HOMEBREWER also had regular columns and contributions on membership happenings, field operations, commercial equipment reviews and contesting.


"RF Sniffer a la Pittsburg Style" ... by Joe Porter, W0MQY
Here’s a variation of the now-classic Manhattan style homebrewing technique dubbed "Pittsburg Style" - - a blend of working with etched pc boards, yet retaining the free-form nature of mounting components. The champion of this technique demonstrates how it is used in this simple and useful project for the beginning QRP builder.

"Homebrew Circuit Board Holder" ... by Steve Sellmeyer, WB0QQT
Have you ever tried holding a pc board while tring to solder on some loose components? Or perhaps prop the pcb up on a screwdriver to get just the right light while looking through a magnifying glass? Here’s a custom solution from the Four State QRP Group that’s as much fun to make as it is to use.

"SSB Mods for Miniboots CW Amp" ... by Wayne McFee, NB6M
On the face of it, turning a class C power amplifier intended for CW operation into a linear amplifier suitable for SSB mode requires nothing more than a biasing circuit that will allow the amplifier to be biased for class AB operation. But is it as simple as that? What are the practical considerations of making the change?

"RF Power Meter Cookbook" ... by Joe Everhart, N2CX
Transmitted power is surprisingly tricky to measure -- especially so at QRP levels. N2CX starts us on a two-part exploration of this popular subject by overviewing basic techniques and nuances of low power measurement, with a generous dose of reference material for further study. Part 2 will present a unique working design.

"Manhattan Style Homebrewing Techniques" ... by Chuck Adams, K7QO
What do you do when you don’t have a circuit board and you don’t want to build your project "ugly"? You do it "Manhattan Style" of course! Just glue down some pads and solder the components using the schematic as your guide. K7QO is one of the masters of this technique and he describes his tricks and techniques here in Part 1. Later in Part 2 he’ll present some working circuits.

"Electromagnetic Radiation Probes" ... by David Forsman, WA7JHZ
If the FCC comes calling with a claim of excessive radiation levels in the neighbor’s back yard from your 100 watt HF station, good luck! Build these simple 1.8 to 29.7 MHz electromagnetic probes to determine your FCC OET-65B near-field radiation compliance using a common multimeter. You can measure and demonstrate near-field RFR levels instead of simply predicting it with NEC antenna modeling programs or ARRL worksheets.

"Software Defined Radio with the SDR-1000 Transceiver" ... by M.Klaper, HB9ARK and J.Piri, WD6CSV
Over the last year, AC5OG published a 4-part series in QEX concerning "Software Defined Radio" - a radio architecture in which signal processing is accomplished with software. The series concluded with the presentation of the SDR-1000 transceiver, which is of great interest to homebrewers and advanced experimenters.

"NJQRP DDS Daughtercard" ... by George Heron, N2APB
How many ways can you use a self-contained, high-precision dc-30 MHz signal source contained on a 1" x 2" plug-in circuit board? How about as a stand-alone VFO, a signal generator for your bench, a replacement LO for your Sierra or NC40 transceiver, or perhaps as the heart of an antenna analyzer! Control it with your favorite microcontroller, or even hang it off the parallel port of your PC. Any way you do it, you’ll be generating quality signals for under $20.

"Building the NorCal Keyer" ... by Jim Kortge, K8IQY
The NorCal Keyer is wonderful training project for beginning homebrewers. It’s a programmable iambic memory keyer with beacon, straight key and bug modes, and variable speed control. Veteran elmer K8IQY takes us through construction of this useful kit.

"AZ ScQRPions Class-E Transmitter" ... by Jerry Haigwood, W5JH
Build this easily constructed, stable-frequency and low-cost 3-5 watt Class-E transmitter for use on 40-30-20 meters. With efficiencies greater than 95%, what more could you want!

"TTAM: Test Topics And More" ... by Joe Everhart, N2CX
Veteran QRPer and Hall of Fame member N2CX has a penchant for test and measurement equipment. Actually, it's an obsession, and he shares his ideas and experience with readers in this regular column, addressing in three subheadings each issue: Coming to Terms, Designed for Test, and Stimulus and Response.

"Operator News" ... by Richard Fisher, KI6SN
We are so lucky to have KI6SN as a regular columnist in HOMEBREWER. in his Operator News column, Richard brings us member news, operating tips, strategies, nets, contesting ideas, and more. He authored a regular column in QRPp, and still continues his column in World Radio magazine.

"Radio To Go" ... by James Bennett, KA5DVS/6
Portable antenna designer and experimenter extraordinaire KA5DVS covers aspects of portable ham radio operation. James defines "portable" as any operation away from a fixed station, and we'll see how he travels with ham radio, how he sets up temporary antennas and gear in the field, and tricks and techniques he uses for power sources and cabling. KA5DVS recently opened shop as "Pacific Antenna" with his PAC-12 antenna as a Flagship product, so we'll probably see some examples of field operating with this gem of a design.

"QRP in the Great Outdoors" ... by Ron Polityka, WB3AAL
Few QRPers can compete with the "outdoors" QRP credentials of WB3AAL. Ron takes us on journeys up into the Appalachian Trail and shares his approach, preparation, and weathering experiences in this regular HOMEBREWER column.

"Tuning Up" ... by Richard Arland, K7SZ
QRP Hall of Fame member and QST columnist K7SZ shares with HOMEBREWER readers his unrivaled enthusiasm for rejuvenating and updating QRP rigs of days gone by. This time Rich resurrects the classic Heathkit HW-7 and HW-8 transceivers with a style that puts TV evangelists to shame. Read all about it this time in Rich's regular column with us.

"QRP Contesting" ... by Ken Newman, N2CQ
This column appears in each issue and brings a detailed listing of contests going on over a three month period, including links to the sponsoring organizations providing details for the event. Veteran contester N2CQ is renowned for maintaining this list for various QRP organizations, and he offers some of his contesting wisdom in each issue with us.

"Introducing the American QRP Club" ... by AmQRP Leadership Team
Who is the AmQRP, why was it formed, and what are its goals? Learn all about the club's motivation and direction from its leadership team: KI6DS, N2APB, WA6GER, N2CX and AK1P.

"A Message to NJQRP and NorCal" ... by G. Heron, N2APB and D. Hendricks, KI6DS
The exciting merger of the NorCal QRP Club and the New Jersey QRP Club began on June 4th, and the benefits are already becoming obvious for QRPers throughout the United States. But how does this specifically affect the members of NorCal and NJQRP? Hear from the spark plugs of these organizations how things are simultaneously "the same and better" at the local club level.

"Introducing ... The Az ScQRPions" ... by John Stevens, K5JS
The ScQRPions have been around for some time, and many QRPers throughout the world have benefited from their enthusiasm and esprit de corp. They sponsor the ever popular FYBO and BUBBA operating events, and they are kitting the Class E Transmitter project described in this issue.

"Introducing ... The Four State QRP Group" ... by Dave Bixler, W0CH
So just where is the Four State area in the heartland of the US? W0CH tells us all about this, including the motivated group of QRPers at the core of this newest group to have joined ranks with the AmQRP. These guys are already stepping up to "give back" to all QRPers by hosting an annual QRP weekend called Ozarkcon", and they're kitting and selling the popular KD1JV "Tenna Tuner" as a fund raiser to do so. What an amazing group!

"QRPacificon QRP Forum" ... by Doug Hendricks, KI6DS
Are you going to attend QRPacificon, the oldest and best QRP weekend forum west of the Mississippi?! QRPacificon is being hosted by NorCal on October 17-19 in San Ramon, CA, and will feature some of the best QRP presentations from experts in their respective areas all day Saturday, plus social events on Friday and Saturday evenings. A "Pacificon Kit" will be provided in advance to all those who register and is guaranteed to be the hit of the weekend. (The other best QRP weekends sponsored by the AmQRP are "Atlanticon" on the east coast, hosted by the NJQRP, and "Ozarkcon" in the center of the country, hosted by the 4SQRP Group.)

"Kits from the NJQRP, NorCal and 4SQRP"
We understand how QRPers like kits -- building them, collecting them, talking about them, modifying them and of course using them. Well, a strength the AmQRP Club has as an umbrella organization to affiliated clubs like NorCal, NJQRP and 4SQRP is that you, QRPers of America, get a chance inside HOMEBREWER to see, read about and purchase the collective kitting and services efforts of these clubs.


Micro908 Antenna Analyzer II G. Heron, N2APB and J. Everhart, N2CX
Here’s a low cost, portable, microcontroller-based instrument that automatically determines SWR and reactance characteristics of an HF antenna system. Advanced features of DDS frequency control, LCD tuning display, PC data collection and plotting, numerous operating modes and easy software upgradability make this design attractive for homebrewers and antenna enthusiasts.

RF Power Meter Cookbook II Joe Everhart, N2CX
We learned last time that transmitted power is surprisingly tricky to measure -- especially so at QRP levels. N2CX continues the saga of measuring low power levels by presenting some basic circuits and explaining the subtle nature of their use. Gain a firm understanding of the building blocks in this installment.

Aaron's Clock, No Hands Required Mark Spencer, WA8SME
Typical of any new Ham, Aaron, KD7UCD, wants to operate his station in accordance with the FCC regulations and in a responsible manner. He also is enthusiastic about participating in all of the public service operation opportunities that are open to him now that he is a Ham, including ARES and SKYWARN. Unlike the typical Ham though, Aaron is blind, which complicates many things for him.

Manhattan Project = Sidekick Rx + Tx Jeff Grudin, AC6KW
I wanted more than just building a kit with components that get stuffed into pre-made pc boards. I really wanted to make things as my dad had from the schematic with an understanding of how it all worked. What follows is intended as an inspirational piece for those of you saying “I think I can, I think I can ...”

Multi-band Coil for the PAC-12 James Bennett, KA5DVS/6
Did you build the award-winning PAC-12 multiband portable antenna designed by KA5DVS when it originally appeared in QRP Homebrewer #8? Or perhaps get the kit version from Pacific Antenna? If so, you’re in for a real treat as James describes how to homebrew a single coil for multiband use.

Build the PicWx APRS Weather Station Dave Ek, NK0E
NK0E started this series with a simple PIC16F84A design and has since been adding various hardware and software pieces to create a functional weather station that connects via serial port to your PC or ARPS system. The PicWix project is being presented in a tutorial fashion ... follow along!

Universal Power Supply Dave Ottenberg, WA2DJN
Here’s a simple power supply you can build for the bench for all those common voltages used in your HOMEBREWER projects!

Melt Solder DDS Steve Weber, KD1JV
Steve “Melt Solder” Weber is a master with the ATmel controller chips and he’s designed a circuit with the NJQRP DDS Daughtercard that is super feature-rich. The project serves as a multi-band QRP transmitter on the HF ham bands, with paddle input, dual-memory keyer and speed control, programmable IF offset, EEPROM-stored settings, RIT and XIT split mode operating, LCD display, Rx mute, Tx sidetone generation, and logic to drive an antenna selection relay … Wow!

Manhattan-Style Building Techniques - Cuck Adams, K7QO
Last time, master homebrewer K7QO described the basics of material and tool selection and how he successfully prepares for the project construction. Now read how Manhattan pads are created, mounted and used as circuit nodes on the bare copper-clad base board.

TTAM: Test Topics And Joe Everhart, N2CX
TTAM this time features an integrated theme. Each section describes an aspect of Field Strength Meter (FSM) technology. The first section, Designed for Test, gives a brief overview of FSM telemetry and describes the basic module used for the remote-reading function. Then Coming To Terms defines terms and a method for preprocessing the information to be sent to make it easier to interpret. Finally Stimulus and Response gives some clarification and enhancement for adjustment of the NJQRP FSM, the Sniffer.

QRP Operating: “Well-Oiled Dummy Richard Fisher, KI6SN
Regardless of the power level at which we operate, in front of mind is good amateur practice – clean, melodious signals and an adherence to operating procedure and codes that would make the late Hiram Percy Maxim, W1AW, proud. To that end, this quarter’s QRP Operating looks at a well known, but not-often-enough-used station accessory that allows testing of transmitting gear without sending signals – good or otherwise – into the ether. Every radio experimenter should have a non-radiating RF dummy load in his radio shack.

Radio To Go: “Antennas To James Bennett, KA5DVS/6
Last time around, we looked at options for portable power. This time I will cover some options for lightweight portable antennas and take a look at what works and why.

QRP in the Great Ron Polityka, WB3AAL
The other day I was asked a question from a fellow QRP operator. He would like to take his QRP radio to the field and operate from the Great Outdoors. Joe was wondering what he would need for a day trip. This is a very good question that many people never give too much thought; they just make the mad dash out to the wilds.

Tuning Up: “Sniff, Sniff, Richard Arland, K7SZ
Why does the average ham need a Field Strength Meter? Quite literally, this one device can be used to do a multitude of things including: checking transmitter output and the outputs of various stages within the transmitter, comparison of antennas in the near and far RF fields, obtaining a rough estimate of a directional antenna pattern, and sweeping your shack for RF bugging devices – hey, I’m not paranoid!

QRP Ken Newman, N2CQ
I'm guessing that the average HOMEBREWER subscriber is "melting solder" more often than into contesting. QRP however has many other fun outlets and what could be more fun than making your own rig or kit and using it in a contest to see how it well does? Plus, three month forecast of contesting events.


A Nuts and Bolts Approach to RF Wayne McFee, NB6M
Let’s say you are like many other homebrewing hams ... you might have a limited understanding of how radio circuits work and don’t have a shack full of test equipment. You probably have an HF amateur band receiver, an oscilloscope, a digital multimeter with an RF probe, an SWR meter or bridge, a dummy load and an antenna. You have a basic set of tools and you have at least begun to get comfortable with the Manhattan, Island, or Ugly style building methods. And most important, you have the desire to design and build some gear of your own. If you fit this profile, this project is for you!

Getting started with Surface Mount Ron Skelton, W6WO
Look inside any commercial modern rig and it is hard to find more than a few traditional components. Gone are the brightly colored resistors and capacitors with clearly marked values. Tiny anonymous rectangular chips known as surface mount devices (SMDs) have taken over and much of our compact technology would be impossible without them. At first glance this can be discouraging to experimenters and home brewers as clearly such complex products cannot be built, or in many cases even repaired, by human hands ... but take heart - it’s not as difficult as you might think!

Surface Mount Construction George Heron, N2APB
“Oh no, this project uses SMT parts!” Some homebrewers recoil at the thought of assembling a kit that uses surface mount technology (SMT) components. They fear the parts are too small to see, handle, solder or debug when assembled. I had these same concerns until I tried it and found that it wasn’t so difficult when using the right tools. Further, I discovered some benefits of using SMT parts that made my QRP projects smaller, lighter and more portable for optimized field use.

A Detailed Look at Transmission Line Rick Hiller, W5RH
Transmission line power losses are extremely important at QRP power levels. A marvelous (and free!) software program called “Transmission Line Details” shows you what you are losing and why.

They say beauty is in the eyes of the beholder. For W1REX, every piece of old, discarded, rusty or malfunctioning equipment is a diamond in the rough. Rex starts here a short, irreverent series of “mission impossibles” that may just give you some ideas of your own.

Hacking the K8IQY Precision Nick Kennedy, WA5BDU
I really like the Precision VXO circuit that appeared in the Atlanticon 2002 Proceedings and later in QRP Homebrewer. With the kit available you can end up with a really nice looking signal generator. I wanted to customize it a bit, so I started putting it together Manhattan-style. Here’s the tale with some of the variations I put in and some things I learned along the way. Some response from K8IQY has been added, along with an interesting analysis of the Norton amplifier.

Manhattan-Style Building Techniques - Chuck Adams, K7QO
In Part 1 master homebrewer K7QO described the selection process for material and tools, and in Part 2 he described how Manhattan pads are created, mounted and used as circuit nodes on the bare copper-clad base board. In this concluding installment, Chuck overviews the basics of soldering and converting a circuit diagram from paper schematic to a Manhattan-style layout.

A Kinda, Sorta Inverted Bob Logan, NZ5A
Here is an antenna that tunes all HF bands quite nicely, including the new 60 Meter band. Its performance not only consistently equals that of my old 80-Meter and 40-Meter inverted vees at 35 feet, but much of the time it outperforms them! The simple antenna also exhibits some gain on all bands above 40 Meters, and a low angle of radiation helps on long-haul QSOs as well.

Power Isolator for a Digital Panel John Farnsworth, KW2N
Ever been tempted to buy one of those digital panel meters (DPM) advertised for around $10-$15? They look inviting: 3-1/2 digit readout, about 1% accuracy, and they could give that professional look to your next project. You can use them to display voltage, current, or other parameters with appropriate shunts or dividers. They are available from Marlin P. Jones, All Electronics and others. But there’s a catch.

Fishing Pole Vertical for Twenty Ron Stone, KA3J
Building this light weight, inexpensive antenna is a snap!

TTAM: Test Topics And More: Joe Everhart, N2CX
Many homebrewers and most QRP operators frequently rely on batteries to power their equipment. Naturally all of us want to get the most we can from batteries so while the column won’t tell you which is the ultimate battery, Coming to Terms discusses a number of battery characteristics, and Designed for Test shows how to perform battery life measurements based on understanding what makes them work.

QRP Operating: “Minimalist’s Approach to 10M Richard Fisher, KI6SN
Due to impending house repairs and wind damage to a fence that my 40 meter full wave stealth loop runs (or rather, used to run) along, I took the loop down recently. That was my one and only all-band antenna. That left me with no antennas - almost, except for a borrowed 40 meter DCTL (Distributed Capacitance Twisted Loop) that I was playing with. Oh, and the ARRL’s 10 meter contest was on that weekend. What to do?

Radio To Go: “For the James Bennett, KA5DVS/6
While I write this column, I am in an airliner at about 35,000 feet on a flight to visit family for the holidays. Sitting here, I began to think about the things that go into preparing a station to take along when traveling by air. Not only how to pack but what to pack. When traveling by air, what we can carry as what we are allowed to carry may limit our ability to play radio at our destination. Since I travel frequently, I thought I would share a few ideas for successfully taking radio equipment along when flying.

QRP Ken Newman, N2CQ
Three month forecast of QRP contests, Results of the Spring QRP Homebrewer Sprint, and rules for the AmQRP “Look Around in the Field” contest.


IQ-VFO ... a High-Performance DDS-based VFO Craig Johnson, AA0ZZ
Back in 1997, radio frequency homebrewers really began taking advantage of the conveniences that DDS technology offered: 1-chip simplicity, DC-to-30 MHz signal generation ability and relatively decent signal purity. Since then, AA0ZZ and others have been creating and refining signal generators using this technology. The author began working with one of the latest DDS chips from Analog Devices, with an end goal of designing a 0-60 mHz VFO for use with the recently introduced KK7B high-performance R2PRO receiver. This the AA0ZZ story of taming the AD9854 dual-output (I-Q) DDS chip and creating a PCB in the process that others can also use. Additionally, your friendly Homebrewer editor has documented his enclosure for the project, creating a modular high-end VFO component for use on the bench. AA0ZZ and the NJQRP are also making his pc board and PICs available to help others construct this high-performance HF VFO.

Harnessing Harmonics in the IQ-VFO -- Craig Johnson, AA0ZZ, Jim Kortge, K8IQY
The spectral purity of a DDS-based VFO has been the subject of great debate in the technical community. Much of the discussion is related to earlier generations of DDS parts which feature Digital to Analog Converters (DACs) that are not as good as that on the AD9854 used in the currently popular IQ-VFO design. Designer AA0ZZ, along with noted QRP Hall of Fame member K8IQY give this topic some serious study.

Nuts & Bolts of RF Design - Part 2 -- Wayne McFee, NB6M
This homebrew transceiver was the subject of a presentation made during the QRP Symposium at Pacificon 2003. I focused on the process of designing and building this transceiver from scratch by selecting portions of proven circuits and stringing them together in order to achieve the desired result. In the previous issue, I presented a step-by-step approach to designing and building this rig using some simple "nuts and bolts" techniques. This time I’ll take you through the detailed circuit analysis, measurement and tuning procedures.

RF Power Meter Cookbook - Part 3 Joe Everhart, N2CX
This installment outlines test methods and simple circuits used to test RF power meters when you don't have access to expensive lab-grade equipment. N2CX focuses on testing below 30 MHz to demonstrate principles without resorting to special techniques.

Build the PicWx APRS Weather Station - Part 6 Dave Ek, NK0E
NK0E started this series with a simple PIC16F84A design and has since been adding various hardware and software pieces to create a functional weather station that connects via serial port to your PC or ARPS system. This time Dave adds an atmospheric pressure sensor to this ongoing fun and educational project.

A Homebrew PAC-12 Antenna -- Richard Meiss, WB9PLU
WB9LPU takes the basic design of the very popular KA5DVS "PAC-12" portable multi-band vertical antenna and makes it sturdier and more easily assembled in the field.

Etching PC Boards at Home -- Robert "RC" Conley, KC5WA
Here's how RC followed the lead of AB5XQ, and improvised a little along the way, to homebrew a pc board for the Pixie 2 QRP Transmitter. With just a handful of parts from some local suppliers, you too can make a great-looking pcb for that next project!

"Slap, Click, Twang" ... Morse Code the Old Way -- Mark Spencer, WA8SME
A simple interface that will allow you to use a telegraph sounder to copy code like they did in yester-year

SPICE Modeling Tutorial -- Chuck Adams, K7QO
SPICE, an acronym for Simulation Program with Integrated Circuit Emphasis, is a computer program developed at the University of California at Berkeley . Since it was developed with public funding, the program became public domain and is readily available from several sources over the Internet. I will give you pointers to sources that I know of at the end of this tutorial and hopefully you will not procrastinate before they disappear.

Photo Documenting Construction of the NorCal BLT Tuner Kit -- Robert "RC" Conley, KC5WA
When RC asked if we wanted to see a few photos of how he constructed his original copperclad-enclosed BLT Tuner Kit, we of course said "Sure!". But when he sent over his photo-journalism work, we nearly fell off our work stool ... we think you'll be equally impressed!

TTAM: Test Topics And More - "Good Enough Q" Joe Everhart, N2CX
This time N2CXl describes how to connect some basic building blocks to measure Q and how to use almost the same methods to measure Q with some test gear you may already have.
