Bill and all,
There are a couple of gremlins you need to be aware of with the AM-25.
First, take the Ramsey supplied wall wart and see how far you can throw it. If you have a shotgun, before you throw it you can yell, “PULL!” Before you shoot, rememeber to swing through the target.
Second, use a regulated and filtered ~12volt DC power supply to power your transmitter.
Third, make sure the transmitter has a good earth ground.
Fourth, I used shielded audio wire from the audio device to the transmitter audio input. Make sure you connect the ground/shield lead only at the feed input end to ground.
And finally, check your audio device (cd player, computer, mixer, ect.) to make sure the audio levels have been adjusted for the least noise of any kind.
A word to the wise: If your AM-25 continues to hum, do what I did, teach it the words to the song.
