From Frustration to Innovation

Built by a broadcaster, for broadcasters.

I'm Rob Johnstone, and I've spent years as Chief Engineer for multiple radio stations in the Poconos while also running Stroud Media, the fiber ISP my wife Jill and I founded in 2020.

Every broadcast engineer knows the pain: transmitter sites go down at 2 AM, traditional monitoring equipment costs $5,000–10,000 per site, and most solutions are overengineered for what we actually need.

I started tinkering with RTL-SDR dongles and Raspberry Pis to monitor our stations' off-air signals. What began as a weekend project turned into RadioMon — a complete FM monitoring system for under $500 that does everything the expensive boxes do.

Then came everything else.

Once RadioMon worked, the ideas kept coming. I/OMon for transmitter telemetry. AlertMon Pro for EAS compliance — because every engineer dreads that FCC inspection where you can't prove your ENDEC forwarded alerts. TempMon for the ice cream shop owner who lost a freezer full of product overnight. GPS TimeMon because every broadcast facility needs accurate time and NTP servers shouldn't cost thousands.

BroadWatch ties it all together — a cloud platform where you can see every site, every sensor, every alert in one dashboard.

Why we're different.

We're not a big corporation. Every unit is assembled, configured, and tested right here in Stroudsburg, PA. When you call support, you're talking to the person who designed it and built it. Our ISP experience means we understand networking at a deep level — BGP, OSPF, VPN tunnels, MikroTik, the works.

It's affordable, it's turnkey, and it speaks SNMP natively so it works with tools you already use. No proprietary software. No recurring fees unless you want our cloud service. Just solid, reliable monitoring.
