@Ashhar Farhan. I created a discord group for the sBitx radio's. There are about 40 people in the group now and I just started it yesterday. It is a much better place to chat than Groups.IO. We would

Mark T K8MST, yes lucky you...many did not have any papers...spent hours trying to run the calibration and txcal. Now we are in alimbo and do not know if we ruined the unit.

I feel lucky. Mine had reports in the box. Monday I used it out of box for SSB qso. Yesterday did POTA activation. This is amazing radio/computer! Mark k8mst

Mine did not came with any paper either. I assumed it needed calibration...now I'm afraid I screwed up the unit...not really pleased

Farhan, Where are the calibration parameters stored?? Is it on the ATMega or the Raspberry Pi microSD card shipped with the unit?? If the latter, then a new image would require a new calibration.?

Hi Farhan, Im a little confused, I received mine without report (#49) I have to calibrate it? 73 Patrick F6GWE ________________________________ De : [email protected] <[email protected]> de la part de

Ashhar, that would have been noce to know when I purchesed at hamvention. Nothing in the packaging told me that was already calibrated.. so now what do i do? Can I uncalibrate it? New image? Change

DON'T CALIBRATE! Sorry for shouting out, but the radios are shipped completely calibrated. You need at least an rf power meter and a dummy load. The calibration is only meant for people who were

After couple days here my opinion. Last post for the evening about my progression with the sbitx. I started with the original image that came with the unit. I played around receiving with no issues.

Joe - check the PTT circuit and compare with the uBITX. This might fo the job nicely. Pete, N6QW, documented the tiny circuit very

I created a Discord for sBITx. Great place to text chat, voice chat and share videos and pictures. Here is the link for invitation. It is a public chat. I can make private once we get people to join

Vic, It was the v5 code that transmitted a 10MHz signal.? The v4 still had the AM zero beating to calibrate it.? Regardless, Nick is using the KD8CEC firmware, which does not have the transmission

Nestor, The slides belong to QRPARCI, however, they haven a welcome policy to allow the presenters to publish their paper online. I will expedite this and publish it in a few days. I am still

On the V4 uBitX that is the way calibration works...it puts out a signal at 10mHz, as I recall, so you need to have it working into a dummy load and adjust i while listening on a separate receiver or

Good day to all Just a question as the daylight again the slides for bitx 23 are available? I really want to know the design process Thanks

Hi Yvon, The linked message from Gary Anderson pointed to a possible solution to your issue.? Here is the message content: Begin

You mentioned you tried several Pc's. Normally I would suggest re rooting and making really sure nothing is using that Com Port. Win versions tend to hang onto Com Ports. Triple check. Swap cables as
