From the documentation I've found, it is possible achieve resonance at a lower frequencies. 30Ghz is just one of many harmonics. There are many factors which determine the resonant frequency:
1) Impurities. Natural impurities in the water, (unless your using distilled).
Which wasn't used, at least in Stanley Meyer's device because there is no electrolyte in it at all.
2) Electrodes. Will also add some impurities and if it is a consumable electrode such as in most lab and commericial electrolysis devices (carbon rod), their mass will decrease over time and will introduce more impurities as they decay. Stanley Meyer used non-consumable rods (316 stainless) Stainless steel hadn't been created when Faraday published his 1st and 2nd laws of electrolysis in 1834.
3) Water level. As the water is used up its mass will also decrease, of course you could add a precision pump to maintain levels but would require more energy.
4) Water Temperture. As the temperature rises the viscosity will change, affecting amperage draw. A cooler could be used but would also require more energy.
At 10C (50 Fahrenheit) Viscosity of water = 1.308 × 10-3 Pa*s
At 30C (86 Fahrenheit) Viscosity of water = 7.978 × 10-4 Pa*s
All these factors will determine the resonant frequency. Since they are constantly changing so will the required frequency to maintain resonance. Therefore there is only an ideal theoretical resonant frequency of water. To seperate water into Hydrogen and Oxygen using resonance efficiently a device would need to operate on a PLL (Phase Locked Loop) to adjust the frequency according to conditions within the cell in order to maintain resonance and achieve maximum gas output.
"We can see oscillations in a bowl of water and estimate that they have a frequency of a few Hertz. Small water drops, about 1 millimeter in diameter, have a resonant frequency about 100 Hz, and approach 1000 Hz at about one half millimeter diameter"

"The natural frequency of water is a bit more complicated, because it takes into account the mass of water molecules, the attraction between molecules, the distance between molecules, and some other stuff. Suffice it to say that most microwave ovens put out a frequency of 2.5 gigahertz. This means that these microwaves pulse 2,500,000,000 times per second. This isn't the lowest (also known as "primary") resonant frequency for water, but microwave manufacturers use 2.5 GHz because they want the microwave to work at any and all water temperatures. There's lots more techno-babble about resonance, matching, and the engineering of microwaves, but that'll have to be a separate question."

Also it is possible to seperate water it into hydrogen and oxygen by subjecting it to micowaves. John Kanzius a retired TV station owner, broadcast engineer and cancer survivor was looking for a cure for cancer and found he could do just that. The process is less energy efficient then standard electrolysis but it can break water it into hydrogen and oxygen.
