THE LEGACY CONTINUES!
For nearly a decade we have been the leader in hobbyist FM radio transmitters. First we came out with our low cost FM10, the tunable FM transmitter that has set records as the most popular school, scouting, and first time hobbyist kit. Then we introduced the world famous FM25 series of FM transmitters. We took the basic concept of the tunable FM10, made it synthesized for rock solid and stable operation and gave it the features and performance that made it THE LEADER in low cost FM stereo transmitters. From there we introduced our FM100 series Super Pro FM Stereo Radio Station. We took the exceptional circuitry of the FM25 and built a stand-alone "radio station" around it, complete with microphone and line level audio mixers, digital control and display of operating frequency, higher RF power output options, and put it all in a professional case. To date, the FM100 series continue to be our #1 selling products!

NOW FOR 2005...
Introducing our new FM30 series transmitters! How could we make history better? First, we listened to thousands of our customers that loved the stability of the PLL synthesized FM25 series but wanted easy to change front panel control of the operating frequency and wanted to know what frequency they were transmitting on. They also wanted the capability of controlling the audio levels at the transmitter rather than changing the input levels. We thought those were very legitimate requests, and our response was to move up to the FM100 series. "But I don't need an audio mixer, I don't need all that fancy stuff built-in, I just need a small transmitter I can afford"! Here you go, designed from the ground up...the FM30 series!

The FM30 is designed using through-hole technology and components and is available only as a do-it-yourself kit, with a 25mW output very similar to our FM25 series.

The FM30 is designed around an RF tight vinyl clad metal enclosure for noise free and interference free operation. All settings are done without taking the cover off! Enter the setup mode from the front panel and step through the menu to make all of your adjustments. A two line LCD display shows you all the settings! In addition to the LCD display, a front panel LED indicates the PLL lock so you know you are transmitting. Besides frequency selection, front panel control and display gives you 256 steps of audio volume (left and right combined) as well as RF output power. A separate balance setting compensates for left/right differences in audio level. In addition to settings, the LCD display shows you "Quality of Signal" to help you set your levels for optimum sound quality. And of course, all settings are stored in the non-volatile memory for future use!

The design includes EMI filters on line level audio and power inputs, and a state of the art microstrip PCB inductor to reduce microphonics for the ultimate in alignment free operation. RF output is through a professional well shielded rear panel BNC connector for a perfect antenna match. Standard RCA connectors are used for left and right line level audio inputs.

The FM30 operates on a 13.8 to 16VDC and include a 15VDC plug in power supply. The stylish metal case measures 5.55"W x 6.45"D x 1.5"H and is a perfect match with your computer to broadcast your music files throughout your house. If you're looking for a super performer without all the features of our FM100 series transmitters, the new FM30 is for you!
