I have just uploaded an updated version to Google Play.

See https://play.google.com/store/apps/details?id=xxx.wspr.g4swy

In this version I have re-engineered the download code to improve stability and memory management.

The enhanced features are :-

I am trying to write a false spot detector/suppressor for my WSPR World Watch Android app.

Here is a set of obviously bad decodes :- (See attached png.)

I took world map screen shots every 4 minutes on 600, 160, 80 and 40 Meters on 20th March, the day of the eclipse.

I turned the bitmaps into short videos of the full 24 hours and published them on YouTube.

I have just uploaded a new version to Google Play at https://play.google.com/store/apps/details?id=xxx.wspr.g4swy

The main changes since the previous version are :-
Screen keep alive.
Checking of device date and time.
The app now refreshes one band every ten minutes and whispers something like 'Ten meters open to Bravo Lima'.

The new version 2.0.3 is now published at : -


The changes and enhancements in release v2.0.3 are :-

Fix for crashing menu in Lollipop latest version 5.0.2. This fix may not work with earlier Lollipop releases.

Improved user interface with fixes for out-of-memory and disappearing menu.
Plot of aurora.
Space weather display.

Version 1.0.0 of this app is now published on the Google Play Store.

Search there with 'WSPR'

This app plots real-time transmission paths on a world map which may be centered either on the Atlantic or the Pacific. It includes a background display of the 'greyline' or terminator.

Paths for a single station may optionally be displayed with callsigns.

It is highly recommended that you read the FAQ to get the full benefit of the features in this app.

Very many thanks to the testers of this app who have given me much valuable advice.

This is an Android app that depicts current band propagation conditions as determined from WSPR spot reports.

I am about to publish this on Google Play but would like to test it on a few more devices.

If anybody would like to help me with this I would be enormously grateful.

Email me at g4swy@yahoo.com and I will send you an APK file to install.
