How to make a "baby" monitor
Hello to All, This is a very mundane request but was wondering if anyone on this list would have the time to help me figure out how to make a monitor for my farm. I have dwarf dairy goats with a llama guardian but with the windows closed now for winter I can't hear if there is a problem. Sometimes they maybe almost 800 feet away. Liese, Piedmont region, NC

Yes, building an AM transmitter (short range) isn't overly hard, and then using an old AM radio tuned to the frequency of the transmitter is very effective and cheaper then many other options.

Or maybe you can refer to the true baby monitor's operating principle.

Get one of these, but add on a larger antenna (and any other mods, like making it plug into the wall instead of being battery powered):
