CHANGES TO CLEAN SCOOP CERTIFICATE REQUIREMENTS
We have had horrible cooperation from the weather for the first 3 events and our on the air time has been limited so the club decided to change the qualification for the certificate. Now you only need to QSL 5 of 7 of the Special Events to get the clean scoop certificate !!
Good Luck and 73 from SEKARC

Shape Shifting For Antennas

Here is an interesting video! Normally, when you want to adjust the resonant frequency of an antenna, you add electronic components like inductors to the circuit. But you can only go so far with that approach; at some point you’ll have to change the physical length of the antenna. That’s fine if you’re designing something, but impractical to do on the fly—until now. Researchers at North Carolina State University in Raleigh used liquid metal to construct an antenna that lengthens or shortens on electronic command.
