Welcome to my projects page
Here are a few of my projects I have done in the shack, by now you should see that I like making gizmo's that are very useful. Some projects such as un-un's and baluns I have made from
sheer necessity, since I had to run a fixed portable station. I had to work so much harder to get a signal out at my last location ie. lived in an apartment up in NYC. I think I did fairly well in accomplishing this . I'm involved in QRP operation and backpacking when I can, but now and then I will run a whopping 100 watts from my exciters. I hope I can give you just a little inspiration on doing some projects yourself. Some projects that don't show up here are computer projects that I'm always whipping up. I'm into software and internet programing and design, which includes graphic design. Maybe I might fine enough room to display a few computer related projects here.
New 2010 projects my version of the ibox
This is my new compact microphone line leveler ,I had just one more audio transformer left in the junkbox . it was a tight fit, but enough for good seperation
Looks a bit messy, since the wire is a llittle longer than needed, but it works well. I used a midcom 671-8056 1 to 1 600 OHMS FREQUENCY RESPONSE: +/- 0.25dB @ 200Hz. – 4KHz transformer that I pulled out of a old 5600bps modem.
I replaced R2 with a fix metal film resistor drop the line Level to about 20db ixed.

UN-UN'S and Baluns
The unun should find some important applications. Until recently, they have been literally impossible 
to obtain. But now they can be designed to match 50-ohm cable to loads as small as 3.125 ohms and as high as 800 ohms (both unbalanced loads). They can come in low-power and high-power versions as well as multimatch designs. An important application for ununs is to match 50-ohm cable to the input impedance of ground-fed antennas such as verticals, slopers, inverted L's and towers performing as verticals.Since ground losses play a large role with these systems, a knowledge of the input impedance of the antenna as well as the
ground loss is important in determining the optimum impedance ratio. The low-power multimatch unun should find use in the operating room when an unfavorable impedance is presented to the transceiver. Also, a high impedance, multimatch unun can be easily designed to match 50-ohm cable to the input impedance of Beverage antennas. It should also be pointed out that ununs can be employed in series with baluns to provide a host of wideband baluns and ununs with ratios which have been previously unattainable.
Small L Tuner project
This is a small tuner project yet
to be finsished this is the prototype of the tuner. Great for portable work or in the shack. This L tuner can also be used in emergency conditions. This little tuner works great for portable short verticals.
Some finished projects
Here are a few projects in my shack, they include a 4.1 un-un a microphone balanced to unbalanced convertion box
with ptt. You can hook up any balanced type microphone to you rig by making up the proper cable, and have ptt abilities. The large tupperware container houses a sg-239 auto coupler witch protects it from the wx.
SG-239 COUPLER project
This is my sgc-239 tuner project. I have made a container to provided a watertight container for the tuner fo
r outside use. the SG-239 seems best designed for, portable use such as: Backpacking, camping, light-duty work away from home, creative antenna applications. I used a common tupperware container to fit this job. Here are some good links that have Tutorials and some great ideas. The SG-239 - Making a Waterproof Case by David H. Hatch - N9ZRT and MM0ANT's SG-239 Projecs.
