What is a robot? Want to build a robot? Well, there are thousands of ideas already out there and hundreds of levels from the simplest non controlled robots to sophisticated space robots. What level are you at? Beginner, intermediate or advanced? An intermediate design would want to include remote control capabilities. The robot should perform useful work. The design should be written up in detail and include construction instructions. For additional information, visit:. Robot Rage - Miniclip.com. Student...

STAR LO
http://m0rjd.co.uk/LO.html
It has become apparent that constructors can and do end up with too little or a very distorted LO signal to the Magic Roundabout on 20m only. This is due to the inclusion in the Matrix of D405, which energises the 2nd (bandpass) filter on 20m, as well as on higher bands.

Now, back to the LO stuff! If you decide to use any ...
