Re: [Elecraft] 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 Doug Joyce wrote: Ken / Dave: Just to let you know, I did this with equivalent / the same parts (I'll provide the part numbers I used later this AM) and at 20 ma fwd current they do indeed seem to all have equivalent brightness.

Re: [Elecraft] 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!) 73, Bill K9YEQ K2 #35; KX1 #35; K3 #1744; mini mods -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Dave Van Wallaghen Good morning all, I apologize for the late reply.

[Elecraft] 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.

Re: [Elecraft] 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. 73, Bill K9YEQ K2 #35; KX1 #35; K3 #1744; mini mods -Original Message- 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.
