My temporary email address is

As soon as I have a new permanent email address it will be given here. I'll keep this address open for a few weeks.

I apologize to the inconvenience. There are an endless number of details involved with closing one business and reorganizing it into another. I'll have it all refined soon. In the mean time, I want to make sure you have a way to reach me.

After operating the RADIO WORKS™ for 30 years, I have decided that it is time to retire. Actually, I'm going to semi-retire and there will be a slight reorganization of the RADIO WORKS. The RADIO WORKS™ will end operations as the RADIO WORKS, Inc. on December 19, 2014. The RADIO WORKS™ web store will not close and will continue to take orders with the current prices being honored. All orders will be processed as soon as I reopen the RADIO WORKS™ as a hobby business on January 1, 2015. The name of the new company is "W4THU RADIO WORKS LLC™" A selection of my most popular antennas, baluns and Line Isolators will be available in the new web store when it opens on January 1st. There will also be some rope and coax available to complete your antenna project. All antennas, baluns, and Line Isolators will be exactly the same quality as it was in the past.

W4THU RADIO WORKS™, LLC will be as a small scale hobby business, though that might change in the near future. However, hobby business or something a bit more elaborate, if you want real, original CAROLINA WINDOM® that's build by the original makers and developers of the CAROLINA WINDOM®, SuperLoop™, and OCFD MAX™, you will be able to order one.

There will be some changes. I will still run a small ad in QST to direct folks to this web site. If you are interested in my future plans for the RADIO WORKS™, drop by this web site occasionally for updates. All current telephone numbers will be disconnected and a new email address will be published. All correspondence will be by email sent to the new email address.

My family thanks 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 new name and I will be taking more time off. Your orders will still be shipped in a timely manner.

Stay tuned,

Jim, W4THU
