I have found that using regular magnet wire with teflon tubing slid over the wire will easily handle 2KW. I have wound a number of 4:1 transformers as well as 49:1 transformers for EFHW using this

I was also surprised it broke down, but every CMC I wound with solid #12 enameled wire broke down between 400 and 700 watts. I believe it has a lot to do with the impedances in which the CMCs are

Generally, a few clamp-on ferrites of the appropriate material at the feedlint is all you really need. In that respect, even those ferrites aimed at EMC and RFI control are good for that purpose at

Hi, Dave Maybe QRZ doesn't like the docx format. Here's a PDF version for you to try uploading. This also cuts the file size down from 506K to about 70K. Mike K1YUP

CMC-VHF-UHF Has anyone done any work on VHF/UHF CMCs. power level 25W or so, rather than megawatt monster HF CMCs? There seems to be a lack of info on such items and on realistic power level [ie,

The Balun Designs bifilar-wound choke-baluns use #16 or #14 (not sure) bare wire slid into very small Teflon tubing. (I think Amidon has it). I use the 1171, rated at 5kw and 10kv -

Get a known standard, whatever that may be, a load standard, a short section of characterised coax etc and compare the results. What you are doing now is if I gave you an unknown weight and you

Don, Have you checked the velocity factor settings on the rig expert? Was your pc isolated from earth, ie a laptop. I've heard that an earthed computer connection has quite an effect. Just a couple of

I've had my H4 for a while now, and I really like it. I've been trying to get an idea of its SWR accuracy, so I compared it to a friend's RigXpert. I wrote an app that reads the RigXpert's

Thank you, Martin! Very nicely done!. Very thorough and comprehensive.

There are several programs for Windows (including 10), and one for Android. The SAA2 would be preferable if you need measurements above 1.5 GHz and/or need to use type N co-ax connectors. I believe
