Decoding Fire & Ambulance MDT data & hospital pages with a $10 SDR Radio

You don't need much to decode pager traffic - just a frugal Software Defined Radio and some free software. In this video I show how to decode the pages, particularly those used by Emergency Services (Fire & Ambulance / EMT).


These pages are often displayed on Mobile Data Terminals (MDTs).
I used a generic dongle in this video, but I recommend the frequency stabilised units (with TCXO) below :

NooElec SMART : https://amzn.to/2YKlh6p

RTL-SDR v3 : https://amzn.to/2NIGGGZ



I used an MCX to BNC adapter for the antenna : https://amzn.to/3omy3W7

However if you are using an RTL-SDR or NooElec SMART you'll need one of the SMA connectors, such as those in the kits below.
