If you are an ARRL or W5YI Volunteer Examiner attending this year's symposium, please contact me off the AMSAT-BB. We have the opportunity to test a foreign visitor. I'd like to arrange a test session that will fit into the symposium schedule. Very likely it would be early in the morning of Saturday or Sunday. Thank you, Clayton W5PFG

Yeah, this is a requirement that has vexed designers of complex electrical systems for years. One solution, generally meeting this requirement, is to go ahead an utilize separate ground rods and tie the rods together with a (large) grounding cable--usually pvc insulated cable for corrosion protection. In industrial installations these connections are often made so they can be disconnected in the event of differential currents flowing and causing problems with communication/signal systems. Much like K8BL's recommendations, I too have used #10 AWG for the ground from the rotor/mast to the ground rod, and hoped and prayed the lightning liked it (if ever needed). This is especially important for a non-earthed installation like a tripod on a roof. I have been fortunate to never having to find out... 73, Jerry, M0GOE

Lightning protection
by David Carr 16 Oct '13

Hi group, I have a new wooden outbuilding and am thinking of putting a rotator on the roof. What are the best practices for lightning protection for a setup like this? I'm not as worried about the equipment as I am the building catching on fire. There are some things inside that are very important to me. Thanks for the help, David KD5QGR

FUNcube-1 has arrived in Russia
by Graham Shirville 16 Oct '13

16 Oct '13

The exciting news is that FUNcube-1 CubeSat is now en-route to the Yasny launch site. It was flown on a special flight from Rotterdam yesterday and it cleared through Russian customs this morning. Well before the launch date, Dashboard software, to decode and display the telemetry, will be made available for download, this will function on any windows pc or laptop using either a Dongle or a 2 metre SSB capable receiver. Additionally a set of pre-launch keps will also be distributed. This launch will carry more than ten spacecraft using the amateur satellite service and one of them will, itself, later deploy up to nine CubeSats and PocketCubes so there should be plenty of new signals to listen for after this launch More info about FUNcube and some pictures can be seen here www.funcube.org.uk best 73 Graham G3VZV

The best practice varies from region to region. Omission of a single factor can negate any insurance claims, so the best practice is to hire the services of a licensed electrician who would be familiar with the local electrical code. The insurance company should be able to provide references.
