Basic Info:
My feed was approved and listed on 2025-01-19 and I started streaming on 2025-01-21. During the first few days I had to change out a bad cable as well as refine my gain structure to eliminate a significant amount of unacceptable noise. Currently the noise floor is as good as it can be until I implement a noise gate. I'm putting together a simple hardware noise gate circuit along with audio bandpass filtering, 10-band graphic EQ, and compressor to shape the audio perfectly. For better reception I plan to use an outdoor mounted tuned Yagi antenna

Mission Statement:
I wanted this feed up and running ASAP and so I used the extra parts and devices I already had on hand. Setting it up as a tradition scanner sourced audio stream was quick easy tried and true. My next step, in addition to the aforementioned audio and antenna upgrades, is to make an SDR call-ingest platform version.

Current Setup:

- Radio Shack Pro-163 Scanner
- Raspberry Pi 3b
- Broadcastify's image v3.01
- Sabrent mini USB audio adapter 
- Antenna: Indoor mounted Larsen Tri-Band NMO
