Re: DAYLIGHT RADIO - PLASTIC TOROID MASTER
Can someone tell me why a brass screw is used vs an iron or steel screw? I am sure this was explained years ago when these were first used but I don¡¯t have that information. I would think you would need iron to interact with the coil, but no science to back my thinking up.
Thanks in advance.

Re: sBitx Touchpad / Mouse Issue

I am very green with the desktop configuration as I have only used console terminal for all my work.?
.profile and .bashrc? are where you'd put commands that you want
to run upon >>user login<<.??
xinput is an executable file (program) that modifies the
established X windowing environment.
rather than wait until after the X environment is set up (for all
users), then modifying it via xinput (just for the user pi), you
could simply specify the desired configuration in the X windowing
initialization process.? (these rules are usually stored in the
/usr/share/X11/xorg.conf.d/ directory).

Hi

I'll have to find the appropriate files and add the command.?

Great!!! Using your rotator controller code. Now on the sbitx!!!

Re: DAYLIGHT RADIO - PLASTIC TOROID MASTER
It does look long enough to work. No, I have been trying for progressively thinner walls. Thanks for the encouragement.

Re: sBitx Touchpad / Mouse Issue

Scott,
If you're?using Linux, puting the command in .bashrc in your? home directory should work on?login. I'm using?Linux Mint, and it's called from my .profile file. The thing is, the command needs to be executed when the desktop is started.not on boot On Windows, which I haven't used for 20 years, you can put a batch (CMD) file in Autorun (Autostart?) to be executed on login.
Hey Ashhar (or anyone else),
I am uncertain where it would be best to add this mouse mapping to the RPI/sBitx boot sequence.? Can you make a recommendation?
Thanks, Scott

Re: DAYLIGHT RADIO - PLASTIC TOROID MASTER
Craig, why do you need a longer brass screw? The one in the picture looks long enough. Have you wound any coils with the printed toroid forms yet? From the picture, looks like egg shell.:) Barry K3BO ? Sent from for Windows ?

Re: sBitx transmit audio

This is self oscillating. Is your antenna properly tuned up? You might want to add a balun. I had this issue while using an external monitor. It vanished after adding a current balun : a couple of turns of the rf cable in a loop. - f

Re: sBitx transmit audio

Note you can use a kiwisdr near you to check the audio, very handy I have found!
This doesn't seem to affect the wind-like noise. Is it possible to purchase the mic you are shipping the complete kit with? I want to rule out the baofeng and qrpkits mics.?

I have several code updates posted in a fork (and within pull request #8), for anyone who would like to test drive them and provide feedback:
Notes on the various updates and features are in a wiki here:
The notes are a bit spartan at this point.

Re: sBitx Touchpad / Mouse Issue
#sBitx
In most Linux systems, you can add commands like this to the file /etc/rc.local and they will be executed on boot.
Hey ecc,
That was the solution!? It was pretty simple: tell the OS to only use the touchpad mouse on the DSI screen and every thing lines up.
In my case the terminal command is: xinput map-to-output "raspberry-ts" "DSI-1".? I'm pretty sure that once I restart the RPI that setting will be lost but this makes the touchpad useable in multiple monitor configurations.? I'll have to see how to make it part of the boot sequence.
Thanks for the help, Scott

Re: sBitx transmit audio
#sBitx
Try cutting down the mic gain. Probably the RF is getting into the mic line.
I got impatient and put one of these guys ()?in to replace the LM338 so I could run full power and it's working perfectly. I am getting audio reports of a "whooshing" noise on my SSB audio however, described as wind noise or as if I'm operating mobile with the windows down. I've tried both a Baofeng mic and a electret mic with the same results. Has anyone else experienced this? Any ideas on how to troubleshoot? I also feel like I'm hearing the same sound out of the sbitx speaker when I transmit. Unfortunately I didn't try SSB prior to replacing the LM338 so I'm not positive if that in any way contributes to this.?
Tried both USB and LSB on 20 and 80, same report. Made sure to turn off the wifi on the Pi as well. Mic set to 45 and Comp set to 40. It was reported the audio sounded great otherwise, not overmodulated, compression sounded good, just the addition of the wind noise.?
Running the latest code from github as of 8/23.
