I am retiring and the time is NOW!

The countdown continues and retirement is only a very few days away.

It has been over three years since I announced my retirement. That was on December 31, 2014. However, retirement never happened, and I entered into "semi-retirement". As I have said on many occasions, I have yet to experience the retirement part, but that is going to change soon.

While it is definitely going to happen, the good news is that I have some inventory of my most popular products. This will be a "last opportunity" to get that CAROLINA WINDOM® or SuperLoop™ that you have always wanted. I know that some of you may want to get a spare in case something happens or your plans change. Once all the available stock of antennas, baluns, Line Isolators are sold, that will be it. There should be enough antennas and other RADIO WORKS™ products to last for a few more months, but that all depends on the demand and demand has been high. The numbers are limited, so don't miss out on this opportunity. Remember that Judy and Brad, KQ4IX, are still making the products. Judy has been building my antennas for nearly 30 years, and Brad builds all the baluns, Line Isolators, matching units and such and has been doing that for at least 20 years. This means that you don't get a pitiful, poorly made knock off that doesn't perform well. 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. 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. Without Jean's continued help and support these past two years would not have been possible. I want to thank all of you who have been so supportive and encouraging over the past couple of years and more than that, over the past thirty-two years. .

Remember that it's just Jean and I processing your orders. There is no longer any "staff." I normally have only two shipping days each week. So, please plan accordingly.

Stay tuned, Jim, W4THU


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 way I can handle credit cards.

2. I can no longer accept orders outside of the U.S.A.
I must process all orders through my web store at and as a security measure, you must have a U.S. five digit zip code for the billing address of the credit card being processed. It's a security issue.

3. If you have visited the RADIO WORKS web site in the past and later 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 it should be dated April 25, 2017, which means you have the latest version of the RADIO WORKS™ web site.
It is very important as to keep up to date with the the latest news. Also, there will be some special sales that might tempt you!

4. I will try to keep the web store inventory as up-to-date as possible. Thus, if you see an “out of stock” message when you press an “add to cart” button, that means the product is out of stock. I'll make products listed as out of stock available as soon as they can be built. When a product is no longer available, I'll get it off the web store's product index as quickly as possible.

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 with 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 a 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.

What I will do and have been doing in cases where the shipping charges are over estimated by my web store is to recalculate the shipping cost manually and give you a refund for the difference. This will be indicated on your sales receipt if it applies.

Important Advice

Some orders take longer to arrive or 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. 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.

Stay tuned,

Jim, W4THU
