I don't have my sBitx yet, but having read Ashhar sbitx source code, there is no pulseaudio or jack, just pure Alsa, which is enough and indeed, the best solution to keep the audio stack clean, with

Thank you!? This is good info.? I thought the extra memory couldn't hurt but wanted to make sure. The only semi-free Pi I have is a 4 with 4GB.

I also built the excellent Emtech ZM2. One thing to remember with the sBitx is that the power out can be way above QRP tuner limits. For example the 4SQRP tuner limit is 10 watts, easily exceeded by

Hi Ashhar, What method do you use to route the audio internally on the RPi for third party apps ? I know there are a few options to do this such as pulseaudio and jack and so on but it would be good

Hello Somnath, Please contact support@... and send us the transaction details and I am sure we will be able to help you. Thanks, Thomas -- *Support@HFSignals*

Today i received the Antuino, switched it on and there is only a green screen. Really frustrated.

?Aaron, You will be very happy with your 4SQRP tuner. I built one and it was as good as my Emtech and other QRP tuners. I had too many that I have built over the years so I gave it away. Reading

Dave, If you see the first video, you will notice that as soon as the cw signal is filtered in, it has no ringing and weak signal is an armchair copy. That took some doing. The rx qudio is pleasing

Asher, These words “ We must make this easiest radio ever. Think sedan instead of an F1 racing car. Radio manufacturers have long forgotten the art of making comfortable radios like the Drake TR-4s.

Alan, The "Development Edition" is a bit of a misnomer. It doesn't mean that there are big bugs. Rather, this version is all large PCB and configured with all the tools needed for builders and

Ashhar, I have to hand it to you.. that is one beautiful looking radio.. I am going to wait for some of the bugs to work their way out of it but there is going to be one of those in my future I hope.

I recorded a video of FT8 operation with the sBitx. it is here: https://youtu.be/FHTUZwN7tAc

Jack Wow you are quite the wizard with coding, construction and maybe parts sourcing. Thanks for showing. Yeah the best variable capacitors might be as old as us. I didn't want the perhaps more recent

Curt: I've been reading a lot of posts about antenna tuners and I've looked up what they cost. Not cheap by any stretch and most are 10W max! As I recall, this one: cost me about $40 to build, but I

Aaron I confess I routinely operate into something like 1.6:1 especially if I know the feedline has a reasonable loss to the antenna. One of my antennas is an EFHW. Do gather its SWR across bands so

John, You must have seen that the video has a jump at 8:25. I switched to FT8 at that point, tuned around for about 2 minutes but 21 MHz was surprisingly quiet. I had to snip out that uninteresting

The display you are looking for is the official Raspberry Pi display; that's the one the kit is designed for. Digi-Key currently has a bunch of them: https://www.digikey.com/en/products/detail/raspber

Thank you!? This is perfect.

There is a link on this page. https://itshamradio.com/everything-you-need-to-know-to-build-sbitx-farhan/

I was looking over the Github site.? If we purchase the $299 version, is there an image for the Pi that can be downloaded and includes the OS and everything else, or do we need to load the RPi OS and
