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,

For those who operate 99.9 percent CW and don't even keep a microphone connected to their rig and whose rigs use the Kenwood style 8 pin microphone connector (I think it fits the 4 pin type as well bu

If anyone is looking for a nice little single band QRP rig, I have a QCX-Mini (version 1 but with the self destruct repair modifications installed and everything is working great) for 40 meters. I fin

Always happens. Got a phone call and I have had something come up. I'll probably get on later this evening when conditions are better anyway. Sorry about that. 73, Jim, W0EB
