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

January 30, 2015
After operating the RADIO WORKS™ for 30 years, I have decided that it is time to retire. Actually, I'm going to semi-retire. There will be a slight reorganization of the RADIO WORKS. As I write this, it's January 30, 2015 and I've had about six weeks to work on the reorganization. It has been a great deal more difficult than I had anticipated. However, most of the major problems have been solved. I've decided which products will be kept in stock. Some antennas not on that list may be available on special order in the near future.

The RADIO WORKS™ name is not disappearing. You will see it on all my products. W4THU RADIO WORKS LLC is the legal name of the new company, but the "RADIO WORKS™" is the name of the product line and will appear on all of my products. If you want a real, original CAROLINA WINDOM® that's built by the original maker and developer of the CAROLINA WINDOM®, SuperLoop™, and OCFD MAX™, you will be able to order one. The same goes for my line of high quality current baluns and Line Isolators™.

There will be some changes. As I said, I will now operate as a hobby business. That means that I will not be working full time. However, you can expect the same quality service and same quality products. Orders may not be processed as quickly as in the past and your order may take a couple of days longer to arrive. If you order early, this shouldn't be an issue. No one will answer the phone but correspondence will be available through email. I will try to answer email as quickly as possible, but there will be delays. The main thing is that you can still get my most popular products and they will be built to the same quality standards as always. There will be no compromises in the area of quality and performance of my antennas, baluns and Line Isolators™.

I will still run a small ad in QST to direct folks to this web site. The web store, in one form or another, will still stay open.

If you are interested in my future plans for the RADIO WORKS™, drop by this web site occasionally for updates. The only phone number that is still working is 757-484-0140 and it is only a secure answering service. If you want to contact me directly, email me at

I and my family thank everyone who has purchased and used RADIO WORKS™ products over the past 30 years. It's been a fun trip through time. Jean (my wife), Jamie (my son) and I have enjoyed meeting so many RADIO WORKS™ fans personally at the numerous hamfests we've attended over the years. Twenty-Eight of those were Dayton Hamventions®.

I hope to chat with you on the air now that I'll be semi-retired. Remember, the RADIO WORKS™ is still alive and well. It just has a slightly different name.

Stay tuned,

Jim, W4THU
