Clough-Brengle equipment web page
 

http://radioheaven.homestead.com/CloughBrengle.html

I've made a bunch of updates to the C-B page.
Check it out if you get a chance.

If you have any interesting C-B stuff I would really
appreciate some good photos to add to the page.

73,

Ron

Hi,

http://radioheaven.homestead.com/CloughBrengle.html

From here it looks like a page cut into a dozen parts with scissors
and pasted back together in random order.

Time to replace a few 01As in that old-timey browser, huh Alan?

It doesn't render all that smoothly for me but I'm not sure why not. I
think it has something to do with the large gif file being constricted
rather than resized beforehand which would speed up loading and
possibility eliminate the poor edging on the text.

I don't understand what the problem is.
The pages look just fine and load plenty fast,
not one of them takes more than 4 or 5 seconds
to fully open.
Maybe you guys are using some non standard
browser. All of my pages are optimized
for I.E.

Ron

It's just fine with me once I helped get the semantics and spelling fixed.
I'm not going to nitpick about the "gap" in the box on the right side where
the background unexplainedly shows between the text panel and the border. I
think it's an interesting subject and hope you'll add to it soon. Reed Park
and I think Lou G. want to add test equipment items to it and would be happy
to talk to you. I think it has a lot of potential good use. Thanks for
pointing it out to us!

Here's the same image after some tinkering....50k file size instead of
298k and it looks better to me.
http://www.sparkbench.com/CBtext1revised.gif

Not a problem for me, just a point of discussion.

Two things occur to me, Ron. First, only about 50% of web subscribers
are using 'broadband' in the US, and certainly less in the rest of the
world. So it still behooves one to opt for download time preference
where it is possible and its a no-brainer if the quality can be better
in the process.

Secondly, the format you are using constricts the image into a 'frame'
and on a common 800x600 monitor thats resulting in about 50%
compression. Might not look so bad on a 1024-wide format. Things like
this always look better when blowing upwards as opposed to downwards.
800x600 still seems to be the norm these days.

"What-you-see-isnt-always-what-you-get" when it comes to folks with
different internet connections, different size monitors, etc. I looked
at the home page in both Netscape 7 (Mozilla) and IE. In my Netscape
the "From a 1941 catalog..." is spilling outside of the box. Not a
biggie but you can see the implications with some of the IE-only webpage
designs. Optimizing for one browser only usually implies that it might
not work with others. No need for things to be that way when a page can
be made to work correctly on all browsers.

Regards,
Bill M

Optimizing for one browser only usually implies that it might not work
with others.

On Homestead you either optimize for Nutscape or I.E..
I use I.E., which do you think I'm going to pick.

Arrrggggh. Make that:

I need a URL validator. Or a brain validator. Or something.

Maybe a good, stiff drink.

Just finish it. If somebodies' browser ***** it up maybe they'll be smart
and read the INFORMATION instead of groaning about the format. I was pleased
to help. Nobody ever built their webpages based on anything! I have ever
said or done : )

Thats all well and good but the fact that you use IE doesn't restrict
you to webpage creation software that only works correctly for IE.
Its really a generic thing, not a matter of optimizing for one or the
other. Out of the 3 or 4 billion pages showing on Google only a small
fraction are "only works properly with IE". I've never seen a page that
"only works with Netscape".
Generic is best or we wouldn't be dragging out this thread.

I can see where you might get that idea -- one of the pages is a "collage" of
various photos (gear shots, CCC station pix, catalog snippets, etc.). But the
background framing makes it clear that's what you're seeing. Yes, the photos
do take a while to load, but the final result is excellent. FWIW, I'm running
IE and 1024 pixel screen.

As for GIF format, I DLed the blown-up copy of the transmitter schematic (wow,
a separate driver-multiplier stage back in those MOPA days). As a JPG it was
110 KB. I converted it to GIF and it went down to 13KB! Almost 10 to 1.

As for the gear -- I got a kick out of the TX with the plate caps on the output
coils for changing band taps. Neat idea. Luckily the power interlock switch
is also very clearly shown :-)

Now Ibelieve I owe some test eqpt shots -- Mike K.

Bill, explain to me what you did to get it so small.
I'm sure I'll need to do again for some future page.
I have some Clough-Brengle catalog pages that
I'd like to put on, but the scans are more than 2 meg.
and still are hard to read the small text.

Thanks,

Ron

I resized it to 500 pixels wide - it was 1083 wide so that alone reduced
the file size to about 25% of original. No point in having a 1083 pixel
wide image that has to scrunch into the box provided on the page. That
causes it to compress and may look 'funny' depending on a guys browser,
video card, monitor, etc. At 500 pixels maybe it still compresses (or
expands) a little bit. I can't tell from the script what the size of
the rectangle is supposed to be but on my browser it appears to be about
500 wide.

Next I took it down from 8-bit/256 colors to 4-bit/16 colors. As
mentioned before, thats a no brainer for a black and white image. That
reduces the file size even further. Then just for looks I changed some
of the 'almost' white or 'almost' black pixels to true black and white
leaving the greys in the middle of the range.

For your 2 MB scans try something along the same lines. If they are 2MB
it sounds as if they were scanned as color??. Get them into black and
white for starters and gradually step down to 256 and then to 16 color
black and white and see how they look. Old yellowed pages are sometime
difficult to handle but there's ways.
After you get it looking good, resize it down to whatever width is
appropriate for the page. If there's a lot of fine print you might not
be able to get it as small as you'd like. The alternative here is to
put a reduced size clickable link on the main page that can carry an
interested surfer to a full size version. That way the main info page
doesn't get bogged down.
Crop the edges appropriately. You can often knock off a bunch of the
file size just with simple cropping.
And if its a fine text page, don't try to put it in a box like the
letter on the home page because thats gonna really scrunch down the fine
print.

Hope this helps, drop me an email if you'd like to discuss it further.

-Bill, I scanned a Clough-Brengle model 110 catalog page,
it was in grayscale 300 dpi. The original scan was over
3 meg. I used Photoshop7 to reduce the from more
than 5K pixels wide to just 1000 wide. The file size was
reduced to about 125K and still looks great on the
web page. I may try going even smaller.

Thanks again.

If you had taken it all the way to 2 colors (B & W) the GIF compression would
really have been something. FWIW, the enlarged schematic of the 4581 TX
compressed instantly to 12K, though still 841x411. Although the original was a
full-color JPG, there were apparently only black and white pixels in it.

When converting to GIF, GIF has to figure out ahead of time how many unique
colors re in the image, and it quickly found there were only two, so it went to
B&W GIF, which is very efficient. --MikeK.

I tried. It started looking crappier rather than better. Thats why I
went after the 16 grey colors one at a time. Couldn't pull it off.

True, that usually happens to a scanned B&W document. If you reduce it to 2
colors, the lines and letters break up around the edges. Using 16 shades of
gray permits "aliasing" to fill in the breaks so the eye sees it as smooth.

You were right to stop at 16. I just wanted to point out that the typewritten
sheet in the home page really is already 2 colors (B&W), having been expertly
scanned and worked over by someone. Likewise the large schamtic for the TX.
Both these should make good 2-color GIF.

Er, I'm not really certain aobut the opening sheet -- but I did save and check
out the TX schematic, so know it's 2 color already, and compresses almost 10:1
under GIF.
