TABLE OF CONTENTS

Welcome!

We have an incredibly exciting issue of Homebrewer Magazine this time, as you may have already noticed.  It contains seventy-two unique homebrew construction projects and even more great material in the form of reviews, contesting results and contributions from our regular columnists. All of this is provided in more than 400 full-color, high-resolution pages!

This is our second issue in the new CD-ROM format and most of the kinks now worked out. Most notably, all article material is in PDF format, allowing everyone to view the content on any computer, regardless of type or operating system.  We even went back and re-formatted issue #4 this way to allow subscribers to also have that past issue in the nicer format.

We again included all previous issues of Homebrewer Mag on this CD.  So you have the full set of issues 1-5 here on this disc making this issue additionally special; this is the last time these prior issues will be included.

I am particularly thrilled to have so many contributing authors from our QRP community this time. This is a testament to the value and usefulness of our efforts with the magazine. I urge you to especially see the articles by giants in our midst: Paul Harden NA5N, Mike Czuhajewski WA8MCQ, Joe Everhart N2CX, Jim Fitton W1FMR, Charlie Lofgren W6JJZ, and Wayne McFee NB6M.  Some authors continue to pump out great material that I’m sure you will enjoy: Dave Ek NK0E, Dave Ottenberg WA2DJN, Ron Carr WA1VGB, Fred Bonavita K5QLF, Jerry Haigwood W5JH, Phil DeCaire WB7AEI, Terry Fletcher WA0ITP, Ron Stone KA3J, Jim Giammanco N5IB, and Doug Wilson WA0SVL.  Our regular columnists also have great stuff this time: Richard Fisher KI6SN, Rich Arland K7SZ, Joe Everhart N2CX, and Ken Newman N2CQ. First-time author Frank Roberts, VE3FAO, has a terrific feature article you should see. Other first-time contributors offer a plethora of interesting projects to keep you busy in the shack this summer: Dar Piatt W9HCZ, Wade Lake KR7K, Verner Blindheim, Nancy Feeny NJ8M, Bob Hillard WA6UFQ, Mike Hasenfratz WA6FXT, Ron Pfeiffer N1ZSW, and others. We are so fortunate to have the involvement of such a fine group of authors, and I thank them all from the bottom of my heart.

This issue also contains extra material on the CD that is impossible to provide in other magazine formats.  George Murphy VE3ERP graciously allowed us to distribute his wonderful collections of HamCalc software utilities, and Ron McConnell W2IOL allowed us to do the same with his Great Circle software. To help you in using these software tools, we have also included some instructional articles concerning them.  Another “extra” is that we have the audio soundtrack from three of this year’s Atlanticon presenters (KK7P, K7SZ and K8IQY), and you can listen to these hour-long audio tracks while viewing the slides we saw earlier this spring in Timonium, Maryland. Pretty neat!

As with the last issue, we’ve included the recaps of all previous Atlanticon QRP forums, including this year’s event and the massive photos albums of each of them in a nice easy-to-use photo browser. And remember that popular presentation many of us have used to explain what QRP is all about at local our clubs?  This Why QRP? presentation has been updated and is included on this issue’s CD.

So sit back in your computer chair and enjoy digging through Homebrewer #5 – it should take you several months to do it all! Print out selected articles an take them to the “reading room” or put the files on your PDA for remote study, as N2CX does. We believe Homebrewer CD Magazine is a unique and valuable contribution to our hobby and all of us writers and editors are very proud to produce it for you.
