Cellphone<BR></FONT><BR></DIV>
<DIV></DIV>A few weeks ago I had a strange series of phone calls from a number
of acquaintances and family members. I was getting calls from people saying
Sara's (my wife, W1SLR) cell phone keeps calling me and when I answer all I
hear is a radio in the background; nobody talks to me. I spoke to Sara about
it and she had no idea what was going on. So we kept track of things and here
is what we pieced together.
<DIV><BR class=khtml-block-placeholder></DIV>
<DIV>(1) Vehicle is a 2005 Ford Focus Wagon</DIV>
<DIV><BR class=khtml-block-placeholder></DIV>
<DIV>(2) radio is a Kenwood TMD700A, wired directly to the battery through
appropriate fuses and a Rat Shack 20 amp rated line filter.</DIV>
<DIV><BR class=khtml-block-placeholder></DIV>
<DIV>(3) cell phone is a Samsung A650 with an "iGo" cigarette lighter plug
charging unit</DIV>
<DIV><BR class=khtml-block-placeholder></DIV>
<DIV>(4) the problem only occurs when the phone is on the charging cord.</DIV>
<DIV><BR class=khtml-block-placeholder></DIV>
<DIV>(5) every time the D700 pops off a position beacon (3 minutes) the
cellphone, if idle, first goes to the calls received list, and the next beacon
after that, dials the most recent entry in that list.</DIV>
<DIV><BR class=khtml-block-placeholder></DIV>
<DIV>[strains of the Outer Limits soundtrack rising in the background]</DIV>
<DIV><BR class=khtml-block-placeholder></DIV>
<DIV>(6) the same phone on the same charging cord in my truck, a 1992 Ford
Ranger, with an identically set up D700, has no such problem.</DIV>
<DIV><BR class=khtml-block-placeholder></DIV>
<DIV></DIV>
<DIV>Huh?????</DIV>
