David, The inside of the toroid should be hollow and it not hollow it should have as little in-fill as possible. This is the key to high performance 3D printed toroids. PLA or ABS are lossy and they

Hello everyone, My sBitx just arrived today, SN 44, and if course I tore it open like a kid on Christmas!? I already made a contact from inside my apartment with a mag loop - No mean feat here with

would not a simple tubing do the same?? .. the "shielding" of a coil wound on a ferrite core comes from the core material ... so i guess a normal pastic tubing will work equally well if not better

Dear group, I asked a friend of mine to build a master toroid stl file that we can put in our 3D printer software and come up with the plastic toroids almost any size we want.?? The Master was built

To add to Shirley's great response: When first released, the RPi 4 had heat issues, but shortly after the RPi 4 was released, updated firmware was released that corrected the issue. Firmware updates

I just finished installing the board... I found the patchy opinions/instructions difficult, and therefore am not entirely sure I have connected it correctly. No smoke, but I am also unable to get

Hi Shirley, thanks a lot for your answer. I checked the temperature of the Raspberry and that supports your opinion: 56c (133F) to 61c (142F) after running for about two hours seems ok Vy 73 de Rolf,

So my problem I suspect is in the transmit section of the Sbitx. I got out the schematic and measured dc voltage on the source and gate of Q9 IRF4905. They are both the same 13.79 volts. So perhaps

Well done.? Thank you Jim K5KKB sBitx 0016

The Raspberry Pi in the sBitx does not work especially hard. The processor gets warm but is well within specs. Mine has small paste-on heat sinks, but that's because I had already installed them when

Thank you so much, Farhan.? This is great!? I just received my Basic Kit. I'll wait for the upgrade before I put it together.? But I'll check out the boards visually :-)? If you can send an image

Thank you! sBitx #39 73 Goody K3NG

Thank you Ashhar - quite the gesture of support for your customers! 73 Lou KI5FTY

Where can I find parts placement diagrams for the main and digital boards, top and bottom? Or a photo of both bare boards? -Paul? K9MV sBITX #59

Hi all, After a spectacular flame-out of my power cable the other night during my S-Bitx metldown, I ordered the recommended power supply and some supplies to make a nice, new, fused heavy duty cable.

Farhan Will check current and get back to you. Screen doesn’t go weird. It just goes blank. Yes it reboots as if power is reapplied I have the basic kit - minus lcd and rpi Art
