Expanded Spectrum Systems will be filling this web site with projects that will spark your interest in electronics and Amateur Radio. Combined with some basic support for projects already in use ESS will integrate today's ideas with the new and exciting technology of tomorrow. ESS is looking for new ideas from our clients. Have an idea you think someone else would like? Contact ESS with your original electronic projects for review. It may just be the item we are looking for.

The Freakin' Beacon is taking on another roll. Requests have been coming in for a way to have a GPS synchronized beacon. The reason to have a GPS synchronized beacon is the ability to put more than one beacon on the same frequency like the international beacons. A group of beacons could be centralized on one frequency to eliminate tuning around to find several beacons in different locations. Listen on 28250 MHz for the first of the synchronized beacons on the air. These are but a few of the applications. It has been our experience that when we put a new product on the market we receive lots of requests for applications that we never considered. Go to the Freakin' Beacon page to get the introduction to this new application. If you already own and FB1 or FB2 and want to give this a try you can download the PIC code from the Freakin' Beacon page.
You can get involved in the conversations about synchronized beacons on a mailing group at http://fernblatt.net/mailman/listinfo/beaconsynch_fernblatt.net Take a look at what is going on.
You can always send an email directly to ESS with your questions and we will answer them as soon as possible.

Beacons high in the sky? The Freakin' Beacon might make a great beacon controller for your next balloon or rocket experiment. FB1 weighs in at 17 grams and is 2.2" x 1.75" nominal.

My apologies for not regularly checking the email links to see if they are working properly. Thanks again for all your orders, Rich - N4ESS

01/11/2006 - I would like to thank everyone for visiting our site. The article, "Smoother tuning for the HW-8 transceiver" by Bill Coleman, N4ES, has been downloaded by our visitors more times than it would have been seen if it had been published in a magazine. Thank you for your patronage. If you have written an article pertaining to Amateur Radio and would like it posted in our articles section for public viewing please submit a copy to us for review. These must be original articles of your own. Thanks again, Rich - N4ESS

12/15/2005 - FLASH CRYSTAL !!! What is the Flash Crystal you ask? The Flash Crystal has been around for over a year now and several of them are in use around the world. The projects are varied from test lab applications to communications down converters. Time to do some reading. Click on the Flash Crystal page and download the manual in .pdf format. Here is the clean stable RF source that you have been needing for that special project. It is small, 2"x2", lightweight, ready to use when you get it.

07/05/2005 - The Freakin' Beacon just became a lot easier to program. It was easy to begin with but now it is just plain simple. Peter Jennings, VE3SUN, has put together a simple and easy approach to getting the message you want with little more than just than a few keystrokes. The link is on the link page and another on the Freakin' Beacon page. Thanks Peter.

04/01/2005 - No, it is not an April Fools joke. Synchronized Beacons. That is one of the next projects going at ESS. The Freakin' Beacon will get a new task. Listen on 28250 for the Synced beacons.

02/06/2005 - SPECIAL ORDER CRYSTALS. I have received several requests for crystal orders on special frequencies not usually offered on our web site. I will begin accepting requests for quotes for HC49 crystals on special frequencies. The minimum order will be 100 crystals at a price I'm sure will be pleasing.
