The Los Angeles Police Department is continuing an intensive avionics upgrade campaign for its air operation with selection of an airborne radio package from Toronto-based Technisonic Industries (Booth No. 2356).

The buy includes a TSOed audio system with capability to support seven transceivers in simulcast operation. The A711L system can be transferred to public address operation, leaving radio frequency settings undisturbed, and it remains audible in “the worst noise environments,” according to Technisonic.

A companion multi-band radio system, the TDFM-7300, also on display at Technisonic’s booth, can accommodate up to four digital P25-compliant transceivers. In addition, an analog VHF 30-50 MHz module is standard. The system can also provide frequency bands including VHF 136-174 MHz, UHF 380-470 MHz, UHF 450-520 MHz and both the 700 MHz and 800 MHz band modules (764-870 MHz).
