D-Star in Dixie

Okay, this is not strictly SDR, but this site is dedicated to discussing the latest and interesting technologies  that are being used in Amateur Radio. Like a lot of hams, I had sort of dismissed D-Star as an expensive niche product. Last field day, a ham friend on mine mentioned that a new D-Star repeater had been brought up in the area. After the discussion, I thought I would take a second look at D-Star. I was surprised to see  so many D-Star repeaters had sprang up in Georgia (about 26 and still growing).  As a matter of fact, D-Star repeaters are popping up like weeds in the Southeast. Other areas of the country are also seeing growth in D-Star repeaters. I was also quite amazed to see that there were about 18,000 registered D-Star users worldwide . If you want to see the the statistics of how quickly D-Star is growing, take a look at the D-StarUsers.org Watch D-Star Grow page.

Flex 1500

I am sure that you have read all the great reviews for this little radio, but I thought I would throw in my 2 cents worth. This is one of the most FUN little QRP radios that I have had the pleasure of owning over the past years. The audio quality is extremely good and is a real pleasure to listen to. I have had a great deal of difficulty in the past enjoying HF radio while living in a high RF environment and restricted to a very crappy attic dipole. The Flex doesn’t seem to mind any of this.  With the various noise reduction tools and filters, it makes HF a real pleasure to use. The 5 watts output seems to be plenty for most applications. I have had no trouble getting heard around the world on WSPR. Overall, this is an excellent little radio for the money!…
