In the spring of 2017 Flex Radio announced an upgraded version of their 6000 line of SDR based transceivers. These models were labeled the 6400,6600,6400M, and the 6600M. In a nutshell, the 6400 series is an upgrade of the dual slice receiver 6300 and the 6600 is an upgrade of the four slice receiver 6500. The M series adds an 8 inch color touch screen display plus knobs and buttons for “no computer needed” operation. The chassis has gotten larger on the new 6000 series also. With exception of the size change and the builtin displays most of the changes are internal such as better filtering. The new 6000 series also come with the latest version SmartSDR which features an improved remote over internet component called SmartLink.

New Forum for Ham Radio Science

As of today, HRS has decommissioned the old forum. We were just getting too many spammers. The new forum will allow us a better opportunity to help reduce some of the spam. Unfortunately, we were not able to move the user database or the old posts to the new forum. If you were a member of the old forum, you will need to sign up again. The old forum will be available for a little while longer, but we will eventually remove it. Let me encourage you to try to post your comments and questions in the forum. I have noticed that the comment sections of some of the articles are getting a little unwieldy. You will probably stand a better chance of getting an answer to your questions, if you post them in the forum.

Thanks for your patience!
