DC Electronics - Kits
We now have two PLL Tuned FM STEREO TRANSMITTER
KITS
PLL-SFM for $79.95 and the all new SFM-3 at $129.95---
PLL Experimenter Packages
Includes experimenter board with keypad and prototyping areas, MC145170 or MC145193 PLL
chip, programmed PIC and support components - just add oscillator, audio & rf amp to build an
FM transmitter at your choice of frequency band. Can also be used to build RF signal generators,
recievers or AM transmitter/receiver. Go to either PLL App
Note or PLL Kits for more details.FM Stereo Transmitters and Accessories
The all new SFM-3 at $129.95 is our top of the line kit, loaded with features and performance found nowhere else - fine tuning in 5KHz steps, LCD readout, direct keypad tuning, eeprom memory and more. The same great performance but with fewer features can be found in the PLL-SFM at $79.95, which as far as we know is the lowest priced FM Stereo transmitter kit on the market with PLL tuning. For the limited budget, we have two great sounding entry level kits at $39.95. These both do a good job but for best stability must be kept in a room with a pretty constant temperature. We used some unique design features for easy tuning and improved stability in an entry level kit.Any of these models will do a fine job transmitting around the house and yard - Listen to your favorite MP3 files or internet broadcasts without being chained to the computer, or transmit any other stereo source (line level signals) such as satellite TV, tape deck, CD player etc. for listening on a normal FM radio elsewhere in the house or out by the pool.
More RF Kits
Seven more RF kits here, including a selection of low cost "wireless microphone" types for under $15.00. Check out the new VTFM, the easiest tuning kit in this class. We also have a really handy experimenter board and data packet bundled with the NE602 double balanced mixer.Audio Kits
Here is our selection of audio amplifier kits from 1 watt mono to multiple channels at 50 watts rms per channel. We also have a tone-volume-balance control kit based on TDA1524 and a hot experimenter package for LM3886. All are available assembled and tested except the LM3886 Experimenter.Power Supply Kits
Choose from fixed or variable voltages, mA to several Amps, single or dual. Among our selection are a variable voltage switched mode supply for high-powered car audio. This one is really hot, easily adjusted from a minimum of + 24V to a maximum + 35V output rails starting with a nominal 12VDC. As supplied it will crank out over 200 watts continuous power, and has room to add more FETs to go to 300+ watts.Seven More Kits - Various Types
These are the ones that don't fit in the categories above, though many wind up blinking one or more LEDs for a variety of reasons...
Construction Zone Follows
More kits will be added from time to time as we get them
developed. We always seem to have more on the drawing board than
we have time to complete. ...
