DXHeat.com is online

DXHeat Logo App Rounded

Over last 8 month I was digging deep into Web Development. The result went yesterday public – DXHeat.com. Instead of building just “another” Web DX Cluster, I tried to build something innovative with new, unique features. Best is to check it out by yourself!

Within the first 48 hours the site received more than 3000 visitors. DXHeat.com was featured on a couple of blogs and I was retweeted almost a 100 times! So I’m very happy how well DXHeat.com was received in the Amateur Radio community. In the last minute before the public launch I added an easy accessible feedback form. I’m glad I did! I received more than 20 comments with valuable feedback – reporting small bugs and requesting new features.

So let me quote the most important (unique) features of DXHeat.com:

  • Graphical representation of band activity vs continents
  • Integration with WebSDR
  • DX Analytics with plenty of diagrams for all callsigns spotted since 2001
  • Flexible, but easy to use filters
  • Responsive Design – looks good on phone, tables and Desktops
  • Spots are pushed in realtime into the browser


This project would have never been possible without the contribution of:

  4. I was never in Gibraltar but two hams missed the last dot of Z6!

    This feedback failed at DXHeat.com site with server failing to send email under my Win7 and firefox.

  6. Is it possible to adjust the sort for frequencies within a band? For instance, I am a general and have limited band access. It would be great if I only say frequencies within the general bands!
