Homebrew SBITX with Hat
#homebrew
#sBitx
#sBitx-hat
On his recent stop in Northern Virginia Farhan was gracious enough to give me one of the sbitx hats to use in my homebrew rig.? I replaced the homebuilt digital board that I have been using with the hat and it is working great.?
Here is . If you are thinking of home brewing an sBitx like SDR the Hat is the perfect starting place. 73, Dean KK4DAS |

Re: Scratch building
Hi Paolo,
Your TFT display issue is not exactly clear.? The I/O levels of the display need to match the I/O levels from your ATMEGA328.? You can run the ATMEGA328 at 5V or also at 3.3V. I assume you are running a 5V ATMEGA with no level shifters like what is done on the HF Sigs uBITX v6. In this case, you need to run the display's board VCC at 5V and bypass the 3.3V regulator by placing a short/jumper at J1. With overvoltage on the IC, it functions at 5V I/O levels.? (That comes at the cost of higher power consumption, more heat and shortened lifetime due to higher voltage and temperature.) (the other case where you bypass the regulator is when you wire VCC to 3.3V for 3.3V operation, i.e. your system doesn't have a 5V source)
The display board you have appears to be the correct one. If you tried the display board configured in a 3.3V configuration with 5 V I/O levels on the ATMEGA, you _may_ have broken the touch sense IC.? But a 'not working' touch screen could also be a calibration issue.? Run the touch screen calibration. I'm running 3.3V I/O levels on my v6. /g/BITX20/message/101562 links from my? voltage conversion notes. Regards, Gary |

Re: sBITX ToolBox 2.4 Problem
In the meantime, I realized that the On-screen Keyboard (matchbox kbd) does not work for me. Neither is Onboard.desktop. I haven't figured out why not yet.
In the SBITX-Toolbox64 apps folder, sb_vk (Voice Keyer) can be started from the folder, sb_ts (Time Syncron) does not work. ? -- Gyula HA3HZ |

That's what I did but after installing v2.4 64-bit ToolBox I don't have a voice keyer anymore!let's wait for JJ's answer. Only those who do not work do not make mistakes. The Keyboard link doesn't seem to work either. ? -- Gyula HA3HZ |

Re: sBITX ToolBox 2.4 Problem
Ioan,
do what i did: since Update didn't install 2.4, I uninstalled the old one first: Type: /home/pi/sBITX-toolbox/uninstaller.sh?? and wait for the script to complete Then I installed v2.4 64-bit ToolBox according to page 3 of sBITX Toolbox Guide v2.3_64.pdf: 1. Open the terminal application on your sBitx 2. click on Terminal icon 3. Type: cd $HOME 4. Type: git clone https://github.com/drexjj/sBITX-toolbox64.git 5. Type: cd sBITX-toolbox64 6. Type: chmod +x *.sh 7. Type:./installer.sh Your screen should look like this when complete. 8. Wait for the installation to complete then close the terminal. Glad everything went well. That is all. (in some places the 32-bit link is included in the pdf, this needs to be corrected.) -- Gyula HA3HZ |

Re: sBITX ToolBox 2.4 Problem
Hi Joe.
I corrected this in /g/BITX20/message/111687? I apologize for the error in v2.3. The upgrade function should now be working in 2.4 but you have to take additional steps as described in the post. Please see if this works for you and report back in that thread. Thanks, JJ |

Re: Daylight again resurfacing
John, that sure does and I appreciate the information you have provided. I made the changes to the HYCAS input as you suggested. I was thinking that the tuned circuit does not need to be there following the crystal filter as you mentioned.
The autotransformer is a good suggestion too. Thanks very much for the help 73 Barry |

Re: Daylight again resurfacing
Barry,
I've done similar circuits, interfacing a crystal filter to a JFET amp, but not the Daylight specifically. My suggestion was based on that experience plus looking at the Daylight schematic. As-is, the crystal filter is terminated by 1k in parallel with a JFET gate (also in parallel with the SA602 output but you're not changing that). So if you substitute the HYCAS with 1k and a JFET, you keep the filter termination unchanged. I don't think it's necessary to add a tuned circuit/matching network for the HYCAS input since the bandwidth is already set by the crystal filter. Such a network would step up the voltage at the HYCAS input, giving more gain, but it's going to give you plenty of gain anyway. For the HYCAS output, the T1 transformer's 12 to 5 ratio steps the 50 ohm output up to 288 ohms at the Q6 collector. That's in parallel with with 2k (R15) plus whatever for the AGC detector diodes. Since the detector input is 1k so you could rewind T1 for 12 to 22 turns. That's a lot of turns on a T37 core so I'd make it an autotransformer, 22 turns tapped at 12, with a blocking cap going to the detector. Hope that helps! John |
