About HamAlert

What is HamAlert?

HamAlert is a system that allows you to get notifications when a desired station appears on the DX cluster, the Reverse Beacon Network, SOTAwatch, or PSK Reporter. No need to keep checking these resources manually if you're looking for a certain callsign, DXCC, CQ zone, IOTA island, SOTA summit or WWFF reference.

You can receive alerts via Email, Push notification, SMS or URL GET/POST. You can also filter spots by various criteria, including:

Furthermore, you can set limits on the number of alerts in a certain time period so you don't receive duplicate spots, but are still notified if for example the station changes to another frequency.

Push notifications

A basic HamAlert app is available on Google Play and the App Store. It can receive push notifications for free, and shows spots from the past 24 hours (up to 100 recent spots that were matched by a trigger that has the "App" action enabled).

You can also get push notifications sent to Threema.

SMS notifications

Reliably sending SMS from computers to mobiles is not free, as you probably know. To avoid having to charge HamAlert users directly for the SMS that they use, HamAlert instead supports the Clockwork SMS gateway. If you want to receive SMS notifications, sign up for an account at Clockwork SMS, get some credit on it (you can get free credit for testing), and paste your Clockwork API key (a long hexadecimal string) on the Destinations page. HamAlert will then use your Clockwork account to send you SMS. Make sure you keep enough credit on your Clockwork account to avoid missing SMS notifications.

At this time, only the Clockwork SMS gateway is supported. It was chosen because it offers an easy interface for end-users and developers, and has reasonable pricing. If there is sufficient demand, other SMS gateways may be added in the future.

DXCC lookups

Accurately determining the DXCC and CQ zone of a particular callsign is no easy feat. Luckily, the team at Club Log are experts in this and provide an API that HamAlert uses. Thank you, Club Log, for making this API available!

Digimode spots

Digimode spots (with the “PSK reporter” source) are obtained from pskreporter.info. Thanks to Philip Gladstone for running the system and letting HamAlert access its data!
