Title: I'm searching for schematic diagram... Post by: IW3FZQ on August 18, 2009, 02:22:00 PM Hello all! I'm new to this forum. I'm searching for a schematic diagram of a vacuum tube AM transmitter for 160 meter or high portion of medium wave. The only one schematic diagram I have, uses a couple of octal tubes, without output filter and with a L-C oscillator and it has a very low power, only few milliwatts! It will be a good thing if its power is around some Watts and a crystal controlled oscillator.
Thanks ! Enrico, IW3FZQ Title: Re: I'm searching for schematic diagram... Post by: KB2WIG on August 18, 2009, 03:42:16 PM Enrico,
Here's a link for a transmitter, http://www.amwindow.org/tech/htm/813/813.htm and one with a little less power, http://www.amwindow.org/tech/htm/wb9eckseriesmod.htm Welcome aboard Amfone, klc Title: Re: I'm searching for schematic diagram...

The schematic with 4x813 is too ambitious but the second link is well done! .... and I'm owner of all four tubes! 73 de Enrico, IW3FZQ |
