This was not a kit unit. But a unit purchased assembled at Hamvention.

You must do power calibration. Instruction on sbitx.net.

On 20 Meter FT8 I am only getting 7 watts output. Seem low to me. Yes the drive is at 100. I am using a PI4 with 8GB and running the 64 bit version. The antenna is a resonant 20 meter vertical.

Any suggestions

Re: sBITX 64Bit Pi Image Available #sBitx

 

Hey Gang..
Because this release was being packaged up as I was still finishing a few things, There is 'minor' update waiting in the repo for the FreeDV_PTT application.
One thing that will come along with this update is an upgrade.sh script that will make it easy to stay up to date with releases of this application.?

For just this one time we will need to manually pull the updated .deb file and invoke the update.

cd? ~\freedv_ptt
git pull
sudo dpkg -i freedv_ptt.deb

...and that should do it.
You'll now see an update.sh file in the freedv_ptt folder. any future upgrades will be done with ./update.sh

Easy peasy and thank you.

Not at this time. I will work on this in the future.

Can I upgrade with a direct order?


Re: sBITX 64Bit Pi Image Available #sBitx

 

P.S.

For those of you running DE hardware, I've also included the 3.01 sound file in the download folder and a script to "downgrade" and recompile the sBitx app.



To run this, open terminal and type:

cd Downloads
./DE_sb_sound.sh




Re: sBITX 64Bit Pi Image Available #sBitx

 

I published a new, preconfigured, Raspberry Pi image for the sBitx this evening.

This is the production version, code name, "Field Day".

?

sBitx 64 Bit Production Version 1 - Code Name "Field Day"

This is the production release of the sBitx 64 bit Raspberry Pi Image that is preconfigured with popular ham radio software including sBITX Toolbox, FreeDV PTT, and the sBitx app.?

What's New
Updated to the latest kernel (6.6.31) including all security patches as of 6.9.2024
sBitx version 3.025
Hardware RTC enabled
Version 2.06 version of sBITX Toolbox
Version 2.45 of FreeDV PTT by W2JON
GridTracker version 1.24.0512
WSJTX
JTDX
JS8Call
XDX
FLDigi
and more..
Additional tweaks and behind the scenes enhancements installed to improve responsiveness


I have been working with W2JON and included his application into the build as well. This is a robust version and includes his excellent product.

As a reminder, the current 32 bit version shipped from HF Signals and GigaParts is running "Buster". This version is no longer supported as of June 30, 2024. See ? The 64 bit version in this build is "Bookworm" and runs fine on all Raspberry Pi 4 platforms with the sBitx software.

Please see the instructions on the release page for details. ? The link to the Pi image is stored on my Google Drive in the link.txt file.

FT8 Power Pou

Re: Daylight again resurfacing

 

The Kits and Parts HYCAS IF amp has been installed into my partly torn apart Daylight Again and I am impressed! Per the information provide by John, KU4AF, on the amp matching of both the detector and crystal filter, was a big help. One change I HAD to make was to lower the gain of the audio pre amp that follows the detector, U4B. I reduced this to about 1/3 of the design value. Looking at the output waveform from? the audio amp, the signal is a pure sine wave with no distortion noticed. Sweet sounding audio too.
Now to layout the my construction mess to get the IF amp incorporated in the box.
Again, thanks to John, KU4AF.

Don’t want to pile on but I would really like the feet too. I don’t have access to a 3D printer. I will gladly pay for them and postage.?

Re: Low audio on new sbitx v3

 

My board has a bad and resistor going to the AF Amp. I am not at home to check the details but see
</g/BITX20/topic/105501603#msg110645>
You can check the voltage at the lm380 to see if this is it. Do you have lots of volume via the sbitx wen page?

Hello.

Got my new sbitx board hooked up and powered this week.

I am wondering about the audio. I have tried both hooking up a speaker and also a set of earphones but the audio is not that loud, actually can barely hear anything either way with the audio turned up all the way.

Using a regular speaker and a set of regular stereo earbuds.

Have looked at the drop down menu for the speaker output and that's at max.

Any ideas? Have looked in the online docs but can't find anything about what should be the norm for speaker.

Re: Low audio on new sbitx v3

 

If you want to know more, check the . The speaker is 8 Ohm, the maximum output power can be 2.5W. Pay attention to the supply voltage, because there will be no sound from the speaker below 10V.
Volume depends on a good antenna and IF and Audio settings.

James,

Increase IF gain if it is low.

Re: sBITX ToolBox 2.4 Problem

 

JJ THANK YOU a curiosity (I'll try it too), using "USB Headset" to record messages in "Voice Keyer" would be access to the recording level, Would it work?
