Well, I was going to start using ROS on UHF and maybe occasionally on HF and let the K3UK decision and other chips fall where they might.
However, the ARRL just released a statement indicating that the author of the software has lied to the amateur community about the legal status of his program in the USA. Read this if you care: http://www.arrl.org/news/stories/2010/03/04/11377/?nc=1 In view of the foregoing, I will not use ROS in my station. Nor will I recommend that any other ham use it. I will stop short of suggesting that anyone NOT use it (at least on UHF where it is legal here in the USA). 73 de Dave, NF2G
