If you notice a toner will </font><div><font size="3" style="font-size:12pt;">short and the tone will stop, or the light on the toner may glow dim. It's a dumb test but quick and dirty. It may be the tone will be muted still there but at a low volume.</font></div><div><font size="3" style="font-size:12pt;"><br></font></div><div><font size="3" style="font-size:12pt;">The other thing that could cause this is capacitance on the wire. The only way I have seen that removed is with something called a load pot, which is a coil to ground.</font></div><div><font size="3" style="font-size:12pt;"><br></font></div><div><font size="3" style="font-size:12pt;">It could be your wire is in water and needs to be direct burial type of wire or jelly filled. </font></div><div><font size="3" style="font-size:12pt;"><br></font></div><div><font size="3" style="font-size:12pt;">If you had a ground on the line you would hear a hum. If you have a bad ground at the power suppy or a bad filter in the power supply you will hear a hum. </font></div><div><font size="3" style="font-size:12pt;"><br></font></div><div><font size="3" style="font-size:12pt;">The way to test for capacitance is with an analog meter and when you hook it up or revers the leads you will see the meter kick.</font></div><div><font size="3" style="font-size:12pt;"><br></font></div><div><font size="3" style="font-size:12pt;">You could try replacing the ATA with a known good one and see if the ATA is doing it, itself. <br id="FontBreak"></font><br><br><font size="3">JeRy</font></div> </div></body>
