For more than 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. (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.)
