(RF) technologies, its important to be familiar with the various wireless systems. This starts with understanding the different types of radio waves and their characteristics. In this module we introduce you to units of frequency, frequency bands, propagation and how radio waves travel, environmental effects on propagation, and simplex and duplex systems.

SK6RUD QRPP Beacon with half a watt from Sweden using a Michigan Mighty Mite Transmitter. Normally an excellent signal into Scotland but propagation not the best when this recording was done. Radio used for receive was an ICOM IC-7000 with the 250Hz filter switched in and a Doublet. www.radiorud.se for radio reports.

talked with Robo and we are thinking that Boris optical equipment is ready for contact up tu 50km. So we are looking forward for the longer distances. After the contacts with Boris we tried once again contact with our friends in Vienna. Propagation is not ideal, but it is changing in time, so we decided to stay and try it. Our last attempt to Vienna was not successful. We are pointing Robos Xenon strobe to Vienna but our friends can not see anything. We are trying to point my high powerlaser ...
