Has anyone tried sending a "wake-up" command to an ERT meter?
In particular, I'm interested in reading an Itron 40GB ERT (gas meter) that is probably in "wake-up" mode instead of "bubble up" mode based on the fact I can "hear" other meters but not my own. Granted, I haven't done any exhaustive legal research but ISM frequencies are generally unlicensed if you stay within power limits, bandwidth rules, etc. (see your local WiFi access point) and I can't imagine an USB-powered RTL dongle putting out that much power.

There are a lot of reasons you wouldn't want to do this:
Rtl-sdr compatible radios are receive only, you would need a different radio.
Based on the information I've found about the wake-up signal used on meters like the 40G (I've got one), is that the wake-up signal is transmitted above the 902-928 MHz ISM band, and transmitting there would require licensing.
Most meters configured in wake-up mode rather than bubble-up mode have sealed batteries intended to last the lifetime of the device. Waking it any more often than the utility planned will kill your meter's battery faster than planned.
I don't believe the wake-up signal is meter-specific, so transmitting would wake any meters in the area that can hear it.
You might have to explain to your utility why all the meters surrounding your place of service died before their replacement schedule said they should.
You will likely be liable for the cost of replacing any meters that died prematurely.
