Hi Mark,Evan, yes , great, just looks like the job, also had a quick look at github and as you say, there also. Will be able to use some (I hope). grateful thanks yr help. No doubt i'll be back Art

Good deal. Two updates I’d recommend: In Corrupted sBitx – How to reset the settings.ini: Insert a carriage return bettor sbitx.git and cd: In Upgrading to switching regulator (Development

GREAT IDEA .. got my ser# 146 in western PA.. Took a minute to get past the WiFi Noise... still learning ... bill? ny9h/3

Often, much of our knowledge of sbitx is getting scattered into various posts. I have started www.sbitx.net where over days and weeks, we will cull information from the posts, etc. and put them in one

I have tried installing RF bypass caps on the LM380 inputs and output, but this did not eliminate the noise. . The easiest fix is to disable WiFi on the Raspberry Pi *sudo ifconfig wlan0 down * If you

Hi Rolf, I am looking for a new place to live. Thank you for the information. I don't know of any stations in Japan that use sBitx, so I was troubled by the lack of information. Best regards.

OOOPS; I forgot.. blu capacitor are for teast, wayting polystirene capacitors, 6mm diameter brass bar, etc...

Hi Farhan, what a pleasure ! In attachement a pic of my PCBs. My PTO has a coil 30mm long , 9mm diameter, 10+30 turns? for 1.997 KHz without brass inside, turns are 24mm long. What the dimension of

Thank you for the explanation.? Have you had any issues with this regulator using the full 40 watt output?

Believe these are the same as the one that Evan shared but they are also here.

Actually, maybe that capacitor is an added part that was found necessary for stability of the LM338 (bypassing that leg of the voltage divider) and isn't on the schematic; there is also a largish

Come on in. The water is great, once you get used to it :-D

Hi Goody (and Ashhar), No need to apologize. ?I asked. ?Thank you very much for the guide/details. Ok… time to jump. Geronimo!

OK. It was unclear from the lengths of the leads on the regulator where exactly to go. That point was the closest ground I could find, and have the white and red leads still reach the LM338 location

Agreed; I’ve been running off of Ethernet. I do all my development work via SSH and VNC. Networking is a must! :-)

Hi Shirley, Thanks for posting your experiences with this upgrade. My rig has a 47 uF cap in that spot as well, not 470 uF as is on the schematic. I think it would be easier for folks to cut out the

Sigi, You can easily blow the pi, display and the digital board if the ground is not soldered firmly. - f siegfried.jackstien@...> wrote:

Paolo, Perhaps, the inductance is very low. What is the diameter and length of the tube that is used to wind the coil and how many turns have you added? A picture will help. - f

Hi, The schematic you can find here: https://github.com/afarhan/sbitx/blob/main/sbitx_main.pdf In the same directory there is the schematic of the digital part as well. You can find a detailed

I've built my own PTO without 3d printer. I used? 4 small PCB boards (25x20mm) using a 9mm diam. old? pen and 2 nuts soldered. Instead of common nuts I used 2 parts from Fisher gussets diam 6mm. I
