The RF Workbench / Mediumwaves amplifier on IRF-s
« on: January 24, 2014, 1805 UTC »
Hello,
I have this generator http://www.hfunderground.com/board/index.php/topic,14811.0.html .
And to make this generator be hear in more distance i need amplifier.
Please post a schematic of amplifier 500-1600kHz band.
I have irf transistors so i need amplifier on IRF-s.
Thanks 73!

Hello,
I'm looking for schematic of AM signal generator(with voice input).
I don't like x-tal - i want schematic on LC(capicator and coil in shield).

Hello,
I'm a young radioamateur. I like a Homemade.
Did this forum supports people who want transmitting - Not listening?
I want to build longwave AM transmitter.
Now i have found amplifier for 137kHz on BC547 and two IRF630.
Please show me a generator for this amplifier. Not on X-Tal(Capacitor and Coil putted into shield)
