Good morning, my name is Eric (KE2DPY). I'm an avid radio enthusiast, mostly tube gear and building my own stuff (including a high level plate modulated transmitter) but with a huge interest in civil defense and conelrad. I'm trying to find the 640 kc and 1240 KC "conelrad kit" that you could buy as an option for broadcast transmitters so far to no avail. If anyone has any idea where I could find them and or has them that would be great! Hope you all have a great day!
