WW2 Radio Compass
 

As you know I am mad about radios, WW2 airplanes, tanks & subs.

I was thinking about getting a compass so that I could better find my
possition at home. So I did a search on Ebay on Compass. I then came
accoss something that is called a Radio Compass.
EBAY Item number: 6565758752

My guess it that the gauge is telling the pilot his dirrection in the
sky. But why is it called a radio compass?

Is the device putting out a signal? And is the signal bouncing back?

It is a Radio Direction Finder.Some U.S.Military Aircraft (and some of
the Allies Aircraft used them too) used them with a loop antenna mounted
on the Aircraft.

No, it's a radio receiver with a directional antenna. The display shows the
compass bearing to the radio station being received. There used to be
portable radios, usually the "all band" variety, that had built-in radio
direction finders (RDF's). Heathkit even had one, though I don't recall the
model number.

My old buddy owns an ex U.S.Navy Ship Compass.He was in the U.S.Navy
active duty for four years on the U.S.S.Ticonderoga back in the early
1960's (they were shootin at Whales,Tonkin Gulf incident,at the same
time,I was humping ammo in Vietnam) and in the U.S.Navy Reserve unit
here in Jackson.One day they were getting rid of some old things at the
Reserve unit he retired from here in Jackson on Jefferson Street and
they gave him the Compass and an Anvil (I have been trying to talk him
out of that old Anvil for many years) and a few other things.One of the
balls was missing from the Compass (it is a big heavy Compass,stands
over waist high, and about twenty years later I was in Pensacola,Florida
and I saw a big store that sells antique nautitcal things and they had a
Compass ball in there for sale for $40.00.I phoned my old buddy long
distance and I asked him what diameter the Compass ball on his Compass
is.I bought that Compass ball at the store in Pensacola for him.

No, LORAN uses time measurement.

A Radio Direction Finder basically points in the direction of a LW or MW
radio station.
Have you ever used an old AM radio with a ferrite rod antenna inside? If you
turn the radio around the signal drops out if the end of the radio is
pointed toward the AM broadcast antenna.

Old direction finders used big circular crossed loops, now ones use a block
of ferrite with two windings on them at 90°.
With a combination of signals driving servo amplifiers, it is possible to
drive a device called a Goniometer to a null position, ie no signal, then
read off the bearing.
With a bit of practice, you can do the same thing with an old transistor
radio. BUT - they aren't very accurate. 4 or 5 degrees was considered
excellent. If you are trying to get a bearing on a distant station, be sure
you are using the groun wave, as the ky wave can distort and come in from
different angles.

Most modern aircraft carry an ADF receiver, but some are being removed in
favour of GPS.

There is an old Humphrey Bogart movie (I don't remember the title of the
movie just now although I have seen it a bunch of times before) and
Humphrey plays the part of a bad guy in the movie and they are going to
steal the payroll from a gas plant.One of the crooks buys a tractor
tanker (sort of like an 18 wheeler) and a guy who is playing the part of
one of the crooks,but is really a copper,installs a radio tracking
device underneath the tanker so the coppers can trace the truck
tanker.It is a real good old Humphrey Bogart movie.

Ok I have a Panasonic 2200 shortwave radio that has the ferrite rod
antenna on the top. Often I have to tell people that it is not a handle
dam it!

I once used it while driving from Florida to New York. As I got closer
heading north, I tune it to a strong NY station, and yes the signal got
stronger.

Now I understand what an trans-oceanic radio is. I am still looking for
information of the radio that C. Linberg used.

As a kid I use to take broken am transitor radios apart. Many of them
had a small ferrite rod inside. But I noticed that pocket radio (later
on known as walkman)did not have them.

Some ferrite rod look like a minature dipoles. Different tiny thead
wires coiled around. As a matter of fact I recently built a 90 feet per
side dipole coiled around pvc tubing, which is hollow. And I thought to
myself, what if I where to put a long iron pipe inside the top part of
the pvc tubing? -(looks like a T)

Also, thoughout the 1970's when big stereos became popular, (you know
the record player, 2 wooden speakers, radio with a long am/fm bandwith
with a cool red lighed niddle, silver face plate, solid state, 8track
and the girlfriend) many of them had an odd long plasic thing in the
back. It looked like something you would put your toothbrush in. LOL!

I would often say to myself: if that is an antenna, what a strange place
to put it!

As for LORAN, I think I hear the last of the LORAN signals while I was
in Florida. It was around 150 KHZ.

Yes. BUT. The DF principles I have described do not work effectively above
MW. Ferrite antennas are less effective. The thin wire you described it
called Litz wire. Also remember that point I made about skywave signals
coming in from different directions to groundwave. Very nasty errors occur
at dusk and dawn due to diurnal shift.

The alternative is to have a log periodic or perhaps a StepIR tunable,
turnable array.

I am reading his question for the point of view of DF'ing ANY radio signal
in an effort to gain knowledge of it's possible source.

VOR is a deliberately phase modulated signal, as is TACAN. Not much point
DF'ing them from a ground station since their location is known, or can be
found from the Ident. Now UHF DF certainly has some applications,
particularly if DX'ing FM broadcast stations, but so would a yagi and a
rotator.

Since the newsgroup is r.r.shortwave, then DF'ing shortwave seems to me to
be the topic. Here is another method worth trying, particularly because of
it's compact size. http://www.qsl.net/dj3tz/loop1.html

And a significant point is that a "radio compass" was so simple, because
it was at a time when applications for radio was relatively small. The
more complicated systems came later, when things had built up and a
need for something better came along.

Direction finding has come to mean tracking down an unknown station, but
in the case of a Radio Compass the scheme is identical, using a directional
antenna and a basic receiver, but you pick a station you know the location
of, so when you point to it you know you are going the right direction
(unless you pick the wrong side of the null, and go 180 degrees in
the wrong direction, but there were ways of fixing that).

While there were beacon stations set up for Radio COmpass use, I gather
it was not uncommon to use existing broadcast stations for the purpose.

Were talking sixty to seventy years ago when they first started using
Radio Compasses.

That's right. A Radio compass is like DF'ing in reverse. I know where you
are, so where am I?
ADF is still an approved and popular form of aircraft navigation. The VLF
beacons are maintained for that purpose.

Whilst broadcast stations were also used for navigation, it was not really a
recomended practice. The radiation pattern could change, but more
importantly, without a proper identification, it was possible to DF on the
wrong transmitter, sharing the same frequency. If they carried the same
music program, there may be no way to know until the pilot is truly lost.
That said, the ABC station near us is called 2RN and is the inbound
checkpoint. That's mostly because it is a big thing with flashing lights.

Where is SR located? If he tells us his home town or local airport, we'll
find a beacon for him to practice on.

nothing else is on the band.

Within my 10-20 or so radius area their are two big air port and not far
from the Atlantic. I noice that on the upper part of the medium band I
sometimes pick up a CW beacon. I belive it's a beacon because it
repeats it's self in perfect timming. I had not yet decoded the message
yet.

Now, MFJ sell an interesting device, it's looks like a black flat box

The Lady on 10MHz is in Hawaii (WWVH), the Man is Ft Collins (WWV). I think
the calls are correct. Mostly I hear WWVH and JJY (Japan). Listen around the
1/4 hour marks for an ident. I can hear both WWV's tonight. 30m is open to
the USA. Unfortunately it is also being jammed by a bunch of Asian pirates
yakking on the same frequency.

The morse code ident on the aircraft beacons is slow enough for you to
decipher it one character at a time. You can then go to airnav.com and enter
the callsign into their search engine and it should come up with some place
local to you.

Take Flushing for an example, they even spell out the Morse for you:

NDB name Hdg/Dist Freq Var ID
BRIDGE 022/12.9 414 12W OGY --- --. -.--
PATERSON 137/17.6 347 12W PNJ .--. -. .---
BABYLON 301/21.4 275 14W BBN -... -... -.
CHATHAM 096/27.2 254 11W CAT -.-. .- -



On a nice quiet winters night I was testing an aircraft ADF and trying to
point to a station about 100km south. The needle was flicking back and forth
between south and north. When I decoded the mixture of callsigns, instead of
SLS (shelleys) I came up with LRE (Longreach.)

Longreach is in northern Queensland and about 1800km away. Now that's not
bad DX with a ferrite antenna at 12" off the ground!

I'm not familiar with the MFJ device. Is it a CW Code Reader of some sort?

By the way, the beacon at the top of the MW band is more likely to be a
Marine beacon. I have no experience with them, but Google is your friend.
There are some Marine beacons at VLF, but most are aircraft.

Let's see, it must be 12 years since I was last in Queens. Wow, time sure
flies.

Ok, I didn't make myself very clear there. In my area, the radio stations
have agreements to share their towers, and to carry multiple transmitters.
After a lightning strike, one local station lost everything, but 6 hours
later, they were back on the air from a neighbours tower. Not very handy if
you happen to be DF'ing the wrong location! NOTAMS are not required for
Commercial Broadcasters, so it could be a disaster for the uninformed.
