The May meeting of Chapter 18 of the Society of Broadcast Engineers was held at the fourth floor conference room of Greater Philadelphia Radio Group, One Bala Plaza, Bala Cynwyd, PA with 11 members and guests in attendance.


Mark Humphrey, Chapter 18 Chair, opened the meeting by discussing awards, new certification statuses, national elections and the SBE's new software tool--the SBE Toolbox. He also mentioned that he is, as of 31 May, no longer with Radio One--Philadelphia and is the owner of his new consulting firm, XY Mark. Mike DePolo has taken his place at Radio One.


Mark also mentioned that Ben Hill, of WIP Radio (Infinity Broadcasting) is sponsoring the "SBEBq" on 28th June 2005 at the WIP transmitter site on Creek Road (off of Route 42) in Bellmawr, Camden County, New Jersey. Directions will be provided. We need volunteers for the event.


Larry will discussed the FCC issues stating that the FCC has a DTV rollout time set and also discussed the new 222G Tower Standard that is awaiting ANSI approval. The standard has created new categories and will affect many, especially those in high wind areas. Most of the towers in this area are C and D standard. Accidents led to the change of standards. Though safer, the new standard will drive up costs.


Thanks go to Larry Paulausky, John Arndt and Angela Lofton and to Dave Hultsman of Continental Electronics for hosting the meeting and sponsoring the pizza dinner (which came from Allegro Pizza) respectively.




Dave Hultsman of Continental Electronics was the presenter. His presentation was entitled Expect The Unexpected--IBOC Concepts, System Topologies and Continental Electronics Systems with the following subtopics presented:


  • FM Hybrid Wars--mode MP1
  • All Digital FM Waveform
  • Extended Waveform--MP2, 3 and 11
  • All Digital Waveform--general
  • FM Implementation Option--most complex to simplest
  • Four Methods for IBOC implementation--
  • High-level Combined System--RF isolator, multi-station combiner and IBOC high level
  • Mid-Level Combined IBOC FM System
