Re: Quality USB-A to USB-C cable to avoid voltage drop
Hello Jeremy
My first question is:? Where did you buy the USB cord?
Also 5v 3a is right close to being not enough current for your
pi-4. 4-5a would be better. I mean by the time it reaches your pi
its at max 3a. I don't think it's your cord. 3ft should not* be
enough to shortchange you. That to me would not be that much of a
voltage* drop. Current yes by all means. 3a at 3 feet. That's
quite a lot. So up* your output current for the loss of voltage
from your 3ft cord.
Now have you tried to power this at home with a 5v wall wart with
that 3 ft cord?? I don't think it's the cable. Your right at the
edge of your current with the Powermax 5v 3a supply. Get my
drift?? Up your amperage and try again...
HTH? 73

testing here at home, using a 1ft long USB-A to USB-C cable,
it works without any problems.? But, I wanted a longer cable,
so I went to a 3ft cable from the same maker.? Once I used
that cable, I was immediately getting low voltage warnings ¨C
so obviously I¡¯m getting voltage drop on the longer cable.?

to avoid voltage drop across that length.

Anybody have knowledge of any good cables
that fit the bill???

Re: Quality USB-A to USB-C cable to avoid voltage drop
why not combine a buck boost unit close to the pi keep all the Rfi in a cage/rf bag then you feed 12v to that less drop?
Or hack up a higher watt c cable (Amazon Apple laptop charge cable for example)?into a solder usb end

When you connect to your IC7300 to your Raspberry Pi, do you:
? - See it's USB ports via the Linux command: lsusb
? - Do you have the right user/group permissions on the resulting
serial ports per:? ls -la /dev | grep ttyUSB
? - Are you running a version of Hamlib that supports the IC7300?
? - Can you control the radio via hamlib's rigctl program?
? - do you see the correct sound devices per: aplay -l?? and??
arecord -l

the fact that it does not work with some USB2.0 devices is the backwards?compatibility issue. The USB3.0 booting issue is the Pi's firmware (not the USB3.0, but the BOOT firmware) does not support boot mode in some USB to SATA chips.? Chips the manufacturers won't release the source code of their drivers so the Pi foundation can compile them into ARM architecture.? Yes, you are trolling, and that isn't allowed here.? If you want to troll, take it to facebook where everyone else is doing it.

I am not sure it¡¯s stable with new hamlib?code last time I had rig control working I had started with older hamlib had to compile up?
Vox works?
If you notice it won¡¯t say ¡°no rig I/o¡± on the splash screen?but it is connecting just won¡¯t do much more. (My experience anyway with a new compile)? Excuse typos and brevity, sent from a mobile device.

I had to compile from source. It was complicated as you say using instructions from the LOTW website.?

I think HamPi comes with TQSL, so there are probably binaries about somewhere.

I use HDD Raw Copy Tool (??) to make an exact copy of the SD Card.? It compresses the image on my Windows computer so it only takes space for the used part of the SD card.? I can then restore from the image to an SD card.? Note that the SD card that you restore to must be at least as large as the original SD card that you copied to an image file.

Yes.. they are available from the standard repos:
?? $ apt-cache search tqsl
?? libtqsllib1 - QSL signing routines for the Logbook of the World
(LoTW)
?? tqsllib-dev - QSL signing library development files
?? trustedqsl - QSL log signing for the Logbook of the World (LoTW)
Just do a "sudo apt install trustedqsl" and it should install.?

If you are copying an image to a SD Card, you don't need to format it.? The image overwrites all sectors.
There is also a backup menu item on PiOS which will copy the image from your SD Card to an attached SD Card.
You need Microsoft or Apple to use this. How much performance difference are we talking about? 73
