Let me add one more question to Frank or anyone that knows of these types of
radios.

I never took it mobile because on the inside of the battery compartment it says
:

Caution:" The battery charger will only recgarge the following nickel cadmium
rechargeable cells or its equivalent-EverReady CH4.0 Burgess CD 10 or Marathon
S103. All other batteries will over heat and cause leakage. Only use the above
prescribed batteries."


Apparently someone didn't pay attention because the inside when I got it had
some leakage, but I cleaned it spic-n-span.

My question would be, why can't I use just four regular D cells (that's what it
looks like it takes) and on the front of the radio at the bottom left corner it
has a switch that says 'Batt.Charge' and a red light that lights up when you
flip it because I've done it.

Why can't I keep the charger in the 'off' position and run the four Dcells??
Would it hurt anything?

Thanks to anyone who replies.

Well, I couldn't wait for an answer- so notice to anyone else- *Don't Bother.*

It means 'exactly' what it says on the inside of the battery lid. I popped 4
brand spanking new Dcells, kept the charger switch in the 'off' position and
nothing.:-(

I guess my only question left, and I can't answer this one Frank hint are
those batteries it said even made now? A couple of them I've never even heard
of, I'd really like to take that piece to the park, but where would I get those
kind of batteries that could be charged while playing (that's pretty cool FWIW
IMO.) :-( Waaaaaaaah

Wow, I have a Ross, have had it for two summers. I NEVER thought it was a
'World Master.'

I keep that one radio in a seperate room with a Radio Shack reel in

antenna
(the one with theadpter that pushes 'onto' your whip.....which I actually
prefer.

But I knew that picture didn't look nothing like mine so I got up and went

and
physically brought it in here and shined it up real good.

On my sig, I've always had Ross #2311 because that's all I

saw.....duh!!!!!!
Mine has the face plate in sparkling stainless steel or chrome. {?} It

says
on the lid *Solid State Multi-Band Sounds Around The World. In between

the
words Band and Sounds is a 'lip' that you lift the cover up.

It doesn't come off, on the inside of the lid on the left is the 'Time

Dial'
and underneath it says "outer Dial/Time of Day - -Inner Dial/Zone No. and

on
the right hand side of the inner lid it has a map of the world with the

numbers
starting on the far left of 1 through and ending at 24.

Help me out here Frank, I've never paid this dial much attention, what do

you
do? Like right now it is say 2am(local)....which is 0600UCT how does that

dial
coincide with that.......then what- you match it with the map of the world

and
know what their UCT is?


I know what you're talking about, but I didn't spend much time trying to
figure it out. I'm sure it should be pretty straightforward. The time zone
for UTC is in Greenwich, England, and knowing the time difference should
give a pretty good clue on where to set the dial. Then the pattern might
become clearer, and you can set the dial to remind you of the time
difference between any two places on the map.



That's something that I never paid it any attention, *BUT* underneath the

dial
and writings like I said, I'll be darn if it don't say 'World Master.' :-D

This thing is in MINT condition other than a small fact that it looks like

(was
like this before I got it) someone was painting and there's like tiny tiny
little specks-maybe seven of them of white paint.



Sometimes you can scrape the paint specks off with your fingernail or a
popsicle stick. I have some 3M plastic polish I bought at an auto parts
store which does a nice job of polishing and cleaning up that sort of stuff.
Toothpaste can also work for that. Some of the toothpastes are sorta
gritty, but Crest is one that's OK, if I recall. Be sure to try it on an
inconspicous area first.



It has seven 'push down' switches that I had cleaned with contact cleaner

and I
cleaned the 'tone' knob that has bass and treble and the volume

knob.....even
has a RED button that says Dial Light on it - and it works fine.


If yours has the piano key switches, like the one in the e-bay auction, be
careful with them. The plastic wasn't real strong when new, and can get
more brittle as it ages. That was the biggest repair I did on the World
Master last year. I glued some substantial pieces of plastic underneath the
stressed areases of the keys, and I think it should be holding up OK. I
gave the radio back to it's owner after I fixed it.



Each switch is in different BRIGHT colors and it has in order
LW(red)/AM(orange/MB(Green)/SW1.2(Blue/SW3.4(Brown)FM(Red/VHHF1.2(Green)

It has a 38"Telescoping Whip, that hwen pulled all the way out, it rotates
360%.

Thanks for bringing it up and getting me up to take a look at it more

closely,
I have a *Ross World Master* -gee-gotta change that sig now. ;-) FWIW, it
really is a good sounding and extremely selective SW radio, which I would

want
over sensitivity really.

Time to move her in the shack. Thanks!
But FRank or someone, I know it must be easy, but what's the deal with the

dial
and how does it work.....gotta be late.


As I remember the dial, I think it serves as a reminder of the time
difference between any two time zones.

Probably any Nicad D-cells with the correct flashlight type ends would work.
Rechargable batteries sometimes have different terminals when they are
intended for use in recharageable battery packs. Ni Mh batteries have
largely replaced Nicads, but there's still some Nicads around. Ni Mh and
Nicad have the same voltage, but Ni Mh cells can supply more current.
However, Ni Mh batteries are said to be degraded more quickly by trickle
charging than Nicad. Your radio almostly certainly trickle charges the
cells. Actually, trickle charging isn't real good for Nicads, either, but
almost everybody did it years ago.

If you want to try your radio on batteries, just flip the switch but don't
plug it in. The radio can't charge the batteries without external power.
Be sure to remove any non rechargeable batteries any time the radio is
plugged in.

Regular batteries have a bit more voltage than Nicads, but the difference
shouldn't cause any problems in a radio. The biggest difference is price.
Rechargeables are expensive, and alkalines will power the radio for a long
time. Just be sure to take the alkalines out anytime the radio is plugged
into an outlet.

Here's what happened to Burgess Battery:

And Marathon:

http://www.agcinfo.com/Projects/MARATHON.pdf

In short, it wasn't only the batteries which leaked.

I have checked the antenna and the connections are good and I've checked all
the wires going from the bandswitch to the circuit board, all seem ok. Before I
was getting AM, but now it has the same "low static noise" that the
Air/Weather/Police High band has. Does anyone have an idea what else I could
check?

As far as the adjustments someone here mentioned to align it. What band would
you test the alignment on. Of course if I do this, I plan on marking where it
goes in case the adjustment doesn't work. Any advice on which band to test it
on.

Thanks again for the help. :-D

You can check if the local oscillator is working on the AM band. The local
oscillator will probably run about 455 kHz above whatever frequency is
indicated on the dial. So, if the radio shows 1000 kHz on the dial, the
local oscillator is running at 1455kHz. This signal can be received on
another radio. Tune another radio to a station around 1450kHz, and tune the
radio you're checking to around 1000 kHz. You should hear a whistling tone
as the radio is tuned around. These frequencies don't have to be around
1450 and 1000 kHz. Anything with a difference of around 455 kHz works.
Many digital radios have different IF frequencies, and this trick may not be
workable for checking their local oscillators at these frequencies, although
they are fine for receiving the local oscillator at the higher frequency.


As far as the adjustments someone here mentioned to align it. What band

would
you test the alignment on. Of course if I do this, I plan on marking where

it
goes in case the adjustment doesn't work. Any advice on which band to test

Don't touch any of the alignment adjustments. If someone else has played
with them, the radio might be so out of whack it won't work normally
anymore. Alignment isn't a trouble shooting procedure, anyway. Generally,
a good alignment requires a signal generator and a service instructions.
Adjustments can be done with off the air signals, but that's not for
beginners. Leave the adjustments alone.



Thanks again for the help. :-D

I have an update. I managed to find out that the wire for the AM band (hidden)
had come loose from the board. Still couldn't find a loose connection in the
Air/Weather/Police High band. In the process though, there is now another
problem, maybe someone can help me with it.

I've located the power supply, and I see that there is a red wire and two black
wires coming out of it. The two black wires are soldered directly above the
power supply on the board. One of them, the one on the right came loose. What
is this wire and should I run the radio anymore, due to safety? Is it ok to run
it with this wire off for the time being, or will it cause a fire hazard?

Thanks for the help. :-D

I have read several messages about your WorldMaster multiband radio with
five bands. People have suggested testing components, and doing all sorts
of things to the radio, but I have not yet seen anybody asking the most
obvious questions we need to know in order to tell you why, or even if, the
"police" and weather bands are really dead.
What are the frequency ranges shown on the dial scales? For example, the
Am, or medium wave (MW), or "broadcast band, should show a range of
something like maybe, 520-1620 KHz or KC, or maybe 540-1600 or something
similar.

The FM broadcast band might run something like, 87.5-108.0 MHz.

Some of the radios from that period covered an aircraft band somewhere
between about 108.0 MHz and maybe 136.0 MHz. IN the 1960's and into the
1970's there may have been some police frequencies in that band, but I don't
think so.

It is very possible that the high police band and the weather band may have
covered frequencies from 136.0 MHz all the way to 174.0 MHz. If you're
lucky, that range would be covered in at least two bands, but I have seen
some units where one band allocation covered from 136.0 MHz to 174.0 MHz.
If the radio has no fine tuning control you will need a very steady hand on
the tuning knob to zero in on a narrow frequency slice that would be covered
by a station like a NOAA weather radio broadcast, or any of the police
frequencies that might still be in that band.

The VHF police band at the time that radio was probably new ran from about
153 MHz to 158 MHz. In some areas, especially rural areas well away from
the major metropolitan areas, there are still police departments and fire
departments using some of those frequencies.

Just about all radios I have ever seen with band designatins like you
mentioned are cheaply made and not very well designed. In addition to being
optimized from the wide bandwidth of the broadcast FM band as has been
mentioned, you'll notice that if you live in or near a large city, two,
three, or four of the strongest local FM stations will show up all over
those "police" and weather bands. YOu might even get the audio portion of
one or two of your local television stations on those bands as well, even
though they should not be heard there.

Some of those radios could surprise you, and would not embarrass themselves
at all on the AM broadcast band, 540-1600, or at night in the shortwave
frequencies between about 5.8 MHz and 10.0 MHz.

If you live within about 10 or 15 miles of an airport with a control tower,
you might hear something on the aircraft band that is actually supposed to
be there. Since 90 percent or more of the US population is supposed to be
within range of a NOAA weather radio transmitter, you should be able to hear
at least one of those stations, if a bit faintly, once you get the hang of
tuning so finely that the pointer moves along the dial scale in increments
about the space of the diameter of a hair.

If the radio was made in the 1960's, it was most likely made in Japan. If
it was made in the 1970's, it could have been made in Japan, or more likely
somewhere like Korea, Taiwan, or Hong Kong.

******rest of good reply snipped********

Brent,
I've received a few replies from Josey, he/she is a newbie- that's more than
likely why.

I'm glad the thread started so I inspected mine and found out what it really
was, hopefully I can find on here the answer to my question about the dial. :-)

You're right Brent. On mine it's in two. VHF1:108 through 140
VHF2:145 through174
and right underneath that and the bottom of the dial is the 'WB'(in Pink) It
goes in increments of : 0/10/20/30/40/50/60/70/162.5-followed by a little pink
dot. then 100. {?}

It picks up weather bands from two areas solidly and one time (real faint)
three. Could a loop help, nah.....not. That'd be something to be able to pull
in that third one in real clear like the other two.:-)
