Radio Astronomy

During the April 2021 TARS meeting we were blessed to have Dr. Francisco Reyes – KK4AAV – University of Florida, Dept. of Astronomy talk on Radio Astronomy touching on the following topics:

  • Brief history of the Univ. of Florida Radio Observatory (UFRO) and the closing of the UFRO.
  • The observations of Jupiter’s decametric emission from UFRO and a station in Chile
  • Antennas and equipment used at UFRO and the station in Chile
  • Pulsar observations at UFRO and Chile and the antennas we used.
  • The Radio JOVE educational, public outreach and citizen science project
  • The Spectrograph User Group (SUG) network, equipment and the observations
  • The small antenna and spectrograph at Rosemary Hill observatory
  • Planning for the observations of the 2024 total solar eclipse in the US.

Introduction to 5G

TARS March 2021 Presentation: More and more spectrum availability to wireless service providers over the years has opened doors to enhanced communication standards and applications.  We will see increased throughput speeds, lower latency, and the ability to provide connection support to larger amounts of devices in small areas with increased bandwidth, flexibility in transmission, edge computing, and massive MIMO.  At the same time, the telecommunication industry’s infrastructure needs to be built out to be able to support the equipment density needed by the wireless service providers to fully achieve the leap from 4G to 5G. 

Crown Castle is one of the leaders in providing that network of communications infrastructure. John Hellmer, Senior RF Engineer from the Crown Castle Nation RF Engineering team, who will leverage over 10 years of RF Engineering testing, design, and optimization experience in the telecommunications industry in leading us through the evolution to 5G.
