Hi David

I wasn't really asking about acoustic energy, I was asking about RF
energy, frequency, radio frequency. Not sure where you came up with your
assumption.

I got it from you:

So if your voice is about 10000 to 20,000 hz to
which then dogs pick up just higher,

Voice = acoustic.


Of course I asked the question, which means I didn't know.

I hope you are not a teacher, I would be an angry taxpayer in your
community.


Perhaps you should go back to whoever taught you about RF and get your
money back then.

Radio Frequency, a electro magnetic field from 3khz to 300ghz.

This RF is a specific freq? RF could just be a general statement,
meaning anything RF. So if your voice is about 10000 to 20,000 hz to
which then dogs pick up just higher,

RF ?? What a broad statement.

How were you able to obtain an amateur radio license without knowing
the difference between acoustic energy and electromagnetic energy?


So what about the batteries? Anyone got success or bad luck with a
online dealer? I see them on ebay for about 40 bucks, shipped, seems
about fair for a 12v.

Anyone who thinks he's picking up radiation from rocks on his HT
probably shouldn't be messing around with batteries, it might be a bit
over your head.
