Re: New Quadra-4 + USB dongle + WiFi
You¡¯re very Welcome Sean,
Thanks for your videos and a killer YouTube channel!! MERRY CHRISTMAS!!! -- 73, Danny Bush NF4J

Re: New Quadra-4 + USB dongle + WiFi
Thanks Danny! I'll have more out soon, I've just been waiting on a wsjtx update, so I can provide details on how to upgrade that (simple with the script w3djs wrote), followed by how to configure everything.
Merry Christmas W9fff

Re: cant find ardop executable
I had to build ardop for my Arm64 Pinebook Pro and Pinephone (same binary) from source. As I recall, prebuilt binaries didn't work for me on those machines.
I can provide the binary that I built upon request. I have not tried it on my new Quadra HamPi system yet, but plan to do so. Currently, the problem with ardopc is it doesn't work correctly with new-ish Linux kernels. More than one thread on the subject can be found in the ardop groups.io 73 Cal? AD8Q

Re: New Quadra-4 + USB dongle + WiFi
I've been a fairly heavy consumer of SD cards for Pine64 hardware for some time now. I used to have frequent trouble with SD cards until I adopted ALL of the Armbian recommendations:
Armbian can simply not run on unreliable hardware so checking your SD card with either or is mandatory if you run in problems. Remember, Quadra and HamPi OS are (were built with) Armbian! >It does mean something was written incorrectly, but in such a large image, that write failure could be anywhere...in somewhere critical or non-critical. Even if I somehow knew it was somewhere non-critical, I'd scrap it, because it could also be sign of a fake or poor quality and the faults may soon occur elsewhere where they ARE critical. 73 Cal?

Re: New Quadra-4 + USB dongle + WiFi
Balena Etcher does take forever but, mine does finally show verified and good. I just did this for the first time a few days ago and used the video by Ham Radio Dude on YouTube¡worked great!!

Re: New Quadra-4 + USB dongle + WiFi
When Balena Etcher reports that the flash has failed, what that means is that it makes a hash (fancy checksum) of the image it wrote and compares it to the hash of the source image, and if those two hashes (fancy checksums) don't match exactly, it reports the flash has failed. It does mean something was written incorrectly, but in such a large image, that write failure could be anywhere...in somewhere critical or non-critical. I'd be wary of using an image that failed. Getting reliable media takes a load off my shoulders at least. But, YMMV. On Sat, Dec 24, 2022 at 5:28 PM Bill K7WFB <wfbaron@...> wrote: I've had similar problems using Imager.

I've had similar problems using Imager. When I use Balena Etcher, it takes a long time and Etcher reports at the end that the flash has failed. I've found, however, that the flashed card works fine.

Re: Confused RE: How to re-image the Quadra
What size card are you trying to flash HamPi on?? It requires a minimum of 15.6gb...I use a 32gb card. And for the recod, HamPi/Hamclock is incredible!!

Re: Confused RE: How to re-image the Quadra
I forgot to attach the log of the failed RealVNC install.

Re: Confused RE: How to re-image the Quadra
When I boot Ham-Pi from the sd card, it looks like I have two separate linux boxes available -- the one with Ham-Pi installed and the one with the standard Quadra software installed. Is that right?
I installed RealVNC on the Quadra machine, and that worked well. Then I booted off the Ham-Pi card and my VNC client couldn't find either the Quadra box or the Ham-Pi box. So I guessed that I needed to install RealVNC on the Ham-Pi box, but the install failed. (See attached file.) Can anybody clue me in on what's going on here or what mistake I'm making. BTW, flashing the Ham-Pi image has been a problem for me. Win32DiskImager goes through the whole process, including a successful validation, in about ten minutes. But the cards don't seem to boot at all. Balena Etcher takes much longer (about 40 minutes including validation),? and then at the very end it says the flash failed . Nonetheless the cards work; i.e., Ham-Pi loads. In all cases, I have been booting with the video monitor attached.

Re: HDMI Recommendations
ve3ega
I power my whole cooling-stack off of 12VDC and use 'Buck Converters' to supply the different shelves (My QDX Radio is 9V, my Quadra(s) are 5V) my lights and Fan are also 5V but on a separate circuit.

Re: HDMI Recommendations
I wonder what the buck regulator is to go from 12V to 5V --

Show quoted text
alternatively, the boost regulator(s) to go from 5V to 12V. My guess is that the Quadra needs 5V for USB and other communication circuitry, and 3.3V and 2.5V for the microcontroller chip itself, and supporting circuitry. Thus, there would be a 12V -- 5V buck converter that is used if necessary, and a 3.3V converter that's always used, and if necessary there's also a 2.5V converter. Not that there's anything wrong with that, as long as all of them are digital (i.e. switcher) converters. If the 12V to 5V buck converter is an LM7805 or other linear converter, then a whole lot of that 12V juice is going up in smoke, lke 60% or even more, depending on the original supply voltage. And the required power budget in current always goes up as the voltage goes down. 73 Jim N6OTQ On Sat, Dec 10, 2022 at 7:29 AM Wes WB7BR <wesbflyer@...> wrote:
