UTA Campus

    Thanks to Dave Davis and Crew at UTA and to the Chapter 67 Volunteers

    The UTA Nedderman Hall was a perfect venue for the Ennes DFW Workshop but Dave Davis and his crew - Gary and Joe - were on top of every detail to make the entire day go smoothly.

    Dave arrived before 6am and stayed until everyone was gone and everything was cleaned up. He attended planning meetings and made invaluable suggestions for the events success.

    Dave and the crew provided help to speakers and sponsors all day long making sure all the A/V systems ran flawlessly, tables and chairs were where they needed to be and countless other "little things" that make an event like this work.

    Thanks to Buddy Brown for picking up the ice at 6 in the morning, bringing it in and wrangling it thru the day, along with the food tables, so that we never ran out of either.

    And thanks to Bob Butler and Tom Scheussler from Chapter 67 for helping with the setup, signage and teardown.

    Ennes DFW Workshop was a Success

    63 people registered for the Ennes DFW Workshop at UTA in Arlington and nearly everyone attended in spite of a continuous sometimes blinding rainstorn from about 3am to 2pm in the area. From start to finish, this event provided excellent food and a full day of learning.

    The speakers were great and topics were timely. Students attended the first ever Antennas 101 and Wiring 101 sessions. And the final 2 hours saw another first for the workshops - Wayne Pecena provided the basics of TCP/IP for Broadcast Engineers. Full coverage would normally take weeks to complete but Wayne provided a thorough introduction that Chapter 67 will be following up through the coming months with much more on TCP/IP.

    Breakfast and Lunch were catered by Corner Bakery. RF Specialties of Texas sponsored Breakfast and Continental Electronics provided Lunch. And RF Specialties, ProAudio.com and Orban had informative exhibits.

    Student Classes and TCP/IP – both “Firsts” for the Ennes Workshops

    Wiring 101 or How Cable Works taught by Steve Lampen, CBRE and Multimedia Technology Manager at Belden. Steve had an extensive career in radio broadcast engineering and installation, film production, and electronic distribution. He holds an FCC Lifetime General License and is an SBE Certified Radio Broadcast Engineer.

    Using pictures and stories for this primer on wire and cable - including multiconductor, twisted pairs and coaxial cable - Steve illustrated where they came from, why they were invented, and how they work.

    Steve includes an overview of analog and digital signals, frequency and wavelength, resistance, capacitance, inductance, and the result of those three parameters, impedance. And a refresher on unbalanced and balanced lines, return loss, and skin effect.

    Antennas 101 by Bob Surette from Shively Labs - discussed some of the changes over the years when it comes to FM RF transmission systems and how you need a good understanding of basic filter and antenna theory.

    This presentation was designed to explain how energy is radiated from a single source and how multiple sources can be connected together to form a simple antenna array.
