Paladin Flory, KX7PC, received his first amateur radio license in 1963. He is an ARRL Registered License Instructor and an ARRL Amateur Radio Emergency Communications Courses (ARECC) Field Instructor. He also spent 10 years on the Park County (WY) Search and Rescue squad, where he served two years as Education Officer.Emergency communications (EmComm) in ham radio is as old as the amateur radio service. For many hams, it is the reason they got into ham radio in the first place. The ARRL has developed a mentored online course, EC-001: Introduction to Emergency Communication, designed to give amateur radio operators a core set of knowledge that should be portable to any EmComm group.

This forum will introduce you to what you will learn in the full online course, as well as practical information for taking your EmComm skills OUTDOORS! Folks interested in any type of Public Service communications should find this forum valuable.

Greg Galka, N7GT, is the Network Engineer for the Wyoming DMR Project.  He holds an FCC Extra class license.

Greg will be giving a brief overview of what the Wyoming DMR project is, its goals and objectives, and some of the technical aspects of Motorola MotoTRBO (aka DMR), which will include describing a timeslot, talkgroup, color codes, TDMA, contacts list, obtaining a subscriber ID, master vs. peer, and finally the cBridge.  He’ll be discussing what type of radios can be used on the network (Motorola, CSI and TyT) and describing some of the differences.  A brief discussion of what a codeplug is, how it’s developed, and loaded in to the respective radio as well as operational procedures when accessing the Wyoming DMR Network.

Ron Gallo, WR8O, holds an FCC Extra class license.  He activated several locations during the 2016 National Parks on the Air (NPOTA) program and has created the GOTA stations for ShyWY ARC operations for Field Day. Ron not only activated locations in Wyoming, but he also activated Sitka National Historical Park in Alaska.

Ron will discuss logistics, the site challenges, and his stint at the Park.

Sean Kutzko, KX9X, is the ARRL Media and Public Relations Manager.  He operates portable a lot and activated several NPOTA locations.  He has also operated from several DX locations in the Caribbean.  You may have heard him as one of the members of the Spurious Emissions band at HamVention.

Shel Radin, KFØUR, holds an Extra class license and has been licensed since 1965.  He enjoys the many facets of our hobby…DX’ing, Ragchewing, and Contesting using a variety of modes…CW, SSB, RTTY, and PSK.  For the last 16 years, Shel has been active in QRP portable operations, hiking on the trails of the Rockies, and recently as an “activator” for the National Parks on the Air program.  Shel’s “Easy QRP Portable “presentation will show how easy it is to go QRP portable with a simple, lightweight setup, and achieve great results.

He will describe and demonstrate his portable operation, including the rig, antenna, power source, and accessories.   Included are pictures and results for 33 recent National Parks on the Air outings, showing the variety of places to enjoy operating.

Rob Steenburg, ADØIU, is a space scientist at the National Weather Service’s Space Weather Prediction Center in Boulder, CO.  He entered the space weather field over a decade ago after serving 20 years as an Air Force meteorologist.   He has been a licensed radio amateur since 1980 and enjoys CW QRP operating and building and repairing equipment. Space weather impacts radio amateurs.

His presentation will describe the types of space weather, the impacts on radio operators, and the new developments in space weather research and operations.

Chris Smith, NXØE designed HF (and LF) antennas at TCI in California, worked in defense in “applied electromagnetics” for Lockheed and Kaman Sciences, and at Delfin Systems he re-designed the portable direction finding antenna that is part of the AN/PRD-13 manpack DF system.

Chris will discuss the design and analysis of some portable antennas, using free software: 4NEC2 to do the analysis, JJ Smith to look at transmission lines and matching circuits, and (time permitting) W6ELProp to look at propagation probabilities.

Rob Sherwood, NCØB, was first licensed in 1961.  He maintained the 50KW AM and FM transmitters, microwave links and studio gear at KOA in Denver for almost 20 years.  In 1974 he founded Sherwood Engineering building upgrades for Drake R-4Cs.  He publishes comparative receiver performance tables on  He has spoken at Contest University in conjunction with HamVention for 10 years.  His station is in a rural setting N of Denver.

Discussion of the state of the art today, and is that level of performance necessary most of the time? Regardless of what rig we own, how can we make it perform to its maximum in a DX or contest pile-up?  What do the main transceiver specifications mean, and why is sensitivity (noise floor) often misunderstood?

James Kretzschmar, AE7AX, retired from the U.S. Air Force in 2004 after a 25 year career as a general dentist.  He was awarded the “Best Humanitarian Impact” category prize in the 2016 Texas Instruments Innovation Challenge competition for his entry; “Futuristic Energy Saving Lighting System, Color Influenced Temperature Perception”.  His project involved temperature input to a microcontroller for regulation of RGB LED room lighting.  James enjoys all aspects of electronics, homebrew projects, 40 meter CW operating, and bicycling. James has a unique approach to building homebrew gear.

He will describe the challenges, parts procurement, methods, circuit boards, enclosures, testing, and some simple first projects.  Nothing beats the thrill of making a contact with a radio you made yourself.

George Hirst, WF4U, was first licensed in 1962.  George is an Electrical Engineer. During the first 15 years of his career he worked primarily on VLF/LF propagation and systems. He served as an US Air Force officer and also worked at the MITRE Corporation.  In 1998 he retired and moved from Virginia to Cache Valley, Utah where he has plenty of room for his antenna farm. This allowed him to develop his current interest in low band DXing.  George is a member of the Utah DX Association, was named DXer of the Year for 2013, and served on the UDXA Board of Directors in 2015 and 2016.

George’s presentation will give an overview of low band (40, 80, and 106m) propagation and antenna design (both transmitting and receiving). WF4U’s antenna farm will be described using photos and drone videos. Finally, operating suggestions will be made and resources will be listed where further information can be obtained.

Walt Marshall, W7SE, has been radio active since 1955.  He is a lifetime ARRL member and Amateur Extra class operator.  His primary interests are contesting, DX and building a competitive station.  He has had opportunities to operate from several DX locations in Europe, Asia and South America.  Walt lives in Laramie with his wife Dolores, KA7MPB.

Walt will discuss amateur radio operations from HZ1AB in Saudi Arabia from 1980 – 1994:  QTH, History of the station, Station equipment and antennas, Operators and activities, QSLs.

Bob Rennard, N7WY, was “elmered” by W7VNJ and became a novice in Casper in 1961.  In 1976 he earned an Extra class license, and became N7WY.  His early ham activities were primarily homebrewing.  After a 25 year hiatus, he returned to HF and set becoming a proficient CW operator as a primary bucket list objective.

Bob will give an introductory talk on contesting, why hams get into it, a simple station configuration, the impact of computers and software, preparing for a contest, and the personal and external rewards.

Dean Summers, N0ND, is a 1977 graduate of North Dakota State University with a B.A. in Speech/Broadcasting.  He was selling for nearly 30 years with Northwestern Bell Telephone in Bismarck; and Business Voice and Data Systems and Pharmaceutics for GSK and Novartis.Dean has organized and completed special operation stations for North Dakota State’s 125th anniversary at Bismarck on the state capitol grounds in 2014; planned and executed the NPOTA by KØNP, a three day event at Theodore Roosevelt National Park; and designed special QSL cards for all these events. Dean collects call sign plates bearing ND.

Dean will talk about how to preserve efficiently your paper QSLs and other information using a digital archive.

R.J. Bragg, WY7AA, has been a ham since 2008.  He primarily operates SSB and JT-65 from his station west of Cheyenne.

R.J. has worked at McMurdo Station, Antarctica since 2006 will talk about operating as KC4USV from McMurdo, as well as the history of HF and amateur radio as part of the United States Antarctic Program.

Bob Overton, WA7JRF has been a licensed ham since 1970. He worked in telecommunications 35yrs for the BNSF railroad, and taught Electronics at Yakima Valley JR College and held a Commercial Radio Telephone license for 37years. He instructed electronics in the Navy, also Leadership, Land Navigation and Maintenance in the Army. He is a retired Army First Sargent, and has served as Section Technical Advisor and two tours as Section Emergency Coordinator.

This forum covers protecting two meter repeaters and base stations with a quarter wave shorted stub. Bob will teach the theory of a quarter wave shorted stub and how it can be used to protect radio equipment, and also a little about grounding towers and equipment.
