How to make a "baby" monitor Answered

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.
