KB9AT.COM is the internet portal for support of the fastest growing segment of the Amateur Radio hobby: On-Air operations using Digital Modes. It's also where information about the Digital Frontier Foundation can be found.

From this home page, you can access four of the most popular downloads for Digital Mode software, reach two excellent High Frequency Propagation Prediction sites - including one that is exclusively dedicated to propagation using Digital Modes, and  be linked to two proprietary weather sites created by kb9at. The weather sites are very useful to hams participating in NOAA's Skywarn program, those users of troposphere ducting propagation, and hams who are also pilots.  Finally, there's a gateway to allow purchase of two types of Amateur Radio certificates developed by kb9at. (The sale of certificates helps offset the server and domain costs associated with this website.)

If you're new to Digital, you can find a short primer on the Digital Modes page of  ARRL's website. For a more in-depth look at this segment of our hobby, I suggest you purchase Steve Ford's (WB8IMY) excellent book  from  Universal Radio. The book can be purchased by following this link: Get On The Air With HF Digital.  Steve's book will tell you everything you need to know concerning what modes are available, what software is needed, Digital Mode specific frequency information, and computer/transceiver interfacing.

Please bookmark and access it often.  And look for additional useful information as time goes on.

Thank you for visiting!
