Talking FOR SALE Sign This Voice Recorder Transmitter is perfect for selling homes, cars, boats, etc. Repeats a message over and over. Just put a sign on your house or car letting people know what station to tune their radio to. Record your voice and transmit it to any FM radio on any FM station (up to 600 ft). Our latest kit combines an FM transmitter and a voice recorder, which provides 8 full minutes of high quality recording with endless loop and playback capabilities. Transmit frequency is easily set using DIP switches, no need for tuning coils or 'tweeking'. There's no frequency drift, your signal is rock solid all the time - just like the commercial stations. Comes with Voice Recorder, FM stereo transmitter, and RCA cables.	Mini FM transmitter - 3 Volt FM Transmitter (bug) The most powerful circuit we've seen that operates on such low voltage (just two AA batteries). A range of 150 to 200ft can be expected and, given a good antenna and FM receiver, over 1 mile can be expected. An external power supply can be used up to 9 volts. Transmits to the FM radio band. Teaches basics of transmitters. Microphone is included. Specifications: L: 1-3/4" W: 3/4" H: 1/2". Requires 2 AA batteries (holder included, not shown in picture). Transmission frequency is user selectable. Transmission can be listened to on any FM radio.	Tru-Match FM Broadcast Antenna Kit - 25 watts max input Weve been besieged with calls asking us where to get a good quality FM Broadcast antenna. Well, we put one of our best RF engineers to the task and came up with this killer of an antenna, we call it the Tru-Match 100. Why Tru-Match? Because matching your antenna to your transmitter is the single most important link in your transmitter set-up - and a good antenna and match is the secret to getting maximum range. When we say match we mean electrical impedance match... if the proper impedances are not maintained between transmitter and antenna, power is reflected back away from the antenna and back into the transmitter! This can cause the final amplifier stage to be damaged, not to mention a spurious signal and lousy range. In real commercial transmitter installations, it is not uncommon for the antenna matching equipment to actually be larger in size than the whole transmitter itself! Our antenna kit consists of rugged pre-cut PVC pipe, antenna radiating elements and of course the proper matching assembly and is fully water-resistant when assembled. The antenna is easily mounted to any standard TV antenna mast like you can find at Radio Shack or K-Mart. A standard 'F' style coax connector is used, so that readily available, low cost RG-59 TV coaxial cable can be used for connection. And we even supply an RCA phono to F Male adapter for easy connection to any transmitter antenna jack. Total length of the antenna is about 5 feet, and it is easily mounted horizontally or vertically polarized - yes, we even explain in the manual the pluses and minuses for each. Maximum input power is now 25 watts. If you're serious, and want a good signal, the TM-100 antenna is for you. You can put this antenna together in less than an evening! Used with the R-FM10A, R-FM25 or R-FM100.	Digital FM Transmitter For Your iPod, MP3 Player, Radio and More Finding the right way to connect your radio, MP3 player, or even a computer, to a stereo system can be time consuming and frustrating. This Digital FM Transmitter lets you send a signal from any audio source to any radio easily, and without wires. Use it to send a satellite radio signal, MP3 audio, and more, to nearby radios around your home or workplace, even in your car. The FM Transmitter is simple to use. Just plug the Transmitter into the headphone jack or line out of any audio device and set the frequency of choice (88-108 MHz). You?re now free to listen to streaming audio from your computer in any room, not just where your computer is. Listen to portable devices without the need for headphones. It has an approximate line-of-sight range of 30'. Walls and metal objects will reduce this range.

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. Then they 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 market! Both are 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. Both the FM30 and FM35WT operate 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! The FM35WT can only be shipped outside the USA, or within the US if accompanied by a signed statement that the unit will be exported. (Note: The end user is responsible for complying with all FCC rules & regulations within the US, or any regulations of their respective governing body). Can be ordered assembled! (Wired and tested-parts soldered to the board, requires small amount of assembly). We have the FM30 and the assembled FM30WT available now.
