Expanded Frequency for RELM’s BK Radio P-25 Portable

Expanded Band Now Serves 136-174 MHz

WEST MELBOURNE, Fla, and MONTREAL, August 10, 2004 – The frequency range of the BK Radio flagship DPH digital portable radio from RELM Wireless (OTC Bulletin Board: RELM - News) has been expanded to 136-174 MHz from its previous range of 147-174 MHz.

“This is a frequency band often assigned to and favored by high-specification radio users in public safety and homeland security agencies, as well as military units,” commented RELM Wireless President and CEO David P. Storey. “This opens additional markets to RELM, and in turn we believe that our world-class RELM BK Radio digital DPH is the best choice in that market, offering practical advantages at much lower cost.”

Among the practical advantages of the DPH cited by Storey are:

·

Easier to use (especially in emergencies) – streamlined user interface

·

Exceptional audio quality – easier to hear and be heard

·

Longer life between battery charges or disposable battery changes

“This expanded band enhances our capacity to handle customer requirements where our digital radios are most needed and wanted,” Storey continued. “For certain public safety, homeland security and military users, this is their operating frequency band, and we believe RELM Wireless has the best-engineered solution for what they need.”

The RELM BK Radio digital DPH radio meets or exceeds the specifications for compliance with the APCO Project 25 standard for public safety users. This expanded band introduction is being announced during the 70th Annual Conference and Exposition of APCO International (Association of Public-Safety Communications Officials - International) held in Montreal on August 9 through August 11, 2004.
