No I didn't. That's a real FUBAR damn! I've actually been inside WWVA
studio for the Saturday Jamboree back in the late 50's early 60's. My dad
announced a commercial for one of the sponsors and had a friend who was a
musician that performed in the studio.

That is the second set of towers that have collapsed at WWVA.

I was in the WPFB studios and engineering area a number of times.
They lost a tower to high winds or a tornado in the late '60s or early
'70s. I can't find any reference online.

I also found that their long time country DJ, Moon Mullins passed
away. He was a friend of my dad, when they were growing up.

From: "N_Cook"

Am I on a hiding to nothing? trying to crack a device with unavailable
remote control, and no button functions to speak of. Is there a technique of
sniffing a microcontroller to at least find the basic pulse repition rate?
perhaps inductive loop over the package or monitoring to nA level in supply
current would register a blip, or is it all or nothing?
Anyway
First tried this with Mitsubishi BD 512 "universal" rc
Removed the 4MHz resonator and fed in a sig gen of about 1.5V pk-pk
(previously scoped), floating from the rc battery levels. With a known
receiver and transmitter code selected, then functions would work over range
3.3 to 5.8M then fail outside that. The rc would work with 1.5V sine between
300K and 10.5M. Didn't continue with that one as you had to manually step
through each in-built code.

Got a few no-name URCs from UK Poundland "pound shop" , badged as Signalex ,
81415, 10 in 1 . 1 GBP for all the functionality of a URC. This type you can
set it to flicker away to itself until it reaches the end of a batch of
codes.
Removed the 3.58MHz resonator (why so apparently accurate?) . With 1.5V
pk-pk locked in with receiver over range 2.7 to 5.1M, and again about 300K
to 11M would operate using 1.5V. So far have only used with original 3.58M ,
6M and 7.5M sine inputs. Am I serendipitously likely to get a hit
somewhere, at least the unit on/off model recognition code if not function
code plus the model code

So 2 out of 2 of these URC have been amenable to this mod but no match to
the unit in question found so far. Is there any general guidelines for
makers to choose certain types/ranges of coding for different types of
equipment or is it totally open for them to choose? Assorted bits of kit
show at least partial responses to some of these off-spec codes, but not my
target one so far.

That's the NTSC color carrier frequency. Not only were they made in the
billions over the years (every US/Canada/Japan, etc) color TV had one,
so did every VCR, and lots of other things.

I'm sure they will still be around for a while because while digital TV
has taken over in the US, it has not in the entire world and anything with
a composite video input or output needs one.

They became the defacto standard for things like telephone dialers,
and many things that needed about a 4mHz crystal because they were so cheap
and plentyful.

One of the famous "blue boxes" (telephone hacking devices) was made by
taking a Radio Shack tone dialer and replacing the 1mHz crystal with a
3.58mHz one.

Look up LIRC (Linux Ifrared Remote Control). There is a library of remote
codes, a way of capturing new ones from a remote and since the definitions
are in a text file, they are easy to "hack".

There are all sorts of input and output devices, if you have a PC with a
regular serial port (not USB), you can build a transmitter from the proper
plug, a resistor and an IR LED.

I was not aware of that frequency as being significant , the equivalent over
here is millions of 4.433619MHz and x2 of that , quartz crystals for Phase
Alternate Line. That would explain why it was Never The Same Color (twice)
if they could get away with using ceramic resonators rather than quartz.

I'd already looked at LIRC but no listing for my device. Yes easy enough to
knock up an IR transmitter tacked onto a PC but I've not found a library of
codes or algorithm for generating all permutations of IR transmitter codes,
model trigger code or model plus functions

Often the ceramic resonators were used as filters and for devices that were
designed to work at those frequencies, but where it was not critical.

I no longer have an LIRC setup to do it with, as I replaced my MythTV box with
a WD TV Live. If you can find someone with a little PERL programing experience,
they could write a program to copy each remote over to the LIRC config file,
restart the LIRC daemon and send some codes.

Then it would wait for you to hit a key, and try the next one.

It does not have to be very accurate, for example, if your program were to send
off, vol up, vol down, channel up, channel down, start and stop and something
happens at all, you have the correct frequency, spacing etc. From there,
you could play around to get the codes.

If I remember correctly LIRC was ported to the Palm Pilot, and if you could
get it to work on a Palm III or similar device, there are lots of them in
drawers just waiting for someone to ask for them.

Toasters even had a 3.58 xtal in them. Phreakers were removing them and
replacing the xtal in walkie talkies so they could mess with drive up

In the UK we were deprived of Cap'n Crunch 2600 Hz whistles and the phone

I remember visiting the UK in 1984 and trying to call back to the US. The only
way to do it was to call the long distance operator and place a request for
your call. When your turn came up, they would call you back.

Trying to call from a pay phone at a rest stop on a motorway was a comedy
routine straight out of Monty Python. The operator needed the area code
and number of the phone I was calling from to place the call.

In those days, there were no area codes on the phones themselves nor was there
any marking on the phone as to where I was or the exchange it was on.
All I knew was that I was at a rest stop a tour bus had made somewhere
between London and Bath.

Another time, I wantedto leave a message on an answering machine, as in
"look up the EUROPEAN size you want and I'll call you from Paris when I
can buy it". After ten minutes of standing at a pay phone in a B&B, the
oeprator finaly got through and as soon as he heard the recording, he
hung up.

I could whistle at 2600hz and hang up the central opertator line. I made a
blue box for a friend but he got busted before he used it. He was a greek
with dual citizenship and had a girlfriend in Greece he would call using
a reel to reel tape with some prerecorded tones on it. He got the idea
from one of his greek buddies that was here visiting that built a working
blue box and recorded the tones and their sequences on tape. The box was
easy to build, all tin can 741 op amps on a self etched PC board. Problem
was tuning it, I was only 17 back then and had no way to tune it. Said
friend was set to take it to school electronics class and tune it when
the FBI hauled him off one early morning in his boxer shorts :) He was
deported back to Greece and lost his US citizenship.

Sigh. The ceramic resonators were used as a chroma trap. Quartz
crystals were used for the color reference. As far as 'Never The Same
Color', network programing was carried across the US on buried coaxial
cables or by microwave relays. Unlike tiny European countries, we
couldn't broadcast from a singe site. Because of this, they were video
amplifiers and equalizers spaced at regular intervals. Because it was
mostly tube, and there were thousands of them in each network they
required constant maintenance. When the network switched to a different
feed from a different studio, there was a phase difference. temperature
changes on the coax caused it's properties to change, as well. That was
why VIR and VITS were developed. It allowed for automatic equalization
to compensate for temperature changes, or when a signal had to be
rerouted. There were a lot of redundant paths, to allow for equipment
failures, or live remote feeds in the days before STL equipment. The
flexibility of the system was proven when Bell Telephone technicians
tied every TV station in the country together in a couple hours, to
allow full, live coverage of the assignation of President Kennedy. I
was at school when it was announced over the PA system. Less than an
hour later, all the students were in the auditorium watching the news
coverage live. By using some spare equipment and knowing the system
inside out, they were able to adapt it to a use it wasn't designed for,
with no permanent changes.

Also, when the nation wide distribution system was designed and
built, there was no color TV. The fact that it could handle color at
all proved that it was well designed.

Sneer all you want about NTSC, but the 'National Television System
Committee' was around a long time before color TV.

This is basically backwards. The US had high quality, phase-linear
transmission systems. Europe did not. The problem with NTSC was sloppy
studio standards.

They found out in part by talking to his girlfriend. She explained that
he used a tape device. I stayed at his place the night before so i was
there at 6 am Sunday morning when they came a knockin on his door. I was
zipped up in a sleeping bag peering through an opening when he answered
the door (had a safety chain) opening it part way just enough for an arm
holding a gold badge to pop through :) I stayed in the bag while they
looked for a tape device which he didn't have there at the time. They
found a loop of tape on an Echoplex tape delay box for guitar that he had
and un-looped it with a pencil thinking they found the evidence :) They
asked him who was inside the sleeping bag and he said just a friend and
they never bothered me. He had hid the blue box pretty well and it wasn't
found because they found the tape quickly so they were satisfied they had
what they were looking for. When they left I dug out the blue box and
destroyed it. Since they really had no evidence of a device that could
make the calls but knowing the calls came from his number back when he
was living with his parents they could only deport him and revoke his
citizenship. He never went on trial for the calls. Just was given a plane
ticket and said see ya later. They probably made it impossible to get a
visa back into the country since I never saw him again. But he did call me
maybe 10 years later from Greece. He said he was in a friends recording
studio. That was in 1982.

Lots of TV programming was not in color here until 1967. I remember an
old Soap called Dark Shadows. I remember when they first started airing
in color. Must have had problems because they when between B&W and color
almost every other daily episode for weeks.
