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.
Also, check your internal antenna connection. On the PSR-500 there have been reports of a screw loose inside that connects the antenna to the " motherboard?"
