Q: Someone mentioned the frequency fluctuates. Can you lock in a frequency or does it always fluctuate?

My unit does "waver" at about 2 Hz around the set center frequency. When in the audible region it sounds like a sound effect in an old TV show. The "wavering" is definitely an intentional design feature, not a problem with the circuitry. I watched the output on an oscilloscope and the wavering continues even as the frequency moves to the highest end of the frequency range. For any use other than a pure signal generator, like trying to drive away critters, the wavering is probably a good design feature.

Q: If I use this device + piezo loudspeaker + bullhorn will I be able to get the desired effect on a dog about 150-200 ft away?

It works good on some dogs at that range, but others can be within 50 and ignore it. We had 3 dogs next to us and 2 of them never noticed and the 3rd one would stop barking and run for the house. He would head to the house when he was at least 200 feet away, he soon became a non barking dog.

Q: Can this run on batteries? Or only DC power plug?

Batteries such as AA or AAA or similar chemical batteries are DC. The device does not come with a battery compartment. I guess if you attached a battery the device would work.
