Fellow time-nuts:
I've got a circa 1964 DY-5842 VLF receiver. This is (was) operated in
conjunction with an external time interval counter to make a frequency
comparison. So you would select WWVL for example, and use that as your
primary standard for comparison to your local standard. It's got 5 crystals
in it: 16, 18, 19.8, 20, and 60 kHz (listed as GBR, NBA, NPM, WWVL, WWVB).
It works and I have the manual. The thing is, the interest in something
like this is bound to be a bit narrow, so I thought I'd mention it here.
So if there are any collectors, equipment museums, etc. that might be
interested in this, please let me know. I'm a bit sentimental about this
thing, it's sort of a bit of history, and from what I can tell, somewhat
rare (doesnt make it worth anything though :). Since it's a bit of a
curiosity, I'd like to pass it to someone that might be interested in it
rather than just tossing it. I can always provide more details to anyone
that wants them.
Best regards,
Paul Davis - K9MR

I've received a few expressions of interest. So I've put up a few
pictures at http://www.pumpkinbrook.com/DY-5842/ , just the front,
back, and top views. When I received this, there was no top or back
panel, I didn't remove them for the pictures. In those pictures,
you'll see that there's some accumulated crud, just dust really, that
could be cleaned off. But there it is in all its glory, warts and
all. In fact, it's old enough the orange paint has been peeling off
the meter needle :)
It's 19" rack mount, the manual says 10-5/32" high and 16" deep. It
also says 35 lbs, but it really doesn't seem that heavy to me.
Someone suggested that I pdf the manual, and I can certainly do that,
but it will be next week. I'll post it when I get it done.
Thanks for the interest.
Oh, and I'm in Massachusetts btw.

Very nice indeed
Will need some tlc, but thats the way it is for a 40 plus year old device.
What I saw in the back picture was even more interesting I have that bliley
crystal.
I picked it up at a hamfest 20 years ago. Now I know what it most likely
went to.
I am in franklin mass and if it doesn't go to a good home count me in.

In case anyone was wondering, the receiver has found a home with Paul,
WB8TSL. He tells me he's got it receiving WWVB already. It will need a
little TLC, but it was good to see its basic functionality confirmed.
I've posted the scanned copy of the manual on my website at <http://www.pumpkinbrook.com/DY-5842/
for those that are interested.
Thanks for the interest, and the replies.

An update. Indeed its working very well now. Easily at -88dbm. Its quite
interesting in the fact that if you set the Local oscillator exactly at 160
KC which today is easy to do, you actually have mis-adjusted it. It dawned
on me this morning that since its a freq LO add and then subtract scheme.
That you actually adjust it for peak signal through the 100KC IF.
Essentially disregarding slight literal offsets. (This is the same approach
some navy receivers use back in the 70s, and some older ham equipment.)
The unit cleaned up very well though still have some tape glue to remove and
label gunk from stickers.
The biggest challenge is gently pulling the meter out and removing the
peeling needle paint thats jamming the needle. No coffee during that
exercise.
Regards
Paul.

I have had some success with putting the meter scale back down with
water. It seems on some meters
that the scale was a decal that had a water based glue. I used a tooth
pick to put a drop of water under
the part that was lifted and the used the tooth pick to smooth the scale
back in place.

Thanks Bill the scale is fine. Its the meter needle that had paint peeling
off.
Just pulled the meter and removed the loose paint. Also just scanned the
meter face so in the crazy possibility of the decals peeling I can just
print a new face.
Now to locate a hobby store (that may actually be really tough these days.)
and find some enamel paint of approx correct color.
Kind of a florescent red and really a little dab will do you.

The ability to easily do this kind of graphics stuff (scanning and
printing) at an affordable price is one of the few recent innovations
that I appreciate over the great design and longevity in older tech
equipment. Meld the two = win-win.

The unit cleaned up very well though still have some tape glue to remove

The biggest challenge is gently pulling the meter out and removing the
peeling needle paint thats jamming the needle. No coffee during that

I have had some success with putting the meter scale back down with water.
It seems on some meters
that the scale was a decal that had a water based glue. I used a tooth pick
to put a drop of water under
the part that was lifted and the used the tooth pick to smooth the scale
back in place.

In case anyone was wondering, the receiver has found a home with Paul,
WB8TSL. He tells me he's got it receiving WWVB already. It will need a
little TLC, but it was good to see its basic functionality confirmed.
I've posted the scanned copy of the manual on my website at<

Thanks for the interest, and the replies.

Fellow time-nuts:
I've got a circa 1964 DY-5842 VLF receiver. This is (was) operated in
conjunction with an external time interval counter to make a frequency
comparison. So you would select WWVL for example, and use that as your
primary standard for comparison to your local standard. It's got 5
crystals
in it: 16, 18, 19.8, 20, and 60 kHz (listed as GBR, NBA, NPM, WWVL,
WWVB).
It works and I have the manual. The thing is, the interest in
something
like this is bound to be a bit narrow, so I thought I'd mention it
here.
So if there are any collectors, equipment museums, etc. that might be
interested in this, please let me know. I'm a bit sentimental about
this
thing, it's sort of a bit of history, and from what I can tell,
somewhat
rare (doesnt make it worth anything though :). Since it's a bit of a
curiosity, I'd like to pass it to someone that might be interested in
it
rather than just tossing it. I can always provide more details to
anyone
that wants them.

The ability to easily do this kind of graphics stuff (scanning and
printing) at an affordable price is one of the few recent innovations
that I appreciate over the great design and longevity in older tech
equipment. Meld the two = win-win.

I have an HP-4508A Vector Voltmeter that has a bad case of meter paint peeling. I took pictures to have in case it gets worse (which it probably will), but I am concerned that any attempt at taking the meters apart (as I would need to actually scan the meter faces directly on the scanner to have a scale image without to much distortion) would result in most of what's left of the paint to fall off.
This probably should go on the HP_Agilent news group, but I was wondering if someone in this group had experience with rebuilding those or similar meters.

Thanks Bill the scale is fine. Its the meter needle that had paint peeling
off.
Just pulled the meter and removed the loose paint. Also just scanned the
meter face so in the crazy possibility of the decals peeling I can just
print a new face.
Now to locate a hobby store (that may actually be really tough these days.)
and find some enamel paint of approx correct color.
Kind of a florescent red and really a little dab will do you.

Didier,
Its subjective then. If its bad enough you take the risk because you do know
the process will degrade the scale. Essentially when its time to do it you
will.
So the good news is this. With todays tools you can very accurately
reproduce the meter scale. I scan them at 1200 dpi as I just did for the
dymec. I prefer bitmap over jpeg for storing them.
Additionally with the various paint programs that seem to come on every pc
today you can always fix issues pretty easily. Then print to your favorite
material which most likely is a white picture material. (I like it because
its a bit thicker and more stable) Though good quality paper
is excellent also.
Hmmm maybe we should send our meter scans to K4BB repository. Heck he has
rom images.
Regards Paul.

If Diddier is reading this, wonder if we could add a meter scale to your
fine manual repository?

I have had some success with putting the meter scale back down with
water.
It seems on some meters
that the scale was a decal that had a water based glue. I used a tooth
pick
to put a drop of water under
the part that was lifted and the used the tooth pick to smooth the scale
back in place.

I've got a circa 1964 DY-5842 VLF receiver. This is (was) operated

conjunction with an external time interval counter to make a
frequency
comparison. So you would select WWVL for example, and use that as

It works and I have the manual. The thing is, the interest in

It seems to me,
There was a program or two that someone (or more) had written to do meter scaling. It was designed to print properly on an hp laserjet as I recall.
At the moment am unable to find it in my list of links or programs on my computer. But Google should give some answers.

This probably should go on the HP_Agilent news group, but I was wondering if someone in this group had experience with rebuilding those or similar meters.

It seems to me,
There was a program or two that someone (or more) had written to do meter
scaling. It was designed to print properly on an hp laserjet as I recall.
At the moment am unable to find it in my list of links or programs on my
computer. But Google should give some answers.

I have had some success with putting the meter scale back down with
water.
It seems on some meters
that the scale was a decal that had a water based glue. I used a tooth
pick
to put a drop of water under
the part that was lifted and the used the tooth pick to smooth the scale
back in place.

I've got a circa 1964 DY-5842 VLF receiver. This is (was) operated
in
conjunction with an external time interval counter to make a
frequency
comparison. So you would select WWVL for example, and use that as
your
primary standard for comparison to your local standard. It's got 5
crystals
in it: 16, 18, 19.8, 20, and 60 kHz (listed as GBR, NBA, NPM, WWVL,
WWVB).
It works and I have the manual. The thing is, the interest in
something
like this is bound to be a bit narrow, so I thought I'd mention it
here.
So if there are any collectors, equipment museums, etc. that might
be
interested in this, please let me know. I'm a bit sentimental about
this
thing, it's sort of a bit of history, and from what I can tell,
somewhat
rare (doesnt make it worth anything though :). Since it's a bit of a
curiosity, I'd like to pass it to someone that might be interested
in
it
rather than just tossing it. I can always provide more details to
anyone
that wants them.

I have had some success with putting the meter scale back down with
water.
It seems on some meters
that the scale was a decal that had a water based glue. I used a tooth
pick
to put a drop of water under
the part that was lifted and the used the tooth pick to smooth the scale
back in place.

I've got a circa 1964 DY-5842 VLF receiver. This is (was) operated
in
conjunction with an external time interval counter to make a
frequency
comparison. So you would select WWVL for example, and use that as
your
primary standard for comparison to your local standard. It's got 5
crystals
in it: 16, 18, 19.8, 20, and 60 kHz (listed as GBR, NBA, NPM, WWVL,
WWVB).
It works and I have the manual. The thing is, the interest in
something
like this is bound to be a bit narrow, so I thought I'd mention it
here.
So if there are any collectors, equipment museums, etc. that might
be
interested in this, please let me know. I'm a bit sentimental about
this
thing, it's sort of a bit of history, and from what I can tell,
somewhat
rare (doesnt make it worth anything though :). Since it's a bit of a
curiosity, I'd like to pass it to someone that might be interested
in
it
rather than just tossing it. I can always provide more details to
anyone
that wants them.

It's not rocket science to make these sort of things in a graphics package. I
used CorelDraw for this years ago, but now I'd look for an open-source
alternative. I've had non-linear scales, colours etc.
Personally I'd be unwilling to pay for such a program, but others might see it
differently.

It seems to me,
There was a program or two that someone (or more) had written to do meter scaling. It was designed to print properly on an hp laserjet as I recall.
At the moment am unable to find it in my list of links or programs on my computer. But Google should give some answers.

This probably should go on the HP_Agilent news group, but I was wondering if someone in this group had experience with rebuilding those or similar meters.

Thanks Bill the scale is fine. Its the meter needle that had paint peeling
off.
Just pulled the meter and removed the loose paint. Also just scanned the
meter face so in the crazy possibility of the decals peeling I can just
print a new face.
Now to locate a hobby store (that may actually be really tough these days.)
and find some enamel paint of approx correct color.
Kind of a florescent red and really a little dab will do you.

The biggest challenge is gently pulling the meter out and removing the

Thanks Bill the scale is fine. Its the meter needle that had paint peeling

Just pulled the meter and removed the loose paint. Also just scanned the
meter face so in the crazy possibility of the decals peeling I can just
print a new face.
Now to locate a hobby store (that may actually be really tough these
days.)
and find some enamel paint of approx correct color.
Kind of a florescent red and really a little dab will do you.

That you actually adjust it for peak signal through the 100KC IF.
Essentially disregarding slight literal offsets. (This is the same
approach
some navy receivers use back in the 70s, and some older ham equipment.)
The unit cleaned up very well though still have some tape glue to remove
and
label gunk from stickers.
The biggest challenge is gently pulling the meter out and removing the
peeling needle paint thats jamming the needle. No coffee during that
exercise.

I have had some success with putting the meter scale back down with
water.
It seems on some meters
that the scale was a decal that had a water based glue. I used a tooth
pick
to put a drop of water under
the part that was lifted and the used the tooth pick to smooth the scale
back in place.

I've posted the scanned copy of the manual on my website at<

Thanks for the interest, and the replies.

I've got a circa 1964 DY-5842 VLF receiver. This is (was) operated
in
conjunction with an external time interval counter to make a
frequency
comparison. So you would select WWVL for example, and use that as
your
primary standard for comparison to your local standard. It's got 5
crystals
in it: 16, 18, 19.8, 20, and 60 kHz (listed as GBR, NBA, NPM, WWVL,
WWVB).
It works and I have the manual. The thing is, the interest in
something
like this is bound to be a bit narrow, so I thought I'd mention it
here.
So if there are any collectors, equipment museums, etc. that might
be
interested in this, please let me know. I'm a bit sentimental about
this
thing, it's sort of a bit of history, and from what I can tell,
somewhat
rare (doesnt make it worth anything though :). Since it's a bit of a
curiosity, I'd like to pass it to someone that might be interested
in
it
rather than just tossing it. I can always provide more details to
anyone
that wants them.
Best regards,
Paul Davis - K9MR
Of course, that's the whole point of the web site :)

Boy do I agree with that.
If Diddier is reading this, wonder if we could add a meter scale to your
fine manual repository?
