April 17 - "Fun With Electric Motors" Karl Berger, W4KRL reviewed the fundamentals of direct current motors and ran tests on a century-old open frame dc commutator motor that has slip rings connected to one rotor winding. This enabled observing the rotor voltage on an oscilloscope. All control of the motor control was done with an Arduino using Pulse Width Modulated power supplies, Hall-effect current sensors, and servo-driven instrumentation.
March 20 - "An Amateur-Radio Solution to Frequency-Hopping Synchronization" André Kesteloot N4ICK and Maitland Bottoms AA4HS jointly presented a creative approach to the spread spectrum challenge posed by André in his December 2013 presentation.

André Kesteloot, N4ICK, demonstrated an Arduino-based "Spread-Spectrum Frequency-Hopping Transmitter Module" that he has developed. André needs ideas for the receiver side of the system. AMRAD members engaged in a lively discussion about how the receiver could detect and lock on to the transmitted signal.
November 21 - Bill Liles, NQ6Z “100 Years of Amateur Aerials” The Radio Society of Great Britain is 100 years old this year. For the celebration they have gone through their archives and produced a set of talks. One talk is on 100 years of amateur aerials. Bill presented this talk with photos and discussion.
October 10 - Ron Payne, WA6YOU - "Coax Connectors - The Intimidating Interface." Ron demonstrated installing PL259 and BNC coax crimp connectors and weatherproofing methods.
September 19 - Mark Braunstein, WA4KFZ, provided an overview of printed circuit board fabrication for the electronics experimenter. Mark has personal experience using CNC routers in a commercial enterprise. Other options for do-it-yourselfers include conventional photo-etching and contact etching with laser printed masks. A number of domestic and foreign fabricators offer fast turn around at low cost but with confusing choices for software and file formats.
August 8 - Maitland Bottoms, AA4HS, introduced us to digital voice communications on HF using FreeDV software. FreeDV is an application for Windows, Linux and MacOS (BSD and Android are in development) that allows any SSB radio to be used for low bit rate digital voice. The software compresses speech to 1400 bit/s then modulates a 1.1 kHz wide quadrature phase-shift keying (16-QPSK) signal which is sent to the Mic input of a SSB radio. On receive, the signal is received by the SSB radio, then demodulated and decoded by FreeDV. Communications is readable down to 2 dB S/N, and long-distance contacts are reported using 1-2 watts power.
July 18 - Dr. Frank Eliot, W3WAG, discussed Weak Signal Detection. Thanks to the rapid increase in digital processing availability, hams have implemented sophisticated and user-friendly techniques that enable us to communicate with much weaker signals than we had dreamed of exploiting just a few years ago. In this session, Frank discussed weak signal detection, exploring under what circumstances we might detect even weaker signals, thus communicating over even more difficult paths. Also, on a related topic, he described how earth antennas behave, and experiments one might perform to sort out their modes of operation.
June 13 - AMRAD hosted a doubleheader for slow modes: DFCW and JT65.
The first presentation was by André N4ICK titled An Arduino-based DFCW Beacon for the 479 KHz Band. André discussed Dual Frequency CW (DFCW) and updated us on the ARRL petition to the FCC Office of Engineering and Technology regarding the new band. He demonstrated his design of an Arduino-based 479kHz beacon, and expanded on the eventual possibility of "crossing the Pond" to communicate with British Hams who have been experimenting for a while with this new allocation.
Dual Frequency CW, or DFCW, is a technique where a CW signal is transmitted at a very slow symbol rate, typically at 3 seconds per dot. This allows reception in very narrow bandwidths.
Terry McCarty, WA5NTI, made a presentation on The JT65 Weak Signal Digital Soundcard Mode. JT65 can decode signals many decibels below the noise floor making an exception to the old rule “if you can’t hear them, you can’t work them.” Terry has racked up an impressive list of contacts on nearly every band. The mode was developed by Joe Taylor, K1JT as an offshoot to his WSJT weak signal mode widely used in moonbounce contacts. Although JT65 was originally intended for troposcatter and Earth-Moon-Earth paths, Terry is one of the pioneers in using it for low power HF contacts. Terry told us where to get the free software, how to configure it, and what you can expect in a contact.
May 9 - Karl Berger, W4KRL, shared his adventure exploring the possibilities for using the Arduino microcontroller in amateur radio projects. Karl set out a few months ago to make a stand-alone touch screen display for a portable antenna analyzer. He broadened his objective to include a flexible graphic display system that a ham can adapt to station control, test instruments and data logging. Along the way, he overcame challenges in converting his program from “in line” coding to the “object oriented” style and solving unexpected problems with hardware control.
April 11 - Ron Payne, WA6YOU, demonstrated how to build UHF Yagi antennas for receiving off-air DTV stations, or, for any UHF band application. Ron demonstrated his method of building antennas using spun copper wire for the antenna elements and how to get great results with low cost construction.
