I have an old Realistic (Radio Shack) "Stereo TV Receiver". It's like a
radio, designed to receive the audio from tv stations. I've used it as
an audio amplifier for one of my computers. But I just wanted to see if
it actually received TV audio. I dont have much for an antenna, just a
rabbit ears. So I am not getting anything, and where I live getting any
tv signal is rare.
 
However, I'm wondering if it's possible to get anything. This was made
for analog tv. It has 3 buttons to select VHF low, VHF high, and UHF. I
know all the digital stations now use UHF.
 
With the proper antenna, is it possible to get the digital signal on
UHF, or can that only be gotten using a DTV converter? This has me
puzzled....
 
* I noticed that at the very end of the VHF low, near Channel 6, I do
get a very weak signal of some sort. I suspect I'm picking up a little
FM radio, but it's too weak to really hear clearly.

They stopped analog TV broadcasting in 2009.

Your radio will NOT work with any of the digital stations,
which is 99.999 or so percent of them.
 
However, there are a number of exceptions, namely
some low power stations that operated on "channel 6"
before the cutover, and remained in operation.
 
They're actually exploiting a loophole and are really
using that channel, NOT for the tv image, but because
the audio portion of channel 6 is at 87.7 Mhz.
 
That frequency is right at the edge of the FM
broadcast band. The older, "dial" type, radios
generally have enough slippage, so to speak, to
be able to pick them up. However, many of the
digital display/control ones have a "hard cut"
and won't go that low.
 
Typical example:

I believe the Brits and their 'empire' still call'em condensers.

Condensers, yes. Piles no - that's French.
 
Never confuse the French with the English - that pisses them both off.

Then that just means all his other videos are suspect.

I haven't been on Usenet for over 15 months. The provider that I paid for is worthless, like much of what people post on these groups. I can read messages, but no longer post so I used Google Groups.

I think he hid the part number in the subject line. I search of

Holy Mozes, 21 pounds for a microswitch...............
 
Do they use gold contact springs maybe???

Pretty standard NO (Normally Open) SPST (Single Pole Single Throw)
microswitch. The only extra bit is the piece of plastic shown in the
photo. If the OP's plastic is fine then he only needs the switch. Hunt
around! Do get one that has regular electrical standards such as cUL for
safeties sake! Don't get a cheap one from China, unless you want a bit
more electrical fire/shock risk in your life.
 
Some switches do use gold contacts - if the switch is under 1A chances
are the contacts are gold flash (perhaps $0.01 worth of gold).

"Old pinballers never die, they just flip out."
adrian@poppyrecords.invalid.invalid (Adrian Tuddenham): Apr 12 08:19PM +0100

A few months ago I posted an enquiry about tickig noises that appeared
during periods of silence when making recordings with a Tascam DR-05.
These were only noticeable when the files were played back but couldn't
be heard in the monitoring 'phones during the recording session - which
was particularly worrying because it meant that I never knew when a
recording was going to be ruined until it was too late.
 
It now appears that I unfairly maligned the DR-05. I have just
discovered that if the files are played back on the DR-05, the ticking
noises do not occur. This means that 'ruined' recordings are perfectly
satisfactory as long as they are played out through the analogue
monitoring socket and re-digitised by the computer for editing.
 
The problem seems to be coming from the editing software (Peak L.E.)
which converts the Tascam's .wav files to .aiff before editing them. I
thought the differences between the two formats were just in the
headers, with the actual data bits being the same - but it appears that
something is being done to the data which trips up during periods of
silence.
 
Any ideas?

Is it possible the "ticking" is there even when you *do* have signal, you
just don't notice it (lost in the signal)?
 
Is the ticking at a very regular interval?
 
Note that a WAV file is made of multiple chunks, headers, data. Look up
the full details of the RIFF-WAVE format and see how much *could* be in
there. It is possible that Tascam are inserting periodical "other"
data into the stream - header, raw data, metadata, raw data, metadata ...
 
Some software does not fully implement the WAV file format properly,
and assumes 44 byte header, then raw data to end of file. It's lazy, and
it mostly works. Then sometimes it doesn't.
 
You could measure the time between ticks in e.g. Cooledit (Audition) or
others, by zooming in to the sample level. Or look at the file in a hex
editor. You may well find that the interval is a nice round number
of samples.
 
Of course, if Cooledit loads the WAV file correctly, you might never
see the ticks to zoom in on them :)
 
You could try submitting a minimal-sample of the file to Peak LE's
developers and see if they see a problem with their file handling?
