Digital Controlled FM Stereo Transmitter
For nearly a decade we’ve been the leader in hobbyist FM radio transmitters. We told our engineers we wanted
a new technology transmitter that would provide FM100 series quality without the advanced mixer features.
They took it as a challenge and designed not one, but TWO transmitters! The FM30 is designed using through-hole technology and components and is available only as a do-it-yourself kit with a 25m W output very similar to
our FM25 series. Then the engineers redesigned their brand-new design using surface mount technology (SMT)
for a very special factory assembled and tested FM35WT version with 1W output for our export only market!
All settings can be changed 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 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 non-volatile memory for future use! Both the FM30 and FM35WT
operate on 13. 8 to 16VDC and include a 15VDC plug-in power supply. The stylish black metal case measures
5. 55"W x 6. 45"D x 1.5"H. Call for FM35BWT export information. (Note: After assembly of this do-it-yourself hobby
kit, the user is responsible for complying with all FCC rules & regulations within the US, or any regulations of their respective governing body. FM35BWT is for export use and can only be shipped to locations outside the continental US or valid
APO/FPO addresses or valid customs brokers for end delivery outside the continental US.)
