PRC-178A Data Sheet

MORCOM PRC-178A Tactical VHF Transceiver3656 Centerview Dr. Unit # 1 • Chantilly, VA 20151, USA • www.MORCOM.com Phone: (703) 263-9305 • Fax: (703) 263-9308 • E-mail: info@morcom.comThe VHF low band between 30-88 MHz facilitates one of the most effec-tive wireless communications avail-able to defense forces, tactical teams, or special law enforcement teams for medium distances (2-10 miles). Due to its longer wavelength, this frequency band can reach considerably longer distances than the conventional VHF band of 150-174 MHz. Because of its longer range and ability to go around obstacles, low band is routinely used by armies around the world.The PRC-178A portable hand-held transceiver utilizes leading edge technology to package advanced features like Full-range Scan, Programmed Scan, and Selected Frequency Scan in a rugged but yet affordable unit. This radio is fully compliant with military specifications including full immersion in water. MIL-STD810 E and F are the highest standard for rugged testing for mobile-communications equipment.In addition, the PRC-178A has the following features:• Operation over the full VHF Military Band• Up to 10 Programmable Channels• CTSS and DCS Tone Signaling• Whisper Function• Functional Keypad• PC Connection• Full-range Scan, Programmed Scan, and Selected Frequency Scan• Built-in Dynamic Antenna Matching Circuit• Retransmission Mode Available• PC Programming (Optional)• LCD Backlight• Passed MIL-STD-810E for Harsh Field Environments• Passed MIL-STD-461C for EMI/EMC InteroperabiltyThis unit is compatible with the standard issue tacti-cal military radios like the PRC-77 and the SINC-GARS. It generates the standard 150Hz CTCSS sub-audible tone required for “squelch ON” operation. This allows the user full interoperability with existing units already in its inventory and also when operating alongside other services or other forces.(see specs on reverse side)*Names are the property of Motorola, Inc., Kenwood Communications, Inc., Icom America, and Tait, Inc. respectively.
