Re: sBitx transmit audio
#sBitx
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 On Tue, Aug 23, 2022, 11:57 PM Mark Earnest via <mark=[email protected]> wrote: This is what I'm hearing (recorded on a websdr near me) |

Re: sBitx Touchpad / Mouse Issue
#sBitx
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 |

Note you can use a kiwisdr near you to check the audio, very handy I have found!

In most Linux systems, you can add commands like this to the file /etc/rc.local and they will be executed on boot. On Tue, Aug 23, 2022 at 9:21 AM Scott KE8KYP <scott_massey@...> wrote: Hey ecc, |

Try cutting down the mic gain. Probably the RF is getting into the mic line. On Tue, Aug 23, 2022, 6:54 PM Mark Earnest via <mark=[email protected]> wrote:

sBitx transmit audio
#sBitx
Mark Earnest
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 qrpkits.com 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. |

Re: sBitx Touchpad / Mouse Issue
#sBitx
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 |

Rolf and Scott,
thanks for the reply. Yes, I was thinking of building the digital board on an RPi400, it has 2 hdmi ports. -- 73, Gyula HA3HZ |

I haven't tried it, but since the GUI seems to be built on X11, this approach should work: On Mon, Aug 22, 2022 at 6:39 PM Scott KE8KYP <scott_massey@...> wrote: Hi All, |

sBitx Touchpad / Mouse Issue
#sBitx
Hi All,
One thing I have noticed is when two monitors of differing resolutions are enabled, in my case the DSI and HDMI 0, an external mouse works fine on both screens in a typical "extended desktop" mode but the touch pad does not follow this mapping.? Although the DSI screen is working fine, what appears to be happening is the touchpad is mapped to control both monitors and not just the DSI display.? This appears to create a mapping error between the touchpad and the resolution of the DSI screen.? When the mouse pointer is moved by the external mouse and it transitions between monitors, it follows/translates the change in position without display errors.? By contrast, if you use the touchpad to move the pointer similarly, when you touch the screen, the pointer jumps to a position on the screen away from your intended touch. It appears that when two monitors are active, the touchpad follows the area combination of the two monitors and not just the DSI driven display.? That means the touchpad pointer does not align with the various functions and thus is unusable. ?I hope I made sense in describing the behavior.? Does anyone know of a way to correct this mapping issue or limit the touchpad mouse function to just the DSI display? Thanks, Scott?? |

Re: #sbitx mod
#sBitx
Hi Gyula,
If I understand your question correctly, if you do not use the DSI port, yes, you should be able to use the two (2) HDMI ports.? The RPi can support two monitor ports and yes, you'll need to supply a keyboard and mouse via a USB port to control the radio. Cheers, Scott |

Re: uBITX V6 Rigblaster PTT not triggering morse code but does trigger voice PTT

Not sure what you want to do, but if you want the pc to send Morse code you can use the mic input and select CW mode

uBITX V6 Rigblaster PTT not triggering morse code but does trigger voice PTT
#ubitxv6-help
I have an old rigblaster set up for digital work with my uBITX. Works great. I can plug it into the mic connector and it properly triggers PTT and plays audio.
However, when hooking the same exact cable to the CW input on the uBITX, the ptt does not trigger morse code. I can confirm it shorts the two correct pins, and when I plug in the hand-mic into the CW slot, the PTT triggers CW properly, however nothing at all happens with the rigblaster. Any tips? |
