ARLA/CLUSTER: App Android para alertas de propagação e aberturas em VHF desde o site the DXrobot.

[João Costa > CT1FBF]

EsSense (Free Beta)


Targeted (prefix-based) E-skip, TEP and Aurora alerts for the VHF ham
radio operator. From the DXrobot.

VHF DX spots, posted by radio amateurs to the worldwide DX cluster,
are constantly monitored and analysed by the gooddx.net server. When a
Sporadic E, TEP or Aurora opening is detected, the DXrobot will send
targeted push messages ONLY to users in relevant countries (countries
where the opening actually occurs). These users will then receive a
notification message (and optionally an alarm sound or vibration) on
their Android device. Tapping the notification icon will show a handy
overview of all countries (prefixes) currently active. The overview is
grouped by VHF band (2, 4 and 6 meters) and by propagation mode
(Es/TEP and Au).

The colour of notification icon indicates the status:
- grey: connected to DXrobot, but no current band activity - this is
the 'normal' state.
- yellow: lost connection to DXrobot - trying to reconnect every 5 mins
- red: Es, TEP or Aurora activity on any of the VHF bands

An additional yellow icon will appear when a newer version of EsSense
is available - tapping it will bring you to the Play Store for easy
updating to the latest version.

When an opening has occured, and you tap the screen then a new screen
will open showing the latest Sporadic E or Aurora spots on the
DXcluster. Wait 30 secs or tap the screen again to go back to the main
screen.

When EsSense is running, and you want to switch to another app, then
tap the HOME button. This will keep EsSense running in the background
so that it keeps listening for incoming alerts. If you tap the BACK
button instead, EsSense will close down completely and disconnect from
the server - so you won't receive any further updates.

Tip: On some devices the Wifi will be automatically switched off when
the device goes into sleep mode. The connection to the DXrobot server
will then be lost and no alerts will be received. To prevent this you
can install an app that keeps Wifi alive even when the device goes
into sleep. Several free apps are available for this on the market
(search for "keep wifi alive" or "keep wifi on")

The EsSense icons were made by my daughter Suze.

This is a beta test version and it is currently still free. However,
in a future version this may change depending on the volume of push
messages that are sent. I may then have to charge a small amount to
cover the cost for 3rd party push messaging services.

If you have any suggestions for further improvement, please email me
