About RadioSet-GO

The business

RadioSet-GO is a home-based electronics business.

RadioSet-GO is located in Canterbury, NH and has been active since 2010. It is owned and operated by me, Hanz Busch, W1JSB. The business began as a personal challenge to build a QRP (low power) radio (Small Wonder Labs SW-80) and install it in a clear, water-tight box with features geared for outdoor/emergency purposes. (The 80m band was chosen due to NVIS propagation which allows for reliable local/regional communication in the mornings and evenings.) After soldering together the transceiver kit and installing it into the box, I added acorn nuts as capacitive touch key contacts to the front corner of the enclosure. A rechargeable li-ion battery, and LED voltage readout was also included. The operating frequency was known by labeling around the VFO dial. All together, it made for an easy to use Morse code radio package that looked nice and was fun to use!

First RadioSet-GO QRP rig

With the success of the first project, I was eager to build the next one even better - I included a digital dial with LED readout displayed through a clear lexan control panel cut to fit the enclosure opening. Battery voltage was displayed with a side mounted module inside the case. The third version included LCD displays for operating frequency and battery voltage, and an internal speaker with audio amplifier.

My mind flew with ideas while discovering useful technologies online, and ways to improve the design. I sold about a dozen of the SW rigs on eBay, set up a YouTube channel, came up with the name RadioSet-GO and made a website. One of the rigs was published in the June 2011 issue of CQ Magazine.

The last SW transceiver I built and optimized was installed inside a larger Pelican box, with zerobeat tuning indication, variable filtering, analog SWR/PWR indication, and solar charging. When Small Wonder Labs became inactive, I looked into other available QRP transceivers and began working with those. The most popular was the YouKits HB-1B quad band CW rig which I also built into Pelican boxes.

Several custom radios of other types were also built including an MFJ Cub, ATS-3B, MTR3B, Ft. Tuthill, KX1, and KX2.

Owner and operator of RadioSet-GO

What can I say? I've been fascinated with electronics, radios in particular, from a very early age. My first memory with them is handing a toy walkie-talkie to my mother, who was standing in the kitchen at home. I took the other radio and walked up our street (in Littleton, CO) asking her every few steps "can you still hear me?". The range was unimpressive, only a few hundred feet or so and my mother was not that thrilled to be part of any lengthy experiments. Back in my basement room, I knew just what to do - connect one radio to a voice activated tape recorder, that way I could listen to my own transmissions  with location reports later on, and figure out how the signals traveled. With that information I attempted to improve the range by winding copper wire on the existing antennas.

My mother is an artist who encouraged my siblings and me to be creative. My father is scientific minded and introduced me to fascinating things when I was young, such as triboluminescence and electrolysis. The esoteric insight influenced my thinking and sparked imagination. It was my grandfather's house that I grew up in and he was an engineer at Gates Rubber Factory. Naturally there were lots of parts and tools around that I got into, often to the dismay of family members. We had a workroom full of stuff to get creative with. Edison said that "To  invent, you need a good imagination and a pile of junk!" I spent a good deal of my childhood exploring the neighborhood on bicycle searching for electronics that people were throwing away, and disassembling them to see what was inside. With a weed wacker motor I built an automatic door slammer, and many other 'useful' things.

I built a few kits from RadioShack including a broadcast band crystal AM receiver, and a VHF air band receiver. I spent hours lying on my bed tuning into pilots' communications while learning the phonetic alphabet 'Alpha, Bravo, Chalie, Delta, etc..' I bought an analog VHF FM receiver from a thrift store and was able to tune into local HAM, public service, and emergency communications. A digital scanner opened the door to other frequencies with intriguing signals from around the neighborhood. My friends and I experimented with C.B. radios, hand-held, mobile and base stations. An unexpected 'skip' contact of 2,000 miles with only 5 watts of power got me hooked and researching books at the library about radio wave propagation. The various wavelengths, layers of the ionosphere, and solar influences were fascinating to me.

In 9th grade, as part of a choice high school project, I studied for and got my HAM radio license, and was assigned the call sign KB1GIZ. Two years later, with the help and encouragement of another local HAM friend, Jim Cluett, W1PID, I learned Morse code (CW), upgraded to General Class, and got the vanity call W1JSB. Jim took me out hiking with him and introduced me to the joy and magic of portable QRP CW operation - setting up a simple wire antenna into a tree, and communicating thousands of miles with just a few watts of power and a tiny battery powered Morse transceiver.

My 'regular' day job is in assembly and test at Spinnaker Contract Manufacturing, in Tilton, NH. It is largely due to my radio projects that I got the amazing job. I specialize in downlink tuning and uplink gain adjusting small-cell network (cellphone) repeater equipment, as well as building optical power meters, often used by telecom field workers. I have IPC-A-610 (Acceptability of Electronic Assemblies) & 7711/21 (Rework and Repair) training and certification through the company. Prior to working at Spinnaker I had a wide variety of jobs including landscaping, cold glass sculpting, and as a school bus driver.

A few other hobbies and interests of mine include QRQ (high speed Morse code) photography, hiking, landscaping, gardening, and alternative energy. My wife and I have an almost 2 year old son who is already entirely obsessed with radios and Morse code. We have built a small farm and have an abundance of pets. With all of this, we stay quite busy. Thanks for visiting my website and taking the time to read this. I hope to meet you on the air sometime!



...I can't wait to show this work of yours to everyone! The sound alone is many steps above what it was. The workmanship is so high quality, and the extra features will be so useful!

As one of your first customers for the RadioSetGo KX2 custom retrofit, I just wanted to express my deep appreciation to you for the quality of your workmanship. It has become the envy of my radio club and has performed above expectations in the field. I am not just pleased with your fine craftsmanship, but the thought that went into the design and functionality of the controls shows an appreciation for ergonomics and simplicity.

I ordered a keycap keyer from you in March. I have had lots of fun experimenting with it. I have many traditional shack and portable paddles, but was looking for something very portable and rugged for my QRP travel rigs. I have been a CW op for 66 years and use all the iambic B features on my paddles. I was surprised with only a few hours of practice I felt comfortable with the touch key at over 20 WPM. ...Hopefully it will work out at 35 + WPM when I get some practice time. Thanks again for a great product.
