TWO Frequencies Monitored:
(1)
Location: Waltham, MA
Frequency/Modulation: 470.5125 MHz (Conventional P25 Phase 1)
Alpha Tag: "Waltham PD-1"
Description: "Police F1 Operations"
(2)
Location: Waltham, MA
Frequency/Modulation: 470.1125 MHz (Conventional NFM)
Alpha Tag: "Waltham FD1"
Description: "Fire Ch 1 Operations" (analog only)
FYI - I would add the secondary channels for both but the frequencies used are too different - I would literally need THREE separate SDR dongles and a signal splitter. They don't appear to get used often anyways.
HARDWARE:
Raspberry Pi 4 with a "Nooelec NESDR SMArTee XTR SDR" connected to a Tram scanner antenna stuck to a grounded piece of sheet metal.
Yep.
SOFTWARE:
Largely followed this guide.
trunk-recorder recompiled to use the older p25 decoder
