IonoProbe 1.41
has been discontinued

because NOAA no longer provides some of the data feeds that were used by IonoProbe.

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.
