At the RADIO WORKS, Ham Radio is a Contact Sport!™
DX Made Easy™

January 18, 2016
Be sure to visit this web site and my web store frequently during the next few months. There are many changes in the works.
It has been one year since I announced that I was entering semi-retirement. I have yet to experience the retirement part, but that will probably change soon. The surprise was that my plans for just working a couple of days a week have now turned into a full-time situation. Instead of business falling off, the RADIO WORKS™ is doing better than it did in 2015. I'm not complaining. I'm thankful that folks still want my antennas, baluns, and Line Isolators. To that end, my XYL, Jean, and I are now putting in all the effort required to get orders out to our customers in a timely manner. Fortunately, I still have Brad building my matching units, baluns, and Line Isolators. Judy is still building my antennas. That means that you don't get a pitiful, poorly made knock off. You get the full performance of a genuine CAROLINA WINDOM® or SuperLoop™. You also get the same quality and long life you expect from RADIO WORKS products.

I want to thank all of you who have been so supportive and encouraging over the past year and more than that, over the past thirty one years.


1. All orders must be placed through my web store. I cannot take telephone orders. That keeps things organized and leaves a permanent paper trail. It is also the only efficient way I can handle credit cards.

2. I can no longer accept orders outside of the U.S.A.
First, it is impossible for me to process credit cards with foreign addresses. It's a security issue. I have to have a U.S. five digit zip code for the billing address of the credit card I'm processing when I enter a credit card manually.

3. If you have visited the RADIO WORKS web site in the past and revisit my site , you may not get the current web site changes. Be sure to click the "reload" button in your browser to get the current version of the RADIO WORKS' web site. Most browsers will archive previously visited web sites and keep a copy on your computer. If they do, you may get an old version my my site. If you are reading this news update dated January 18, 2016, you have the latest version of the RADIO WORKS™ web site.

4. I will try to keep the web store inventory as correct as possible. Thus, if you see an “out of stock” message when you press an “add to cart” button, that means what it says. The product is currently out of stock, but I'll make products listed as out of stock available as soon as they can be built.

5. I want to say something about high shipping charges. The problem is that the first few pounds shipped cost far more per pound than the last few pounds. For example, shipping a single balun or Line Isolator can generate shipping charges that are a large portion of the price of the product. However, shipping an antenna, rope, and other heavy accessories considerably reduces the price per pound. There is nothing I can do about that. Most of the cost for UPS or the Postal Service is in the processing and delivery of the package. That is fixed cost. When the delivery driver brings a package weighing one pound or ten pounds, most of the effort and cost is just getting the package to your door.

Important Advice

Some orders take longer for me to process than others. Transit time will usually be 5 or more business days on orders going to the west coast. Please take into account that I'm doing the best I can to get your order to you as quickly as possible, but if you have a critical delivery date, please place your order two or three weeks in advance. Remember, it's just Jean and I processing your orders. There is no "staff" any longer.

There will be other changes designed to improve efficiency, minimize errors and take some of the load off of Jean and me. I really appreciate those of you who have endured the delays with your patience and understanding.

Stay tuned,

Jim, W4THU

New Product News

I have added a few products in a list below and am listing available replacement parts.


There will soon be a sale area where I am selling off some old stock items that used to be available in my catalogs. The quantity is limited. As I find them and get them organized, I'll put them on the list. You will get good SALE prices on these items.

I will also be selling some of my personal equipment and parts. I can't promise when I'll have these on my web site, but I'm planning a new shack renovation, so I'll come across lots of goodies I no longer need. Drop by often to see what's new.

I'll try to have some sale items up soon.
