Hi all, A friend of mine just gave me a Kanga L.C.K. CW transceiver kit. Unfortunately the box does not contain any instructions. I searched the internet and found nothing on this kit. I would be very

Well let's not pit our superheroes against each other! On qcx I was saved by that wonderful manual, not paper but using those colors on a screen to place each part. When I had a missed connection, the

John: I have read in other MicroMetals literature that the maximum continuous exposure temperature limit for the plastic binders that hold the iron powder in shape as toroids is 128 degrees C. A lot

Hi All, I may not have asked the question very well. At the bottom of: http://www.amidoncorp.com/product_images/specifications/1-35.pdf is a table of extrapolated AC flux density limits for both iron

Page 36 to 41 has more depth and calculations. http://www.amidoncorp.com/specs/

John, Found this: https://www.daycounter.com/Calculators/Max-Flux-Density-Calculator.phtml W5USJ, EM22cv, QRPARCI #5422

Amidon documents maximum flux density guidelines in: http://www.amidoncorp.com/product_images/specifications/1-35.pdf is there a reference to a technical document which derives these max flux values?

OK.? I'll do it tomorrow as I awaiting a reply to the email. I will do a 1W as an example without additional add ons. Will include labeling after painting. Give me a couple of days to watch paint

Chuck, I'd be happy with general instructions on the technique. I'll be mentioning your lab notebook on my next live stream July 6 th! 73! Mark KA6WKE Website: https://www.ka6wke.net Live Stream:

When I bought a uBitX (semi)kit I had grown tired of cobbling enclosures and I bought the cheap Harbor Freight brake. I would have look up the specs but I think it is supposed to handle steel up to 16

Hey, I just signed the petition "Australian Parliament: An inquiry into truth in political advertising" and wanted to see if you could help by adding your name. Our goal is to reach 25,000 signatures

I typically make enclosures with galvanized steel. It is readily available because it's used in roofing, HVAC, and pretty much everything else. One drawback is that it doesn't drill as easily as

Mark, You're right.? I did not write it up in the lab notebook https://www.k7qo.com/lab.pdf and that is my fault.? I thought of it.? I thought it through. Just didn't type it in. And, just for

Thanks for the quick response Chuck. Not sure where this lab notebook has been all my life! It has a section on making enclosures out of PCB but didn't see anything about Al enclosures. I'll check out

I use 0.040" Al.? I have section in the lab book and in some youtube videos under K7QO. I use a cheap Harbor Freight brake, also documented in both of the above so that I don't want to take up much
