Introduction

Here, you will find a list of stations that emit signals towards the ionosphere. Many different types of these transmitters exist, which differ in sweep speed, period, some emit digital signals, other just a carrier, etc. The tables represent a recopilation of many sources and we will try to maintain this list checked (at least for the stations which we can control). Peter Martinez, G3PLX, is actually in charge of the maintenance of the table.

Any report will be appreciated. To contact Peter, or the other members of the chirp gang, please contact the mailing list

In the left column of this page, you can ask to order the table by different criteria (geographical location, chirptime, sweep speed, period and by number). It's also possible to ask for a special file in a format which is easily imported in most spreadsheet and database programs (CSV - comma separated values).
