Simple APCO P25 Phase 1 Decoder Plugin Released for SDR#

Vasili, author of several SDR# plugins has recently released a new APCO P25 plugin for SDR#. The plugin is easy to use, simply tune to a P25 voice signal, and it will automatically decode it into voice audio assuming that the signal is not encrypted. If the P25 signal is encrypted, you will hear garbled unintelligible voice. The plugin does not support trunking or any advanced talk group filtering features that you might find with DSD+, Unitrunker, SDR Trunk etc.

To install the plugin, simply download the zip file from rtl-sdr.ru and extra the .dll's into the SDR# folder. Then copy the text in magicline.txt file into the plugins.xml file inside the SDR# folder. The plugin should work with any SDR supported by SDR#, including the RTL-SDR.

    When I use the plug in sdr# shuts down when it gets a p25 signal. It will play a split second of audio then just shuts off completely.

    When it says to copy the magicline.txt into the plugins.xml folder, which folder is that? Im showing Plugin Repositories, plugins-list.

      Let me change one word in the article above, maybe that will help you understand:
      copy the text >>>inside<<< magicline.txt file into the plugins.xml file inside the SDR# folder

    Rapidly tested with my personal P25Phase1 radio today, and seems to be working fine !
    (Good intelligible voice on Clear mode, and [of course] garbled mess when encrypted)

    An user on Vasili’s website reported SDR# crashing at plugin launch, no problem for me on SDR# v1732, but your milleage may vary…
