[Elecraft] K1 and Ant on high amp car battery

Sun Jan 27 11:03:47 2002

Tom -- pardon me, but I really don't understand this question.  If you put 
an item designed for 12 volts into a 12 volt circuit, it will draw just 
what it wants (provided the source capacity is there) and no more. There is 
no need to put something in line with it.  I'm also confused exactly what 
the situation is "when you put the antenna switch to the battery."  But the 
result of what's happening seems to indicate that, when you throw the 
antenna switch, you are virtually shorting the battery circuit, through the 
fuse, to ground.  Please describe the circuit that you call the "antenna 
switch" in more detail.  Is this a t/r relay?  and, if so, what is the coil 
voltage of the relay? ac or dc? etc.?

thanks,
