Title: Help with translation from Russian plaese!
Post by: imperator on September 20, 2011, 05:36:45 am
Hi all! Can someone help me with understanding the topic from russian radiopirate forum? The topic is about 50W FM transmitter http://vrtp.ru/index.php?showtopic=18252&st=0
and the circuit seems to be designed well. Thank you!

Head a quick browse and from what I can see the first part they are discussing the design, its output power, the devices used and power supply requirements. The amplifier design uses the rd06 & 70 devices, for another good design with them search 'free radio Berkleyb(frb) 70 Watt instructions/ manual' something like that. Its an American design, very similar.

Good luck

It's a transmitter that uses si4711 with amplifier rd15 + rd70 (not rd06, on rd15 goes 5 volts)
