Below are before and after photos of the front panel. The first photo is my attempt to drill out holes in an enclosure i purchased from Ten-Tec based on the template provided with the kit. I really lacked the proper milling tools to do the job and, needless to say, it shows.
The second photo is the front panel I designed, again based on the template provided in the kit. The software I used to design the panel layout was provided by Front Panel Express online. (the software I downloaded from Front Panel Express for my Mac work flawlessly) Using the software I positioned and specified sizes for each panel opening. In addition I specified labels for each opening.
I learned that I should have allowed a bit more room for panel openings as the position of components on the board was slightly different than my front panel specifications. I had to enlarge two of the openings using a Dremel bit to adjust for two jacks whose position was slightly off from my specifications.
In addition I learned that I should have positioned my labels a farther from the openings as the connector fasteners tended to overlap my labels somewhat.
All in all I think this was a very successful first attempt.

My 5W station and simple dipole attached to my roofline at about 20 feet and open wire twin feedline worked almost all parts of the world: from Central & South America to Europe, Africa, Asia (Russia and Japan) and New Zealand.
15 and 10 meters were really hot during daylight hours and are where I made most of contacts. 20 meters, at least for me, was dead, netting me just 1 contact. 40 meters was just OK.
I set a goal for myself to work 100 stations with the time I had available. I ended the contest just before time ran out with a contact to Guam, which was contact number 101.
My KX3 performed like a champ on a set of 8 rechargeable batteries. The rig's ability to dig weak signals out of pile-ups and sometimes marginal propagation conditions was very impressive.
My best contacts were Montserrat and Senegal which I never expected to work. Conditions were so good I worked Montserrat on multiple bands.
Looking forward to next year's contest!

Within the first few minutes I responded to V73NS calling CQ, having no idea about his QTH. Turns out it was Neil Schwanitz in the Marshall Islands! What good fortune for me. As soon as I signed off there were lots of stations calling him. I must have hit it just right since I doubt my 3W would have punched through the pile-up.
From there I QSO'd with Ted in Sioux City, Nebraska, then N1WPU in Maine. I also worked Valery, UA0ZC in Russia.
For me, this is some of Ham radio at its best!
Here is a photo of my gear and antenna just prior to set-up.
Then I asked my XYL, who has considerable sewing skills, whether she could make equipment covers for me.
After a brief consultation as to color, fabric and size and a trip to the local fabric store she had what she needed. One week later I had two very sharp-looking dust covers. See before and after photos below.

I loaded the KX3, my speaker wire dipole, portable key, and AA batteries in my backback, jumped in the car and headed over.
The clump of trees seen in the aerial view on this page shows where I set up for FYBO.
The sun was shining, not a cloud in the sky, the wind was blowing. Perfect day! I had forgotten to bring a chair and my headphones, but luckily for me, there was a bench waiting for me. It was quiet enough that I did not need my headphones. So, I tossed my dipole into the trees, leaving the center about 6 feet above the ground. Hooked up the KX3 to the antenna, plugged in the key and battery pack and started scanning for FYBO CQs.
As a started scanning on 20 meters I heard KH6MB (Hawaii) calling CQ on 14.004. I responded, only half expecting him to hear my 3W CW signal. He came right back! Wow! My first mobile contact on the KX3 was Hawaii. Nice.
I went on to notch 3 FYBO contacts in the next hour: K7TQ in Idaho, WD7Y in Nevada, and W0DTJ in California. All on 20M. Not too bad for 3W to a dipole 6 feet off the ground.
I also worked Barry, N2BJ in New Lenox, IL on 15M RTTY. Tried PSK31 but had no luck, although the KX3 did an excellent job translating PSK to text for me. A waterfall display is nice, but this rig makes it pretty easy to run PSK without it.
All in all a very productive first outing with the KX3. My plan is to set up my 32 ft. vertical next time to see how it performs at that same location.
Till next time - 73!

The lead story of the February 2013 issue is about an audio filter kit called the Hi-Per-Mite, designed by David Cripe - NM0S - and the 4SQRP Club. While the project was pretty cool itself, what caught my attention was the way the designers created the kit's front panel. They used a slick piece of freeware called Front Design provided by an online service called Front Panel Express.
What I've learned about kit building, especially when the kit provides no enclosure, is that creating the enclosure is no mean feat, especially without proper machine shop tools, like drill presses, brakes, etc. What to do? Front Panel Express offers an excellent option. Simply download their free, and quite sophisticated yet easy to use, software which enables you to design a front panel for your kit (they offer enclosures too).
But, wait, there's more. Once you're done designing the panel (actually at any point along the way) you can check pricing, which makes it a cinch to keep costs in line. Once you're set, you can place your order from right within the application. Very nice!
The front panel I designed for my kit will be made of aluminum. You specify all dimensions (metric or English) and color. You can also specify engraved labels, in choice of fonts and colors! My total cost with shipping: $38.
I placed the order this evening (January 29) and can't wait to see the finished product.
Back in December, I actually obtained enclosures in an attempt to machine my own front panel. But my results were, let's just say, disappointing.
Once I receive the custom-designed panel, I'll post photos so you can see my original work vs. the Front Panel Express product.
In the meantime, check out the K9YA Telegraph and Front Panel Express. I'm glad I did on both counts!
