I'm looking to build a simple from parts I have off hand:
Transistors, resistors, diodes, disk caps hand wound air inductors.
Parts I dont have: Crystals or timer chips. I know this can be done but I'm legally blind and having a very hard time finding a schematic online. I'm going to use an SDR to receive and because I have just plastic package through hole transistors its not going to be high power so I'm not worried about interfering with anyone's radio. Its to place a few of them around in a rural radio quiet area and play hind and go seek, to test different antennas. Higher frequency would be better as it makes both antennas smaller.
I have an arduino that I could use to generate the tone or short morse signal.
