DSP APP Firmware Version U1.4 provides the following enhancement to your PRO-96/2096 Digital Trunking Scanner:
Improved digital decoding:
After upgrading to DSP Application firmware version 1.3 (DSP-APP 1.3), some users reported increased instances of the scanner failing to decode the beginning of digital transmissions on certain systems. DSP-APP 1.4 improves the performance of initial digital voice decoding and should result in fewer instances of undecoded digital noise at the beginning of transmissions. Under certain circumstances, such as when weak or distorted signals are present, the scanner may occasionally fail to decode the beginning of a digital transmission even after upgrading to DSP-APP 1.4.
If a radio consistently fails to reliably decode digital transmissions, users are advised to reposition the radio, utilize antennas designed for the specific band being monitored, such as the Radio Shack 20-283 800 MHz BNC antenna, or take other steps to improve the quality of the received signals.
