Includes line level monitor outputs, improved stereo separation and audio clarity!
For nearly a decade Ramsey has been the leader in hobbyist FM radio transmitters. First they came out with the low cost FM10, the tunable FM transmitter that has set records as the most popular school, scouting, and first time hobbyist kit. Then Ramsey introduced the world famous FM25 series of FM transmitters. They 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 Ramsey introduced the 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 FM100B continues to be our #1 selling transmitter! There are two reasons why.... reliability and unmatched product support.
NOW INCREASED PERFORMANCE WITHOUT THE FRILLS
Ramsey's RF engineers took it as a challenge and designed not one, but TWO transmitters! The FM30B is designed using through-hole technology and components, with a 25mW output very similar to our FM25B and FM100B series kits. Then they redesigned their brand-new design using ultra reliable surface mount technology (SMT) for a very special factory assembled and tested FM30B version, with a 25mW output.
The FM30B 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, the 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 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. Power input is 13.8 to 16VDC and includes a 15VDC plug in power supply. The stylish metal case measures 5.55"W x 6.45"D x 1.5"H.
One look at the inside of the FM30B and you will see we're serious about professional performance. Not just another kit hand assembled with the typical limitations and tolerances of such through hole assembly, it was designed from the ground up utilizing surface mount technology. What does this mean to the professional broadcaster? Two words: performance and reliability! With SMT there is no room for error, and precision has a new meaning. All components are machine placed and soldered to assure absolute repeatability of guaranteed specifications, just like the commercial transmitters costing tens of thousands of dollars. Along with SMT construction you will find microstrip PCB inductors and stubs eliminating mechanical and coaxial coils as well as tuning requirements. RF output power is a conservative and cool running 250mW, and is front panel variable throughout the entire range of 0-1.0W continuous duty. Audio pre-emphasis is available for either 75uS.
Unit has a sharp looking metal cabinet, external whip antenna and 110-240 VAC power supply which is compatible with most power systems worldwide.
