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 filter spots by various criteria, including:
| DXCC (actual and callsign home DXCC) | Continent |
| Callsign | Band |
| IOTA group reference | Mode |
| SOTA summit reference | Time and days of the week |
| WWFF division/reference | Source |
| CQ zone | Spotter callsign and DXCC |
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.
A WebSDR is a Software-Defined Radio receiver connected to the internet, allowing many listeners to listen and tune it simultaneously. SDR technology makes it possible that all listeners tune independently, and thus listen to different signals; this is in contrast to the many classical receivers that are already available via the internet.
Most WebSDR’s work the same way and incorporate the same options and features. To learn more about how to use WebSDR, see this link: http://www.vra.be/teksten/SDR/Guide-to-using-WebSDR-v20161031.pdf

The Reverse Beacon Network (RBN) is a revolutionary new idea. Rather than scanning the HF bands looking for beacons to determine propagation, the RBN uses a network of volunteer stations listening on the bands and reporting what stations they hear, when and how well.
To use the RBN, simply call CQ (phone, cw, or digital) and the RBN force of amateur listeners will report where propagation is best from your location and how well your signal was heard.
Pretty ingenious idea!
VOACAP is free, professional, high-frequency (HF) propagation prediction software from NTIA/ITS, originally developed for Voice of America (VOA). Using the many graphs and data points the ham operator can now know, in advance, the probability of making contacts in a specific part of the world.
Originally designed to help assess the range of VOA transmissions, this utility is a must-use for those dx hunters looking for elusive contact points.
Just as the website name implies, this resource is a massive list of DX being reported from all around the world. Over 30,000 operators use the system regularly, providing great coverage for DX spots. If you are looking for specific call prefixes or areas on the globe to work, this is a great place to start.
(NOTE: The language of the cluster is Spanish. I haven’t yet figured out if they also offer an English equivalent. If you figure it out, drop me a note at Webmaster@PerryCountyARC.org)
This isn’t so much a ham radio tool as it is an SQL monitoring service for finding, identifying and listening to “number stations.” What is a number station? A numbers station is a shortwave radio station characterized by broadcasts of formatted numbers. These, at times elusive transmitters, are believed to be passing sensitive data by use of number codes and ciphers to intelligence officers operating in foreign countries. Some real spy vs. spy communications!
Here is a good web based page for DX spotting: https://dxheat.com
It has a lot of good info including a band activity grid.
Hi, wondering if you have a ELF/EMF low frequency electromagnet field meter or know someone that does? I have a micro chip planted in me. It is a two way communication, gps, and knows what I’m saying and hearing. Insurance will not pay for this. I have dealt with this 3+ yrs. I know the persons who done this. I need help! Not as simple as a dog or cat chip. Thank you in advance for any response or help.
