I was up late last night and saw the order desk was again opened for the Bayou Jumper.  I never thought I would want one until they were no longer available!  My friend Curt, KB5JO got an early one

Ge group I am pleased to announce that the latest version of the Bayou Jumper is Transceiver kit is back in stock. While everything around us keeps rising in price, we have been able to hold the

Thanks for all the info Jim. David Martin - NA1MH - Mountain Home, Ar. ----------------------------------------- Wherever I go, there He is.

Jim, Thanks. I was able to open all the F360 files. David Martin - NA1MH - Mountain Home, Ar. ----------------------------------------- Wherever I go, there

Some pictures of the center insulators - one for an SO-239 and one for a BNC connector. The blue one is for the SO-239 and the grey one is for the BNC. It was quicker to print them both at the same

Please disregard the Zip file in the original post. There are 2 problematical errors in the Center Insulators. The SO-239 mounting holes are too far apart and the BNC mounting hole is too small in

Jerry commented yesterday, "Does anyone see a roller inductor in the making???" That's most likely well beyond my 3D skillset, and making the reliable moving contacts would be a real challenge. But

As promised, here is a ZIP file of the Fusion 360 design files and the .stl. 3D printable files for the 40/80 trap dipole end/trap insulators, trap coil forms (Wind with 15 turns of #20 enameled wire)

Dave, I'm using PLA2 or PLA+ both which are much easier to print with than PETG or ABS and are virtually NON-Toxic (ABS sure isn't). I have found that the PLA2 and PLA+ both last quite well outdoors,

Do a google search on Fusion 360 for personal use and you should find their newer instructions.

Jim, what material are you printing with, PETG ??? I wouldn't use PLA, but ABS would last longer than PLA, but I think PETG might last the longest ??

Jim, I had the original hobbyist version and Autodesk said my "free trial" was over ! I tried to sign up again for hobbyist license and couldn't find a means to do it.

I will Joe. I have a couple more things before I post the complete package. I still need to design a center insulator to take a BNC connector and one to take an SO-239 before I post the

I hope you can post the STL files! This looks great! 73 de K0NEB

Jim G's work inspired me to work on a 40/20 meter trap doublet/dipole/inverted vee with 3D printed trap coil forms and insulators. I have the traps coil forms done and the end/trap center insulators

Hi Lloyd, I'm CPU limited and can't run the better CAD packages like Fusion360. So I've been using TinkerCad on-line, and it's been sufficient for most things I've needed. With Ultimaker Cura 4.6.2

Dave, Suggest you check again, Fusion 360 is still free for personal/non commercial use. I have been using F360 for 3 years now, legally licensed for personal use and have not had to pay a penny for

FreeCad is not as intuitive as AutoDesk Fusion 360, but I am unwilling to pay their exorbitant price for hobby use. I have been designing things with FreeCad [on and

Does anyone see a roller inductor in the making??? They are hard to come by these days and the last one I bought was for a club build project linked here....a LC matching network for end fed half

Hello Jim. Very nice work on the coil form. I test printed your .stl file and it came out perfectly. If you don't mind my asking which CAD application do you use? Some time ago I attempted a similar
