Building Your First Repeater

Kenneth Finnegan, W6KWF

Countless radio amateurs use repeaters on a daily basis, but what goes into one behind the scenes to get one on the air and keep it running? This is an overview of what’s involved in building amateur repeaters, and why you would (or wouldn't) want to build your own. Topics will include identifying the goals for a repeater, finding a radio site, and an overview of all the equipment needed to build a repeater.

Kenneth Finnegan, W6KWF was first licensed in 2008 while attending UC Davis studying mechanical engineering. After graduating with his BS, he transferred to Cal Poly SLO to get an MS in electrical engineering and became involved with the Cal Poly Amateur Radio Club - so involved that his master's thesis ended up being related to amateur radio: "Examining Ambiguities in the Automatic Packet Reporting System."

He now works as a Solar Applications and Test Engineer at a small solar cell supplier called Solar Junction where he tests record-breaking GaInNAsSb solar cells (cf. U.S. patent nos. 9,018,522 and 9,252,315 et al.) for a living.

So You Want to do SOTA?

Tim Fairbairn, AF6TF

Tim Fairbairn, AF6TF is an avid hiker and HF operator who enjoys operating HF radio from remote wilderness locations, especially mountain peaks. Tim explains his adventures with Summits on the Air (SOTA). He talks about wonderfully lightweight gear and equipment but the real draw turns out to be the spectacular destinations.

Tim Fairbairn, AF6TF, has been involved in electronics since the 1970's. He worked at Intel during college and now works in the audio/video industry, managing wireless microphone frequencies for multiple customers. When his youngest child was about to enter college, Tim took up Amateur Radio and got his Technician license and call sign KJ6RNN. He upgraded to general the next year. His wife got interested and got her Technician license and call sign KK6FOW. Somehow, the bug bit harder causing Tim to cram, pass Extra, and became AF6TF. He was looking for ways to operate while outdoors when Bay-Net offered a simple hike to a local peak in a park. Tim packed up his Icom IC-7000, 40Ah battery, and some long wires – basically taking his home station outside. From that experience, Tim learned quickly the importance of using lightweight gear. He has since become an experienced SOTA operator with many tales of adventures.

DMR – Digital Mobile Radio

Ed Fong, WB6IQN

This meeting is one week earlier than usual. It has been scheduled for the 3rd Friday instead of the usual 4th Friday of the month. Be sure to put the correct date on the calendar.

Digital mobile radio (DMR) is a mode that is getting really popular. The radios cost about $100-$150 depending on the quality you want. All of them also have conventional FM. DMR is a full digital format that is interfaced via the Internet where one can talk 24/7 all over the world. The dream of working DX while sitting on your couch is here. Since DMR is an open system originally set up by Motorola there are over 15 manufacturers of DMR radios, both hand-held and mobiles. Learn how to get register as a DMR user, where to purchase a radio, how to program the radio and talk to the world without depending on propagation conditions.

Ed Fong, WB6IQN, teaches RF Wireless Communications and I/O Design Fundamentals for UC Santa Cruz in Silicon Valley. He taught RF Wireless at UC Berkeley from 1998 to 2011.

Ed is the owner of Ed’s Antennas https://edsantennas.weebly.com. More than 12,000 of his DBJ-1, DBJ-2, and TBJ-1 antennas have been sold to hams, commercial users, and agencies. These popular antennas have been featured in QST (March 2017, February 2003 and March 2007), CQ (Summer 2012), ARRL Antenna Compendium Vol 8, and ARRL VHF/UHF Antenna Classics.

Ed’s past presentations to FARS were on single-sideband modulation (January 2023), ground-independent vertical antennas (August 2019), and DMR radio (April 2018).

Dipole Resonance and the Mysterious Antenna Factor K

Steve Stearns, K6OIK

Dipoles and monopoles are examples of linear cylindrical antennas and are the foundation of amateur radio antennas at frequencies below 1 GHz. The theory of such antennas was developed in the first half of the 20th century. In this talk, Steve, K6OIK talks about dipole resonance, stored field energy, and why the resonant length of a half-wave dipole isn’t a half wavelength. The strange story of the ARRL’s mystery graphs of the shortening factor K will be told.

How to Make Antenna Models

Steve Stearns, K6OIK

Steve, K6OIK, shows antenna modeling capabilities in real time. He demonstrates putting antennas on real terrain, cars, and planets with dielectric trees. He makes and runs the car model from scratch, duplicating the FEKO model featured in QST, October 2016, of a 2-meter whip on the roof of a car. Field animations shows where “hot spots” exist inside the car.

AES Mesh Radio for Fire Communications and Emergency Responder Radio Coverage Systems (ERRCS)

Daniel Tate, KM6CSO
Tony Lacatelli, KK6JVB

[Meeting scheduled in Room 32 this month]

Daniel and Tony explain mesh network and how encrypted radio mesh networks are used in fire protection and first responder operations. A mesh network is a distributed communication network that does not require base stations. Instead, messages pass from neighbor to neighbor. Somehow messages manage to find a path between two connected users. The advantage of mesh networks is they can be deployed quickly and without the cost or time needed to build fixed base station or repeater infrastructure. This makes mesh networks attractive for emergency or disaster communications at VHF and UHF frequencies as an alternative to HF NVIS communications. The nodes of a mesh network can be set up to digipeat messages without operators in the middle, as messages are relayed from node to node automatically. Daniel and Tony talk about their Advanced Encryption Standard (AES) Mesh Radio systems for Fire Communications and Emergency Responder Radio Coverage Systems (ERRCS). They give a basic overview of the technology and describe practical operation.

Daniel Tate, KM6CSO, is a Senior Systems Designer at Intrepid Electronic Systems. Daniel has over 20 years of experience in Fire Protection and 4 years of experience in AES Mesh/ radio.

Tony Locatelli, KK6JVB, is Director of the ERRCS/DAS Division of Intrepid Electronic Systems. Tony has over 25 years of experience in Fire Protection and 5 years of experience in ERRCS and DAS. Tony holds a FCC General Radio Operator License (GROL).

SimSmith Smith Chart Software: The Simple to the Sublime

Ward Harriman, AE6TY

Ward is the author and creator of the SimSmith Smith Chart software package. Ward presents a live demonstration of SimSmith in action and how it is used. He starts at the ground level aimed at the novice and progresses to advanced capabilities for the experienced user.

The presentation starts with basic Smith Chart layout and utilization: plotting impedances, constructing circuits, exploring circuit element effects, importing load files, and analyzing system performance. Early versions of SimSmith were limited to single-frequency ladder networks, but the tool has evolved to analyze arbitrary networks at multiple frequencies.

Ward demonstrates the more powerful features of SimSmith, which include multi-variable circuit analysis, backward Smith Chart operation, the construction and analysis of multi-frequency matching circuits, bidirectional circuit analysis, the construction and analysis of non-ladder circuits, and advanced plotting capabilities. For those wishing more, SimSmith is the subject of dozens of instructional videos available on YouTube.

Ward Harriman is a retired computer hardware engineer and ham radio enthusiast. Mr. Harriman spent 25 years building Internet switching equipment at a variety of startup companies.

In 2005, Ward changed gears returning to the study of RF circuits and Digital Signal Processing. He obtained his extra class license (AE6TY). He has designed, built, programmed, and operated his own CW/QRP/SDR radio ever sense.

Mr. Harriman is the author of SimSmith, a highly interactive RF circuit analysis tool. Ward spends much of his amateur radio time on expanding SimSmith’s capabilities and refining the user experience.

The winner chose the QB25, so the HTDV and Ematic will be offered at future raffle(s).
