Hi John, I tried the tuning page and also found it to be broken.? The Javascript is there; it's just not working.? HFSignals will need to fix it. In the meantime, I have used this free Windows-based

Thanks for the quick reply Dave. I have used the tuning aid before on my PC and had no problems. I will look into using another audio analyzer like you suggested. Thanks, Happy Holidays 73, John

Hi Al have you tried ./build sbitx ?? 73 Evan AC9TU

John, The tuning aid does not work with all browsers. The browser must be able to receive audio from your computer microphone. The graphic display will not show until mic audio is present. The graphic

Hi, Al. You are not the only one to have this issue. See message /g/BITX20/message/106074 for the answer. Also, I will note that there is a fix for this problem waiting to be pulled:

Hello group, I was trying to use the bfo tuning aid on HF Signal web site. The link takes you to the new HF web site bfo page but tuning aid doesn’t start or even show up. Is there a new link to bfo

The SMPS units I’m finding at 10A all say that you need to limit current to 8A continuous. Does the intermittent current draw from the radio work with these power supplies? -r Sent from [Proton

Jeff, That is not an easy question to answer. I discovered this much to my dismay. Firstly, the fuses don't go off instantly. They take time to heat up enough to melt and break the circuit. This is a

When I run ./build from the command line in the sbitx directory where I have the code I keep getting the following error message: gcc ; error: .c: No such file or directory I checked the build file

I second Dave's recommendation of libgpiod (https://git.kernel.org/pub/scm/libs/libgpiod/libgpiod.git/about/). It is open source, actively maintained, and endo

What size fuse should I use on the 12 V supply for the new V3 board?

David, You could be correct, though I have had at least one situation with noise in the audio through the radio and good sound from VLC. 73 Evan AC9TU

Two years ago when I started Pi development for HamSCI the pigpio library seemed to be the best pick. I found it complete, well documented and it works well. It has C/C++, Python and daemon

Thanks Evan, Your reply is very informative with respect to the problems caused by incorrect shutting down of the Raspberry pi, I have added a shutdown shortcut to the desktop to help with this. when

Hi Mike, The code for determining DE vs V2 is buggy IF you have installed a device as node 08 on the I2C bus.? If someone added the SWR/Pwr sensor to the DE, that would be the case. Regardless, your

John Terrell's recording of the sbitx DE sending CW (message #106651) nicely shows the relay noise from the DE while sending CW (even though he is illustrating a different problem). Gordon Gibby

Dave Agree on all counts. Thanks for the reply. Sent from [Proton Mail](https://proton.me/mail/home) for iOS

I am a huge fan of python in general and the pysdr.org web site in particular, but my experience mucking around with SDRs ran counter to this. Keep in mind that Python is inherently single-threaded

Based on what was said by the Pi team during the Pi 5 launch, I think libgpiod is the most prominent replacement for WiringPi.? Rafael said switching over to it would be easy so I think sooner or
