Radio Shack 1.5 VDC AAA FM transmitter
In 2007, we tried using an old Radio Shack 1.5 VDC AAA FM transmitter. This type of transmitter was used for folks that wanted to listen to their CD player in a vehicle that only had an FM radio. We quickly found that the range on such a device was only intended to transmit about 10 or 15 feet. Fortunately, we were able to assemble a speaker in the yard. The computer that ran the show was housed in the garage. We ran an 1/8" stereo audio cable from the computer to a stereo to mono adapter, to a mono RCA adapter, and then to a 1/4" mono male and into an amplifier. My father-in-law had given us a coil of old SPT lamp cord that we used to run from the amplifier out to a bush in the yard. My father had loaned us an old megaphone-like speaker that we placed in that bush. We put the amplifier on an old dial timer so that the audio turned off at about quarter to 10. We also carefully monitored the audio level so as to prevent sending our neighbors through the roof.
