R.F. Amplifier KitR.F. Amplifier Kit
Philmore DATAKit # 80-045

A small circuit, using the Mar-6 Amplifier IC, this kit will provide as much as 20 db gain. Connect at receiving antenna input; will boost signals from 1 mHz to 1000mHz; two RF amplifier kits may be cascaded for use at low, broadcast-band frequencies.

Use with Scanners, Ham receivers, SWL receiver etc. You could add a metal case and RF connectors for permanent use. May be used to boost signal for scope or frequency counter as well.

PLL Experimenter Kit
From KHz to 185MHz
Philmore DATAKit # 80-035

An exciting circuit, the PLL Experimenter kit may be used for making a stable AM or FM transmitter, a Signal Generator (from low kHz to about 185mHz), a QRP Ham transmitter, circuit diagrams for all of these are included.

What you get is a very high quality PLL circuit module, with touch-tone style keyboard (to set frequency) and you will have to add the components for the circuits mentioned above. Crystals can be expensive; here is the answer.

Not a beginners kit; intended for the serious experimenter, Hams or very advanced beginner. Operation from 8 to 12V DC; a nine volt battery is ideal. Fine tuning in 10 kHz steps. Extra room on board for added components. This circuit is really worth having!

We suggest you also order a soldering tool kit to make this project. Click here to go to this item (# S540).

PLL Experimenter Kit


FM Audio Transmitter Bug KitFM Audio Transmitter Bug Kit
Philmore DATAKit # 80-070

Temporarily Out of Stock

This is a very popular kit and the most powerful circuit we’ve seen that operates on such low voltage (just two AA cells). A range of 100 meter can be expected and given a good antenna and good conditions, 500 meters is not unusual.

Can be operated on up to about 9 volts. Transmits to the FM radio band. Teaches basics of transmitters. Microphone is included.

FM Telephone Transmitter Kit
Philmore DATAKit # 80-160

Miniature transmitter attaches to the phone line and transmits the conversation. Transmits 200 yards and more in most installations. Tunable to clear spot on the FM band of your radio. Completely parasitic; i.e. uses the power from a telephone line and needs no battery. The circuit might be used to share or record conversation, but not to be used illegally.

FM Telephone Transmitter Kit


Sound Activated FM Transmitter KitSound Activated FM Transmitter Kit
Philmore DATAKit # 80-280

Sound turns on the transmiter, which operates in the FM radio band. A neat way to catch a thief in another room or garage. The volume of sound needed to trigger the circuit is adjustable.

The two stage transmitter has a good range and the circuit powers down unless it "hears" sounds, reactivates with a sound is detected.

Two-Stage FM Transmitter Kit
Philmore DATAKit # 80-320

A powerful little circuit with surprisingly good audio quality. Can transmit up to about 1/2 mile in open country. This is probably the most powerful FM band transmitter that you can legally purchase.

An electret microphone is used to add sensitvity. The kit includes a 4 AA battery holder to run the circuit at six volts, greatest output is 12 volts, but use 9 volts (or less) and a short antenna wire to stay legal.

Two-Stage FM Transmitter Kit


One Chip AM Radio KitOne Chip AM Radio Kit
Philmore DATAKit # 80-630

This is a complete AM radio for the standard broadcast band, most of which is on a single IC. Other components, such as the coils and variable capacitor to make a finished radio are included.

The IC is the RF amp, detector and AGC circuitry. The IC’s output drives a two stage transistor audio amplifer and 3 ohm speaker. Operates on a 9 volt battery.

A good kit for beginners to see and build.  Click Here For Picture Of Soldering Kit # S540.

UHF Remote Radio Controlled
Relays Kit
Philmore DATAKit # 80-082

Two separate relays can be switched via encoded signals transmitted from a keychain size, two-button transmitter (like those used for car alarms and electric car doors).

Push a button and relay toggles "closed" and one more push toggles it "open". Transmit distance is about 120 feet maximum. The receiver requires from 12 to 15 volts DC. The transmitter is supplied assembled and tested complete with its own battery.

Tricky (receiver) parts of the circuit are supplied already-assembled and tested; just plug them in and solder in place. Each relay can handle up to 10 amps @ 120V AC; plenty for numerous applications; control lights, door locks, magic shows etc.
