Re: sBitx Logging issue - and Dupe Checking
Ashar,
you say that
"2. The other station replies back with your rst. Now that the reports are exchanged, you enter this in your logger and press the LOG button. The qso is logged."
When the connection is not completed because the RRR or RR73 confirming the reception is not received - then the entry saved in the log file should be deleted. Where can this be done?
Or some data is not correct and after saving it is still possible to see what needs to be corrected - but it is not possible to correct or edit the input saved in the log file.
Is there any concrete solution to this?
If this is the final log, then it's not finished!
Am I waiting for a solution or will the forum solve this too?

Re: sBITX Displayed Power and VSWR
@W9JES
I completely agree with you.
I only see the practice developed here, when someone needs help, then contact the forum.
When I noticed in May that I had the same problem, I didn't even try to contact support.
I knew I had to solve it myself, even though I also transferred $429, which was that much without rpi.
Unfortunately, they do not want to let go of this bad practice.

Re: sBitx V3 - TX output is fine but the SWR measurement is always 1.0
#sBITX_v3
#help
The one simple potential fix is to reflow the connections to L400 through L403.? There could be an open circuit in one of the connections.? It looks like it is easy to get to the connection from the top side of the board when it is installed.
IF you have two dummy loads AND a T connector, you can parallel the dummy loads to get a 2:1 SWR for testing.? Be sure both can handle the power.? Do this test at 50% or less drive.

Re: sBitx V3 - TX output is fine but the SWR measurement is always 1.0
#sBITX_v3
#help
If you have a good 50-ohm dummy load connected, the SWR should be 1.? Do you have a well-matched antenna to verify the SWR changes with frequency from the low end of the band to the high end?? At this stage, you do not want to transmit into a worse than 2:1 SWR.
If transmitting into a dummy load, try increasing the drive by 10% increments to see if the power goes up.? Monitor the current draw during transmission.? I would not go above 15 watts.? This is best verified with an external power meter.

Re: sBitx V3 - TX output is fine but the SWR measurement is always 1.0

My V3 is doing the exact same thing, no matter what band or antenna the VSWR shows 1.0, I changed 'bridge' from 100 to 70 with no change.

With just 4W the chances you'll get only 1.0 if the antenna is more or less well matched is very high. What is the real SWR and transmitted power read in a wattmeter?

Could I please get warranty support for troubleshooting my VSWR issue? The VSWR is always displayed at 1.0 on all bands and all modes during transmit. I own the v3 assembled kit, SN#? 559. I emailed sales@...?and Steve replied directing me to post the question on the forum hoping you will answer my question. Power output is fine and displayed correctly. The calibration sheet that came with the unit has no mention of whether the SWR was adjusted or checked. I read in a another thread stating that no calibration is required by the operator and that possibly the diodes are suspect? I checked user_settings.ini and it shows #fwdpower=0 #vswr=100 and bridge=100. Are these settings correct? Is metercal required to adjust the SWR reading? I haven't opened the sBItx yet to inspect the hardware or measure diodes.
Thanks

It's important for everyone to keep that in mind.? Pi 5 will need a newer OS than the one that comes with the sbitx boards, will need new GPIO code, etc.? Even though we're talking about it here, let's all keep in mind that this is currently advanced/experimental work.? Yet, as the adverts say, this product is designed for homebrewers/tinkerers so it's still a valid topic here. ? -- Regards, Dave, N1AI

Re: sBITX Displayed Power and VSWR
@Gyula. I completely understand the message. I just don't understand why the assembled V3 is touted as having a warranty and not getting a response from the manufacturer when there could be a hardware or software issue. My 30 day warranty will expire soon so I am left to resolve the issue myself? I am more than capable of resolving the issue on my own, however my SWR issue is a matter of principle at this point to hold the manufacturer accountable. I simply want the warranty support I paid for.

Re: sbitx with new Raspberry Pi 5 (updates)
Hi Dave,
Still to be done is the migration of the code to use the pinctrl's gpiolib API instead of WiringPi. I ended up testing with the command line pinctrl, but hopefully soon I'll be able to finish the code transition.
Cheers,
Rafael

Simple SDR Add-On for uBitX V6 and others
Greetings to all. I take no credit for this. This is just a rework of KD8CEC's earlier post to add an IF-SDR output to the uBitX series of radios. The V6 provides an IF output of 45Mhz at connector P3 (CW-1) which is well within the range of the inexpensive variety of SDR dongles on the market. In the case of the V6, I removed the USB jumper cable? between the Arduino Nano and the rear panel breakout and plugged my SDR dongle in its place. Simply add a short SMA cable from the 45MHz IF output to the SDR input and you're done. Take the mini USB you removed from the radio and connect it from the rear panel connector to your computer. Add free software and go. This is a great way to get your feet wet with SDR receivers without breaking the bank. In my case I had everything in my junk drawer. This mod can be applied to any of the uBitx series of radios or any receiver using an upconverting IF. Pictures are in the Photos section. I use SDR Sharp for Windows for the SDR software and Zadig for the dongle drivers. It runs great on my old junk. It also overcomes all of the shortcomings of the simple V6 receiver. Enjoy! Jim WB2LHP

or some tool that the dev team uses to keep track of new things??
Hopefully that would be the one...
I know Farhan is hard at work addressing many things, and he's mentioned several features that I'd like to see added, just don't want them to fall through the cracks.

Do you think that connector is some other bus? I hate the idea of using an external usb and hdmi cables to connect an internal display. Are we back to 1983 PC design?

Gyula - since the files I sent you early yesterday morning had a bunch of debugging info that is no longer required, recommend you retrieve the original two files from? the sbitx github then make the change to the one line we identified yesterday and re-build.
You're going to have to start at the beginning, and make 100 QSOs to verify the change....??? ;-)

Steve,
Sorry, I think the problem is that this morning I found a zip file in my account, I unzipped it and overwrote yesterday's. It lacks this override. :-(
