[Icom] Temporary radio installations

Sun, 18 Apr 2004 09:00:33 -0500

I have used the Radio Shack plug referred to in the first posting in my
Honda Civic Aux socket for over a year with no problem whatsoever.  I have a
2 meter FT-1500 transceiver.  Granted, I normally run at 25 watts, but I
have kicked it up to 50 watts when necessary, again with no problem.  The
Civic owners manual states that the socket is "rated at 120 watts (10
amps)."

I suspect the Aux socket in Mac's truck may be rated higher than my "little"
Civic.

Hi, Bill.

The "binding posts" are on the Radio Shack plug
that fits into the aux socket.

I was merely pointing out what appears to me
to be a superior plug to all I had previously seen.

I have measured the voltage at the binding
posts of the Radio Shack plug under load of
my IC-2400A at high power (~ 45W out).
There is a .6 volt drop between no load and
full load.  This holds true whether the engine
is off or running.  I attribute much, if not most
of that to the truck wiring.  I checked out the
situation last night and detected only a very
slight dimming of the panel lamps when the
rig was keyed.

The perfect setup?  No, but I have checked
out installations done by others where they
had wired directly to the battery and had
much greater voltage drop.

No need to apologize, Bill.  Apparently I didn't
make it clear that this was a temporary
installation.  Lots of folks need to make
such temporary installations such as in rental
or company vehicles, a lack of time, or a true
emergency.  Who is to say that they should
not be able to get on the air?

Not everybody has the luxury of having the best
at all times, despite the elitist attitude of some
people, who preach from some imagined place
on high.

p.s.  My Novice call of KN2GKK was issued on
30 November 1953.  Every license exam I took
was in front of FCC, including the Novice.

Mac, I have not paid any attention to pickup's or much else.  I know that my

Grand Prix has an "Aux" plug, identical to the cig lighter plug.  However,
you mention a binding post.  Is this upstream or downstream from the aux
plug you are using?  I read what you had posted.  Guess I did not understand

what you were saying...I apologize.

Any kind of point contact device scares the beejeebies out of me.  As I
said, been there...seen the results.  Don't know long you have been in
electronics, but if you remember the early diodes, such as the 1N82 series
and 1N22() series.  They may have been primarily for Microwave, but they
were the point contact devices.  One reason why they could not handle much
current..!  Diodes today are smaller and handle more...because the point
contact version died (for which a lot of us are thrilled)..!!

Good luck with the install.  Used a Mag Mount (VHF) for a while....and
replaced it by drilling a couple of holes in the trunk lid.  Range
immediately improved..!

Cold....last week we were shivering....this week 70's and low 80's....no
wonder people get sick..!
