No problem. These things happen. The kernel package version is different than the kernel version. Confusing, I know, but because of the package versioning rules and what gets installed, it pretty much

Actually, this doesn’t tell you at all if you have compass installed. The second field is the hostname of the machine. If you change it using /etc/hostname, it’ll end up being whatever you want. The k

It’s actually Anna or Annaliese now. Thanks! This means that your installed package for the Linux kernel is from Compass and not from the Pi Foundation. If it were from the Pi Foundation it wouldn’t i

What is the output of “dpkg -l raspberrypi-kernel”? I’m assuming that since you’re on kernel version 4.9 that you’re running wilderness. I recently made some changes to the repository in preparation f

Please note that there was a problem with the previous kernel package in wilderness. I have made an update to the package that should enable a fix for the issue. Once you update to the latest kernel p

I’m actively working on Wilderness to update the kernel to 4.9 and to, as requested, get the stretch packages put in. I’m not surprised it doesn’t work. The warnings about Wilderness builds have been

By all means, if you can’t get it to the proper deviation, use the PCM control. But, you’d rather cut the LO control to it’s full down position first, and then move the PCM down to accomplish your goa

Yes, 0dB should be multiplying samples by 1.0 essentially. I can’t tell you about Basil’s script or looking at spectrum plots. I have an HP 8901A that I use for setting deviation of my devices. What I

#udrc-ii

There’s not much analog there to deal with. If you need more range on PCM, you might be able to combine the default UDRC with the alsa “softvol” control (http://alsa.opensrc.org/How_to_use_softvol_to_

No, there’s no option for lowering the LO bias rail. I don’t have the datasheet in front of my, but I don’t recall a third setting on it. — Jeremy McDermond nh6z@...

#udrc-ii

LO drive controls the gain of the analog "line out" amplifier after the DAC. The PCM control affects the output of the DAC by itself. The PCM count control merely multiples the incoming samples by a s

Mike -- This is what the firmware is supposed to set up on boot. Any line beginning with ‘#’ is a comment and is a pin that we don’t care about for the UDRC. The rest have a comment on the right hand

This is just your grep command in the line above. ambeserver isn’t running. Something that you have installed is grabbing pin 7 on boot. It’s not dstarrepeaterd because we’ve told it not to start on b

Yeah, it appears as though you have something that’s setting Pin 7 to an IN pin instead of an ALT0. I wouldn’t think it’s switching to wireless. It certainly wouldn’t switch the pin to an IN. It’s ano

BCM is short for Broadcom, the manufacturer of the System on a Chip used on the Raspberry Pi. The IC itself has pin numbers that are used in the Linux kernel and Raspberry Pi firmware to identify the

The pull-up/down resistors on the chip are only active when the pin is in input mode. The firmware on the UDRC tries to set up the pin so that you don’t get this behavior, but unfortunately I haven’t

With regards to the pins that drive the AIC3204, you should be looking at the following. You can check these on pinout.xyz that shows you RPi 40-pin pinout as well as BCM numbers. When I talk about th

We do put special patches in the kernel for Ham Radio stuff. There’s already an AX.25 patch by one of our developers in there to fix some bugginess that was happening with paclink unix. If you send me

It depends on what you mean about the “raspbian standard command to upgrade the kernel.” In the olden days of the original Raspberry Pi, the Foundation released Raspbian where the only way you got a k

Look carefully at the schematic. Many of the pins are only used to bring out to the unstuffed headers on the board (labelled PI2 and PI3), nothing else. These unstuffed headers are so you can use all
