IonoProbe 1.4

Space weather monitor for Amateur Radio

Monitors space weather indices
and helps you learn what those indices mean

Integrates with DX Atlas and Ham CAP

"You've provided a great way to monitor solar activity, and an even better incentive to learn what it all means!"

Howard, W6HN

"The new program works really well. I have not noticed any problems. The updates look accurate. It's interesting to look at the past conditions and try to correlate that to band conditions."

Mike, NR5O

"Very nice program. I can find no flaws and use it constantly. Sometimes its predictive accuracy is a little scary. I was on 20M, received a storm alert and within seconds the band died."

Joe, N6FPJ


IonoProbe is a 32-bit Windows application that lives in the System Tray and monitors the space weather parameters essential for HF radio. The list of parameters includes SSN/SFI, Ap/Kp, X-ray/Proton flux, and Auroral activity. IonoProbe downloads near-real time satellite and ground station data, stores information for future use and displays it in a user-friendly way.

Time-critical parameters, such as X-ray flux, proton flux and auroral index, are updated every 15 minutes. An alarm can be set up to notify you of a storm within a few minutes after its start.
