If you are getting 0 DC and 3AC, I am surprised. I would expect it to
be the other way around (0AC and 2-3DC). No matter, less it good and
your receiver is probably saying it can take anything up to 5 volts and
it can probably take much less, like maybe .1 volts. Some people on
this list have said their equipment works all the way to .025 volts. I
would double check your numbers and readings then try it.
