[Icom] Temporary radio installations

I doubt that Riley would take into consideration that someone
did not have time for a proper installation, when a lousy
signal goes out on the air.

If it is not worth doing right, then forget it and run a 5
watt rig...

Check my message again, Bill.  I point out that
this is  NOT  the cigar lighter socket.  It is a
dedicated power outlet being provided in
many pickup trucks these days.  Yes, it is
a "point" contact, but it is about 1/4" in
diameter and the Radio Shack plug that I
mentioned is more robust than any other
similar plug I have ever seen.

I'll measure the under load voltage at the
plug tomorrow.  Very easy to do since the
connection at the plug (as I said) is binding
post and banana jack.

Again, I  SAID  this was  TEMPORARY.  I ran
out of time to make a full install before I
leave on a trip.  Magnet mount 2m/70cm
antenna on the roof will have to do until
I get time to drill a hole in the roof and do
it properly.  With no place to get the truck
indoors, I have not been too inclined to
do the work out in the cold.

Mac, the other problem that many seem to ignore is the plug
itself.  It is a
point contact with the mating receptacle.  Think this way.
How long would
you hold (or be able to) hold a plug against the cig lighter
without burning
your fingers from the heat.  Most lighters, unless brand new
vehicle
install, have been used.  For whatever reason.  This deposits
"crud" on the
cig lighter side (and on the lighter).  This "crud" is the
equivalent of a
series resistor (just like the spring in some adapters).
These do have a
finite IR drop, which generates heat.

Unless you are running less than 25 or 30 watts, I say, #$%
the cig lighter
plug and go direct to the battery.  Less problems this way.

I have seen too darn many guys who run 50-100W and wonder why
their
modulation sounds like hell.  Put it plain and simple.  The
radio is seeing,
maybe at most 10-11V under load.  Most of the current radios
in use all but
"demand" 13.8V at the radio.....period.

I have yet to understand why guys use these stupid little
things and then
complain...some guy said the audio sounded horrible...!!

There are ways to the battery.  If you don't want to take the
time to find a
good solid source of power for the radio, then do not complain
because
someone faults your signal..!
