Here are my tips for making TrunkPcr1k working correctly. 1. Use the "Packet" output on the PCR-1000, not the speaker out. 2. Set the polarity to be "Reverse polarity" under the Trunk menu. 3. Create a directory named "banks" in the directory that you installed the TrunkPcr1K program into. After doing this the program has been working great.
