I want to make a simple transmitter beacon using parts off hand.
I guess the limiting factor is the transistor.
This is what I have:
2n4401
2n3904
pn2222
2n5426
8050
and their pnp cousins
pn4393
J113
tip120
mpsa13
as well as
2n3055
tip31c
tip41c
I also have standard ceramic disk, resistors and diodes, but no crystals.
I can find schematic, but cant figure out what frequencies they make. I have an SDR that goes down to almost DC so that will be my oscilloscope.
