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!
