After some outstanding drifts and latency on the sBitx, I realized the audio dsp and the alsa aloop were not locked. We need to use "timer_source=" parameter for the snd_aloop module to indicate the

Hello Evan, Which mod did you use to fix the uneven power output? Cheers Dean VK3DAE

Evan, Interesting point on using something around 15mhz.? Thanks for sharing that! 73 Mark -- AJ6CU KD8CEC 2.0, Nextion Screens,? and open source uBITX Raduino boards for Arduino IOT, BLE, RP2040,

Bryce, Yes, accuracy should be consistent across the bands assuming that you calibrated on one of the higher bands.? The error is multiplied as you go up in frequency.? The worst case would be to

Evan, After re-reading your post multiple times, I think it's starting to sink in.? Long story short, zero-beating is required because there are multiple variables changing simultaneously.? I'll

Another calibration video using the new Settings Editor and CEC V2 beta. https://youtu.be/7m4FttdHRCU You can then re-use these values in whether firmware you like. 73 Mark -- AJ6CU KD8CEC 2.0,

I use a Samlex 12A.? Its old school analog but portable its not as it weighs an easy 10 pounds. For portable LifFepo4 battery with fuses on the leads a 20ah unit runs it for a long time and weighs in

Ashhar - ?I changed my display name .

Bryce, Since all three clocks are changed when you do the calibration, adjusting to the first clock output does not ensure that the rig is calibrated (as your experience shows).? The other two can

We have used meanwell 12v, 10A smps with an added volt/amp digital meter.

Evan, Thanks for the response!? I have a 1.5GHz spectrum analyzer that I used as a frequency counter following the linked method above and then tuned the BFO (basically skipping step 1 in your

Hi all. I just want to quickly wrap-up this thread and give some feedback on how I fixed my rx problem. With a lot of help from Ashhar Farhan, Steve Beckman, Evan Hand, Petr Ourednik and Raj we could

What would be a good small "portable" AC/DC PSU for the sBitx? 73, Rafael

Which radio are you enquiring about?

Is there a way to enter frequencies directly. I have tried many things with no success, maybe there is no way to do this. thanks for any info Chuck K3etd

Thanks Evan, as always you are very thorough and helpful!

Hi al, Happy to announce the *first* beta of KD8CEC V2. The HEX files for Nanos can be found at: Release Beta 1 release of V2.0 for OEM Raduinos · AJ6CU/KD8CEC-V2.0-for-uBITX (github.com) (

Bryce, Thanks for the nice comments! Not perfect yet, the PTT connector was *supposed to be"? to trigger an external RF switch, but made the rank amateur mistake of not realizing the PTT signal was
