WTR1605L LTE/WCDMA/GSM Transceiver + GPS
This is an experimental generator based on the IRF510 transistor for short waves. Experimental because the frequency of this generator is unstable. I received the signal of this generator at…
From a long wire and a matching device, you can make a Fuchs antenna for short waves to conduct radio communications over very long distances This antenna works well at…
A simple single-sideband radio transmitter with which you can carry out radio communications over very long distances. The transmitter is built on the principle of phase shift. A generator is…
Today, KIT kits are sold on well-known websites under the name "USB linear power amplifier 70 watts for a frequency of 3.5-30 MHz".The power may still indicate 50 watts.I bought…
With this radio transmitter, you will be able to conduct radio communication at a great distance.Amplitude modulation, output power of about 5 watts,power supply of 13.5 volts, current consumption of…
This radio transmitter is designed to operate at a frequency of 433MHz.When powered by 9 Volts, the range is more than 500 meters (300 meters is a sure reception).Reception was…
With this simple radio transmitter, you can go on the air at a frequency of 27 MHz.The modulation is amplitude, the output power at a load of 50 ohms is…
There are microcircuits in cell phones that amplify a weak high-frequency signal by power, and one of these microcircuits is the RF3140.This microcircuit was used in old cell phones, today…
Somewhere in the early 60s, one device was patented in the USA, which is a radio transmitter that does not require the usual power source.And it feeds on the energy…
With this simple radio microphone, you can transmit sound from the microphone to a distance of 100-150 meters and receive a signal to a radio receiver with an FM band.This…
With this simple amplitude modulated transmitter for long waves, you can broadcast your transmissions over a short distance.The hurdy-gurdy operates at a frequency of approximately 160-180 kHz, which falls into…
