measure audio w/ volt-ohm meter

[markdavis]

scwis,
what is a “normal” amount of audio voltage that
should be showing up at the end of the cable run?

Also, do you think if I were to put the test leads for
the the volt-ohm meter at the two parts of bare audio
wire where the adaptor attatches to the cable that runs
to the transmitter and then again at the end that it would
give me an idea of the % of power lost during the cable run?

finally, is there anything to prevent this attenuation or
to lessen it?

Thanks
