✔ Simple connection to your MP3 player, stereo, or computer!<br />
✔ Built-in telescoping whip or external antenna operation<br />
Designed to be the heart of a basic FM transmitting system makes the FM25B a solid performer and very economical to build and<br />
operate. Just plug in the audio from your MP3 player, CD player, DVD, computer, tape deck, VCR or even a TV and broadcast it on any<br />
frequency in the standard FM broadcast band. The sound quality and stereo separation of this little transmitter will keep the pickiest<br />
audiophile happy. This unit has many uses! Broadcast your favorite music around your house and yard. Use it to play DJ for your<br />
friends. Farmers, broadcast to your tractors in the fields. Used in conjunction with our BS2 Digital Voice recorder makes the FM25B an<br />
ideal event broadcaster. Broadcast school events to parents picking up their children from school. Broadcast important messages to a<br />
small community. The applications for this kit are limited only by your imagination!<br />
The FM25B brings stereo line level audio into the unit through a 3.5mm stereo phone jack. A loop out is provided at the input for<br />
monitoring. The unit features a PIC microprocessor for easy frequency programming through board mounted DIP switches. The<br />
transmit frequency is Phase Locked Loop (PLL) controlled for unparalleled stability making frequency drift a thing of the past, extremely critical for digital tuners. The RF output level<br />
is adjustable from 5uW to 25 mW via a potentiometer. Use the built-in whip antenna or use an external antenna with the standard "F" external antenna connector on the rear panel.<br />
Just plug it in and you're on the air. The unit requires 12 VDC @ 100mA to operate. Kit comes with: matching case set, whip antenna, 110VAC power adapter, and audio patch cable.<br />
Case size 5"W x 1½"H x 5¼"D. (Note: The FM25B is a do-it-yourself learning kit that you assemble. Please remember that the end user is responsible for complying with all FCC<br />
rules & regulations within the US, or any regulations of their respective governing body in regards to the application and use of the FM25B).<br />

Basics Of FM<br />
Transmitters!<br />
Here is a great entry-level kit that will teach the basics of FM Broadcast transmission while finding many uses around the home or<br />
dorm room. The FM10C has plenty of power to cover your home, backyard, or city block. Our manual goes into great detail outlining<br />
all the aspects of antennas, transmitting range and FCC rules and regulations.<br />
KIT<br />
You'll be amazed at the exceptional audio quality of the FM10C. Tunes through the entire 88-108MHz band in three separate ranges with<br />
a tuned LC circuit. Re-broadcast your favorite music commercial-free with the dynamic range the musician intended, and without all that nasty<br />
compression the big boys use to make their station sound louder than the competition. Runs on a standard 9V battery (not included), external<br />
power from 5 to 20 VDC, or an optional 120 VAC adapter. Includes the matching case & knob set for a professional finished look. Case size 5”W x 1½”H<br />
x 5¼”D. (Note: The FM10C is a do-it-yourself learning kit that you assemble. Please remember that the end user is responsible for complying with all FCC<br />
rules & regulations within the US, or any regulations of their respective governing body in regards to the application and use of the FM10C).<br />

Professional Synthesized AM Transmitter<br />
✔ Fully synthesized, no frequency drift!<br />
✔ Ideal for schools<br />
✔ Microprocessor controlled!<br />
✔ Strappable for higher power output where regulations permit<br />
✔ Includes AC power adapter and case set<br />
The AM25 is not your ordinary hobbyist AM transmitter! The AM broadcast band is quite alive and well, and is still considered the<br />
home of talk radio. For years the AM band has been a popular place for community broadcasts, in-home broadcasts, and other local<br />
information broadcasts. Now you can have a professional synthesized AM transmitter at the cost of a hobby unit!<br />
The AM25 operates anywhere within the standard AM broadcast band, and is easily set to any clear channel in your area. The design is similar to<br />
that of a commercial radio transmitter, so while you build it you’ll learn how the “big guys” operate. It is widely used by schools - standard output is<br />
100mW with range up to ¼ mile and is jumper settable for higher output where regulations allow. There is no tuning or tweaking involved with the AM25. The PLL synthesized frequency<br />
is easily set with dip-switches and is rock solid without any drift, just like our FM25B. This is critical for any digital radio or tuner. The transmitter accepts line level input from<br />
any audio source including CD players, tape decks, computers, etc. Includes matching case & knob set and 110VAC power supply. Case measures 5”W x 1½”H x 5¼”D. (Note: The<br />
AM25B is a do-it-yourself learning kit that you assemble. Please remember that the end user is responsible for complying with all FCC rules & regulations within the US, or any regulations<br />
of their respective governing body in regards to the application and use of the AM25).<br />

#1 Scouting Project<br />
For Years<br />
The AM1 is a great first kit and a fine low power AM broadcaster for the hobbyist on a budget. It’s a great way to learn the<br />
basics of AM broadcast technology, not to mention basic soldering and component identification (if you’re a beginner!). The<br />
transmitter can be tuned to broadcast anywhere in the AM band (550 to 1600 kHz).<br />
Setting frequency is simple - tune a nearby AM radio to the desired frequency, then adjust the AM1 coil to match the radio. With 100 mW of output<br />
power, range can be up to ¼ mile. Connect any line level audio source from your CD player, tape deck, or mic mixer to the RCA input on the rear<br />
panel of the AM1C and you’ll be on the air. It’s that simple! The AM1 has been used by Scout camps, churches, schools, and other organizations to provide easy,<br />
low cost communications. Includes the matching case and knob set shown. Measures 5”W x 1½”H x 5¼”D. (Note: The AM1C is a do-it-yourself learning kit that you assemble.<br />
Please remember that the end user is responsible for complying with all FCC rules & regulations within the US, or any regulations of their respective governing body in regards to<br />
the application and use of the AM1C).<br />
