Propfire now compatible with Firefox 3.X

Propfire, the Firefox radio/solar propagation data plugin that displays sunspot/prop data in the status bar, is now (finally) compatible with Firefox version 3.0.  I had sent a plea for help to the developer community as some major changes to the browser had led to a number of issues.  Trevor Hobson kindly offered to review my [...]

NOAA confirms beginning of Sunspot Cycle 24

January 4, 2008 was a big day in the world of HF radio propagation.  Sunspot #10,981 was declared to be the first of Solar Cycle #24.

Radio Propagation: "Are we there yet?"

As many of us are loading the car and shuttling kids to grandma’s house for Christmas festivities, we’re preparing ourselves for that infamous question… “Are we there yet?” 
HF ham radio enthusiasts are undoubtedly asking something similar of Sol. Hitting the bottom of the sunspot cycle trough between cycle 23 and cycle 24 has tested [...]

DXpedition map, Propagation Stats updated

For some strange reason (still unknown to me), the DXpedition Map and PropagationStats had stopped updating. There’s a lot of php code behind the scenes that I’ve used to create some of these tools and I guess I needed to convert to the new PHP version (5.X) to restore order. My ISP has warned that [...]

Propstats Flash Propagation Update Issue resolved!

Well it took a bit of creativity, but I was able to resolve the issue with Propstats. The scripts that run in the background should now require much less CPU by my webhost. I learned a few php tricks along the way that may be of use in the future.
PropagationStats should again be fully functional [...]

Propstats (PropagationStats via Flash) is offline

My ISP (icdsoft) has disabled the php script that drove Propstats. So, for the time being, the propagation statistics are not going to be displayed via Propstats. Apparently, so many folks were using it that the php was consuming a lot of CPU behind the scenes (every time a page was loaded that displayed propstats [...]

MobileLog 2 release, Propfire updates, and the tower…

After a long time without updates, I have finally found time to post. I had decided to not post to the blog until MobileLog 2 was released.
Well, in the past month, I have spent many hours updating MobileLog 2, Propfire and the website. In December I had made a week long trip to Manila. 11 [...]

Firefox 2.0 RC3 - Propfire

I installed the update for Firefox 2.0 release candidate 3 today and it seems to work well with my Propfire extension (which displays radio propagation information in your Firefox status bar). Solar index information, a k-index chart, etc, all seem to work.
If anyone finds an issue with Propfire on Firefox 2.0 please let me [...]
