Hello Eugene! I am responding to your letter dated November 29, 2004, then written by Eugene Palenock to All, and then it was 15:57:48 on the clock. EP> Are there complete transmitter modules for sale for creative applications? Yes. EP> Well, for example, build it into a mousetrap (otherwise I’m tired of going to check if there is a mouse EP> or not)... EP> Well, or generally any similar transmitters that do not require licenses RRFQ1-XXX-Y Superheterodyne radio receiver with frequency shift keying and quartz generator Main Features RRFQ1-XXX - superheterodyne data receiver with frequency shift keying, with phase-locked frequency synthesizer (PLL) and crystal oscillator Noise reduction function is implemented to reduce the output noise, when there are no working transmitters Received frequencies: 315/433.92/868.35 MHz Intermediate frequency: 10.7 MHz Typical sensitivity: -102dBm Current consumption: 5.7 mA (typ.) XXX: operating frequency specified by the customer (315; 433.92; 868.35 MHz) RTFQ1-XXX Radio transmitter with frequency shift keying, quartz oscillator and external antenna Main Features RTFQ1-XXX is a hybrid circuit that allows you to implement full radio transmitter, supplemented with coding scheme Thanks to thick film hybrid technology they show stableelectric characteristics XXX: operating frequency (315; 433.92; 868.35 MHz) As I understand from the descriptions, it is best to work at a frequency of 433, no permission required there. (At this frequency, by the way, they work car radio alarms). I'm going to play with these chips myself someday, I'll connect the receiver and a transmitter for RS-232 input and output of the microcontroller. I will make a connection diagram almost the same as drawn on the site http://www.roboclub.ru/ Chips cost somewhere in the range of 300-400 rubles. every. Indoors they will penetrate 100 meters, outside - up to 400. All the best, Alexander.

And how is your nothing, Eugene! I am writing to you from a burning tank...
