70MDF-FM-BRZ)
  • RF/IF Demodulator module (RF/IF-DEM-PANAM)
  • Selectable center frequency: 69.6 MHz or 70.0 MHz
  • Power: 115 VAC, 1-phase, 47-63 Hz, 1A SB fuse
  • Front panel controls: FM sensitivity and output level adjustments
  • Status LEDs: AC PWR (green), FAULT (red)
  • BNC and DB9 connectors on rear

Applications

70 MHz intermediate frequency modulators and demodulators are used in microwave and satellite communication systems, RF distribution networks, and telecom transmission equipment. This unit was designed for systems requiring FM modulation at 70 MHz, commonly found in professional broadcast and point-to-point radio links. Compatible with equipment supporting standard 70 MHz IF frequencies.

Condition: Used
This WV Communications 70-01FD-CH 19" Rackmount FM Modulator / RF-IF Demodulator Chassis has been inspected and appears to be in good condition. The gold-anodized aluminum enclosure shows light surface wear consistent with prior rack use, but there is no significant damage visible. Both installed modules — the 70 MHz FM Modulator (70MDF-FM-BRZ) and the RF/IF Demodulator (RF/IF-DEM-PANAM) — are present and seated in the chassis. The interior components, PCBs, and RF subassemblies appear intact and undamaged in the photos. Please view our photo set and contact us if you have any questions.
