Thank you for the lecture on radio waves.
Thank you for your reply..
You are certainly entitled to your opinion. Nothing will change. About had it with naysayers on instructables. One of the reasons I have not renewed my membership. By the way, I started with Slackware back in the 1990's.
Personally I thought the policy of instructables was not to be nasty. Just because you do not see it does not mean it is not valid. Sure hope no one poops on your instructables.
