That second scanner would have a dedicated computer (or, as the nerds would assert, you could also use a virtual machine on one physical device) which decoded the digital voice.
One scanner and computer would track the control channel and then send a signal to a second scanner that would follow calls around on EDACS. Prior to GRE’s releasing the updated firmware for PSR-800, doing this meant using two scanners and two computers. You also have to track the system’s control channel to follow the radio calls as they jump around to different frequencies. You can read all about that here:īecause Honolulu County uses a trunked system (EDACS) rather than conventional frequencies, scanning means more than decoding digital voice. It can then be decoded with a program called Digital Speech Decoder. The discriminator tap allows it to pump-via a regular speaker audio cable-raw and unbuffered digital speech into your sound card. It had a built in discriminator tap, and was the first of its kind when it hit the markets this year. You see, the PSR-800 was revolutionary to begin with.

Even though the scanner alone won’t bring you HPD’s patrol channels and Honolulu Fire’s dispatch and tacticals, adding a computer equipped with Microsoft Windows or a Linux distribution will enable you to decode ProVoice and listen in as our local heroes battle fires and fight crime. You won’t hear anything, though save for that, well, digital sound that is ProVoice.
#GRECOM PSR 800 FIRMWARE UPDATE#
Scanner manufacturer GRE released a firmware update to its PSR-800 digital trunking scanner that allows it to follow EDACS talkgroups that are digitally voiced. We scanning enthusiasts have to be proactive about staving off-and eventually killing-our worst enemy: encryption.įirst, let’s cover the big development that happened late last month. But before we celebrate, we have to acknowledge what this really means. Scanning HPD, HFD, and Honolulu County’s other public safety agencies that use MACOM’s proprietary ProVoice modulation for their communications just got a whole lot easier. The “good old days” of radio monitoring are back, and hopefully for good
