WSPR it's a protocol, developed by K1JT Joe, designed for probing potential propagation paths with low power transmissions. Normal transmissions carry a station callsign, maidenhead grid locator, and transmitter power in dBm.

This App, used in combination with an hamradio transmitter, allow you to send a signal that, if received by someone, will be reported on wsprnet.org.

This is also great tool for checking your antenna system or comparing two radio,

Inside the App you will also find the connection schema, under "Help" menu, for radio with VOX and PTT!

Exactly what I was looking for

This app is exactly what I need: to be able to do wspr beacon antenna testing using my phone and portable rig. Easy set up and operation. I run it and hold the rig mic up to the phone. Nice product.

Exactly 1/2 of what I need

The transmitter side works well. It would be really helpful if it could also decode.


Maybe Tx, Maybe No Tx

It transmits at random times.

The fatal flaw in this program is that it does not warn you when it plans to transmit next.

I want to be in charge of my station and not have this app be the control operator who does not communicate with me.
