1.5 Volt Tracking Transmitter: 10W HF Linear Amplifier: 2 Transistor FM Transmitters: 2 Valve 40m CW Transmitter: 222 MHz Transverter: 2N2222 40 Meter CW / DSB Tranceiver:
30 Meter QRP Transmitter for Morse Code:
4 Transistor Tracking Transmitter:
807 and 1625 Valves: data on vacuum tubes 807 and 1625 used in ham radio transmitters. Describes various pin voltages and different operation modes.
AM / FM / SW Active Antenna: This circuit shows an active antenna that can be used for AM, FM, and shortwave SW. On the shortwave band this active antenna is comparable to a20 to30 foot wire antenna. This circuit uses receivers that use untuned wire antennas, such as inexpensive units and car radios. L1 can be selected for the application
Basic RF Transmitter for PIR Sensors:
Battery operated FM rebroadcast transmitter : Gives you 10 to 20 meters range and runs for months on a single penlight cell.
Compact 20 14 MHz Direct Conversion Receiver:
Design of Brookdale AT Volt Repeater System Exciter: uses a pair of Hamtronics model TA4512-watt narrow-band FM voice transmitters to develop video and audio carriers on439.250 MHz and443.750 MHz
Easy 2 Meter Transmitter: This project is a simple transmitter using only one crystal and will cover 145.00 to 146.00 MHz. The crystal is a 44.9333 MHz crystal for 145.500 receive, as used in the Trio (Kenwood) 2200, PYE, Motorolla, Tait equipment, to name but four. The frequency of the crystal is not critical as almost any other xtal for the 2-meter band will function
Four Transistor Tracking Transmitter:

Micro Power FM Broadcasting Circuits:
One Pot to Control Two Channels:
RF Transmitter, Light Sensing:
T Volt Transmitter: allows you to send video to any television in the house, Poptronix kit circuit
Two Transistor FM Transmitters:
VHF / UHF T Volt Modulator: Elektor January1985
Video / Audio Wireless Transmitter: circuit diagram and project description
Video emitter uses battery power: 08/30/2001 EDN – Design Ideas / The block diagram in Figure 1 shows how to make a cable-free, direct-video system. The system allows users to walk from booth to booth at an exhibition to interview people and to display the interviews in real time on three screens at key locations. You can use the small and simple system each time you need to capture image and sound on the run. .
Video to RF Modulator: This circuit is a RF modulator which can be used for modeling of video signal.

Hi
I want to make a RC toy car but am not able to find any circuit on internet. Could you please send me the required data on my mail. This would me my first wireless project so I want to keep it simple by using only 6 channels for all car movements.
I am looking forward to your reply
Thanks
@Ankur, i have sent your request, please check your inbox

Hello sir i am planning to make an rc helicopter what is the type of transmitter to be used and how can we construct the circuit. i need a circuit of placing these tran’s and receiver’s, can you please give me any information about it.
After reading this article, I just feel that I really need more info. Could you suggest some more resources please?
gini nih
i am pengen bikin suatu rangkaian pengirim dan penerima menggunakan sistem wireless dengan jarak +/ 500m
gimana y? i inun sendiri nih, nyari2 malah pusing
tolong bantuin dunks…
thanks banget sbelumnya
Hi…,saya masih bingung cara merancang rangkaian RF dengan spacifikasi output : 468-600 kHz, 50 Watt, tegangan dapat diatur 0-150 v (mungkin akan disesuaikan dengan beban 50 Watt), dan bentuk gelombang sinusoida.mohon informasi dan masukannya saya tunggu??.Tks
kk tlg kasi tau cara buat aLat walkie talkie sederhana donk..
1 pasang dengan 4 alatnya..
tolongin donk..
kirimin yah ke email saya…
trimakasih banyak…
bagaimana saya bsa dapat diagram2 rangkaian wireless camara koneksi dg handphone? terimakasih
