Sheesh, they should have joined AAA.

LOL.
I don't think it would take much of a map to find Los
Angeles or New York City or any other major U.S. city.
Conelrad was sort of locking the barn door not only after
the horse was stolen but after horses weren't used any more.
Until about fifteen years ago you could still see where
one of the large stages at Warner Brothers was marked
"Lockheed Aircraft", a left over from WW-2. WB is a few
miles from the old Lockheed plant and looks sort of like it.
Conelrad belonged to the thinking of the same era.

That to me does not make any sense. In an arms race, you pay (or invest)
in something that protects you NOW in the hope that it works while you
invest in something that will protect you in the future.

I'm not fond of the whole concept of an arms race, but sometimes we have
one forced upon us.

Geoffrey;

You should know that there is no such thing as a temporary governmental
project. And that's what these amounted to.

Now we have Google Maps that can be used for pin point targeting by pesky
salesmen, paparazzi and any other nefarious character. The threat is more
real now.

You have no idea. Hamas has been using them to target rockets.

It's just simple math once you have the co-ordinates and elevations.
Not counting wind drift and thrust variations. You all have my prayers.
Pray for us too. We are besieged by idiots who don't seem to connect
what they want to any sense of reality. History has no meaning for them.

I'm afraid that 640khz _is_ the correct lower frequency.
Somewhere, buried in some archive, the developmental documents for
Conelrad may still exist and may explain the choice of frequencies.
I think mostly it was to have a frequency that would be usable for
any BC station. I also don't remember (if I ever knew) the power
stations were supposed to use, I think quite low, perhaps a couple
of hundred watts.


You are right. That's what happens when you depend on memory. Sorry
for the error.

Dave


Memory? What's that?


I dunno. The other half says it's the second shortest thing I have. I
forget what the other thing is....

This should bring back some memories for those over '50' here.

Would anyone have a circuit, or know where to find one, for the Conelrad
device as marketed by Motorola and Heathkit.

Monumental failure? Easy conclusion, evidently. However there are
still WMD's pointed
at us, and we still have them pointed at others. Of course CONELRAD is not
an effective scheme any longer, but when WMD's traveled by airplane, and
came from
known geographical spots, CONELRAD was a pretty effective at denying
precision
target identification using simple navigation instruments.
I was always dismayed by having to have our radio or TV turned up so
loud that
it could be heard back in the hall closet that was my "shack". When Wife
was home, the
volume could be turned down, and she was to tell me if the station went
off the air.
(and it did, occasionally, sending a little chill, until determining that
it was not an alert,
but a "technical problem")

Old Chief Lynn, W7LTQ (then and now)


Last night, BBC 4 TV over here in the UK aired a compilation of Bob Dylan's
performances at the Newport Folk Festivals in the 60's. I was amused to
hear, in "Talkin' World War 3 Blues", the lines:-

"Well, I remember seein' some ad
So I turned on my Conelrad
But I didn't pay my Con Ed bill
So the radio didn't work so well!"

I often wondered what Conelrad was, thanks to this thread I finally know!

Roger Basford/G3VKM

The original question was whether someone had a circuit diagram of a
Conelrad device marketed by Motorola or Heath. I do not hink anyone
answered the question, although there were wonderful distractions.

Specifically, the Heath catalog of 1959 (and other years) contains
schematics of many of the Heath products, along with a description. I do
have that catalog so I could scan the schematic. Although copyright
protection has now been asserted as to Heath manuals, I do not believe it is
being exercised as to those schematics.

I still have my Morrow Conelrad receiver in my shack. It still functions as
intended and I often listen to the basketball or football game.

As to how an invasion works, I was down in Grenada the year following the US
invasion and spoke with many of the "invadees". It turned out that the US
did not have any good maps of Grenada, because they had not planned to
invade that country. They entered St. Georges and went to the local travel
agency and bought all of their maps of the island and used those to continue
their invasion. The "bad guys" had occupied a school on the top of a hill
right next to the ocean. The US gunships sat off shore and took potshots,
with their big guns, at the school. I remember examining a Russian
motorcycle that had been the victim of a direct hit. Not a lot of science
involved. The inhabitants of St. Georges were treated to a good show. The
local sandwich shop did well selling sandwiches to the US troops. The local
radio station still had lots of bullet holes in it and I recall the radio
station went off the air fairly quickly. Not sure if it was either 640 or
1240, though.

So, it seems that the best invasions, with the least loss of life, occurs
when the country invaded is basically peaceful, with no arms and no ability
to fight back. The entire process can be finished in a weekend. The
inhabitants get a good show, make a profit selling supplies to the invaders,
then get aid to rebuild after the invaders leave.
