W1 LED Part Numbers

I read a posting last month about getting the Digi-Key part numbers for
green and amber/orange rectangle LED's that will fit and have the same
illumination as the red LED's already installed in the W1.

Did anyone come up with those part #'s? Did they work? I'd be interested
in retro fitting my W1 SWR scale. The W1 manual only has the Elecraft
part numbers and no generic description numbers.

Thanks,
Dave W8FGU

Re: W1 LED Part Numbers

I am waiting on the same thing Dave as I installed the LED's which are
rather dim. It would be fantastic with brighter LED's. I leave mine in line
as it provides a quick visual between the K3 and the ALS 600, esp when I
just push the tune button in the bypass tuner mode. The K3 does the same
thing but I just love the LED's on the W1.

Dave: That was likely my post. I'll provide an update when I get a few
minutes tomorrow about the part numbers and the info re the relative
"brightness" etc.

Thanks a lot Doug. I really appreciate it. If I can get them to match right I'm thinking of offering them as an option with my W1 enclosure.

Thanks again & 73,

Re: W1 LED Part Numbers

I have a "set" of additional green and yellow LED's

from Scott at Aptos. He got them for me from the

stock bins and didn't include their stock numbers.

I'll light them with a PS and see if their all the same

brightness and take a photo.

They -should- be the same product line and therefore

light equally, I'd think. They're from the KAT-100

tuner.

Scott was at least receptive to making all the W1

kits with three colors of LED's.

73! Ken

Re: W1 LED Part Numbers

Good morning all,
I apologize for the late reply. I was up late last night during my shift
and the dog and I took a little siesta this morning when I got home ;-)

Just to add a little more info. I looked up the internal Elecraft part
#'s for the leds used in the W1 and the KAT100 and the red ones are
specified as different internal part numbers. I sat my W1 next to the
KAT100 this morning and indeed they physically look different also.

I'm not exactly sure, but I think the Mouser part numbers posted may be
the leds specified for use in the KAT100 and may be the reason they look
dimmer.

I don't want to duplicate any efforts here, so has anyone tracked down
the manufacturers part number for the leds used in the W1 from Elecraft?
If not, I can surely email Scott and see if he has one that we can cross
reference with Digi-Key. Usually, if you have at least some type of
manufacturer number, you can search for it on their web site. Or is that
what you already did Doug?

Thanks for the generous offers to both Doug and Ken for sending me some
samples. Maybe we can track this down a little further before we get
there though.

Thank you all for your time, I didn't realize this was going to take up
such bandwidth here. Hopefully we're getting closer.

Take care & 73,
Dave W8FGU

Re: W1 LED Part Numbers

I don't think anyone will mind the time spent on this. I looked in Mouser
catalogue and was unable to find specs for higher output green, yellow and
orange LED's. I did order the ones originally posted here and they are
installed. So, please continue on your quest and let me know if I can help.
I would love a replacement set match the output of the red ones.
Personally, I think the W1 is cool! Now if I could just add another row and
a remote pickup for my amp I would be sooo happy! Heck, this setup is easy
to see, lightening fast reporting even if it is redundant to all the rest of
the meters and readouts. Just plain cool IMNSHO (In My Not So Humble
Opinion!)

Re: W1 LED Part Numbers

I am not sure if they match the output of the W1's red leds. IF they do
perfect. Can anyone test?

Good information, Ken.

Last night just before crawling into the sack I realized another
source of the Elecraft PN's might be the LED's used in the power out
displays of the XVTR's. You can probably get them by downloading one
of the XV*** manuals.

Re: W1 LED Part Numbers

I just looked them up and they are the same Elecraft part numbers as
listed for the KAT100.

Just for clarity. The part numbers for the red LED's are:
KAT100, XVTR, XG2 etc - E570007
W1 - E570026

Hmm...

Well, if the red LED's are the only problem, then why not just replace
them too?

Well, that is certainly a good idea and a good option. (Not to mention consistent with the scales on other Elecraft equipment).

If we can't find the W1 led versions, that may well be the best option.
