RF Safety for Amateur Radio Operators

Speaker: Bob Olsen, WA7WWP

Abstract:
Bob will cover the FCC requirements for determining which amateur stations need to be evaluated for RF exposure and if needed how an evaluation can be conducted.

Bob will also discuss and demonstrate RF Exposure Calculators available to amateurs and the theory behind them. Bob will emphasize some of the difficulties and point out that most calculations overpredict the exposure. He will discuss the RF Exposure standards used by the FCC and add some information about the origin of these standards.

About our speaker:
Robert G. Olsen received his B.S. degree in electrical engineering from Rutgers University 1968 and his M.S. and Ph.D. degrees in electrical engineering from the University of Colorado, Boulder, CO in 1970 and 1974, respectively.

Bob has been a member of the electrical engineering faculty at Washington State University since 1973 and holds the rank of Emeritus Professor. During his tenure at WSU, he has been an NSF Faculty Fellow at GTE Laboratories in Waltham, MA, a visiting scientist at ABB Corporate Research in Västerås, Sweden and at the Electric Power Research Institute (EPRI) in Palo Alto, CA ,and a Visiting Professor at the Technical University of Denmark.

Bob’s research interests span all aspects of electromagnetics issues in power transmission. He has approximately 100 publications in refereed journals and approximately 150 conference publications/presentations. He is also one of the authors of the AC Transmission Line Reference Book – 200 kV and Above, which is published by the Electric Power Research Institute (EPRI), and the author of the recently published two-volume book, High Voltage Overhead Transmission Line Electromagnetics.

He is a Fellow of the IEEE, an Honorary Life member of the IEEE Electromagnetic Compatibility Society, and has served as chair of the IEEE Power Engineering Society AC Fields and Corona Effects Working Groups. In addition, he is past Associate Editor of the IEEE Transactions on Electromagnetic Compatibility and Radio Science.

Software Defined Radio

Speaker: Mike Walker, VA3MW

Abstract:
Mike will show how today’s HF radio is not only better than yesterday’s super-het radio, but how you get more performance for your dollar. He also will talk about how the new radios ‘scale’ toward the future and not grow old the day you buy it.

About our speaker:
Mike Walker has been an active amateur radio operator since 1974, and loving every minute of it. His interests are repeaters, HF, HF contesting, satellites, and tinkering with EME digital modes and 10 GHz microwave. In addition to being a general aviation pilot, he loves HF station integration and remote HF operation. He currently represents FlexRadio Systems with the Marketing and Education team. He is very well versed in the FlexRadio technology. Technology is truly his hobby.

Modulation: Sound Card Digital Modes on HF SSB

Speaker: Barry Feierman, K3EUI

Abstract:

Sound card modes: How they look and sound. What can a sound card do that a human voice cannot do in terms of passing information on a radio signal?

Barry will discuss the concept of modulating a 145 MHz RF wave with a 1.5 kHz sound wave. He will transmit a signal first on AM, then on SSB, and finally on FM. Using an SDRPlay receiver with a spectrum analyzer set to 145 MHz, he will display the RF spectrum of these signals.

Barry will demonstrate a variety of popular sound card digital modes, including CW, PSK31, RTTY, Olivia, MFSK, and THOR. Using an SSB transmitter, he will share with NY ops who have an 80m SSB radio and antenna what these modes sound like (assuming propagation from Philly to Schenectady on 80m NVIS).

He will use the internet sound as a backup. Popular apps like FLDIGI and Winlink use these sounds created in a sound card to produce “modes” that transfer information much faster than is possible with a human voice on a phone link. Rates as fast as thousands of bits per second on HF SSB is possible using modern sound cards (getting beyond the present 300 baud speed limit of one carrier on HF bands in the USA).

About our speaker:

Barry was first licensed KN3EUI in 1958 when he was 13 years old and quickly fell in love with CW and 40 meters. After advancing to General one year later and operating on 10m, he was working the world on HF AM and CW. His rig was a Heathkit DX100, so no SSB modes.

Barry’s professional training is in Astrophysics, having worked and studied at Swarthmore College Sproul Observatory, and then further graduate work at Kitt Peak and the University of Arizona. He also worked summers at the Royal Greenwich Observatory (England) and the U.S.Naval Observatory in Washington DC, and then at Flagstaff, Arizona. He spent a sabbatical year and a few summers at Lowell Observatory (Flagstaff, AZ) where he got to have lunch with the man who discovered Pluto at Lowell.

Barry’s teaching career began at Westtown School in West Chester (PA) in 1970, where he taught high school physics, astronomy, and electronics for over forty years. He then spent a year teaching physics at university (West Chester) and Bryn Mawr College.

Barry’s interests in ham radio now include the sound card digital modes, the Nano VNA as a test instrument, and modulation methods on HF SSB and VHF FM using the SDRplay and RSP Spectrum software. He is the net manager of the PaNBEMS net every Sunday morning at 0730 on 3583.0 kHz. He is also active in local county EMCOMM work via ARES/RACES.

Barry is an extra class licensee, and lives in West Chester, PA.

The History of Telegraph Keys

Speaker: Tom Pererra, W1TP

Abstract: The invention of the electric telegraph revolutionized communication and led to the development of all forms of digital technology and the Internet. Messages that would have taken days or months to deliver could be sent in a fraction of a second. As with all revolutionary technological advances, controversies arose about who was the first to invent this technology. Manufacturing companies competed with each other for the lucrative telegraph key market and military customers demanded specialized technology.

As time went on, the earliest telegraph keys became very valuable collectors’ items.

This presentation will trace the evolution of telegraph keys and telegraph key designs, and provide up-to-date information about their current values.

About our speaker:

Tom Perera is a retired professor of neuroscience. He has been an active ham radio operator for over 69 years. He has been collecting and researching telegraph keys since he was first licensed. His telegraph museum website: W1TP.com is the go-to website for all telegraph key information. It contains 3000 pictures and descriptions of telegraph keys most of which he has owned. His book: “Telegraph Key Collector’s Guidebook,” his “Telegraph Key Collectors” CD-ROM library, and his many lectures and demonstrations provide additional information about telegraph key history.
