It is a good time to value ourselves as humans and stop a little with the machines: Whatsap, Facebook, Twiter, Instagram, and even the FT8, RTTY, PSKL, JT65 etc.
• WiFi HF Antenna Switch

This article describes the design and construction of a remote WiFi Antenna Switch for HF that is an order of magnitude more economical than any wireless remote switch available today. It is limited in its power handling and frequency bandwidth, but I believe it is of great use for most of ham radio operators.

• Software for Digital modes. A Review
Added at 2014-06-17 08:02:34
There are a significant number of programs available to the Amateur Radio operator enabling the use of digital modes. Some are self contained, others form part of a suite of programs designed for general logging etc (DM780, WinWarbler) . Choice will be made largely on the basis of cost or personal preference based on ease of use and available features. My own preference, having spend some time using all the programs discussed, is for DM780 which I judge to be state of the art. If computer screen space is limited or a simpler interface is required, next on my list are the more ‘compact’ programs of Fldigi and MixW. MultiPSK offers more modes than any other but is definitely not for the beginner.
