Re: Changes to "LO Drive" in AlsaMixer Have No Affect #udrc-ii

Basil Gunn
 

My question, why do my
output sound levels remain the same no mater what I set them to in
alsamixer?
I'm assuming you are using the mini din6 cable for the UDRC II & radio.
What radio are you using?

Changes to "LO Drive" in AlsaMixer Have No Affect #udrc-ii

DAVID BASHAM <davidcbasham@...>
 

I would like to measure and change my deviation using the the PI3, SEAPAC Compass Image, and UDRC-II.  I am running Basil's script "measure_deviate.sh" to generate an audio tone.  I am using svxlink to measure the deviation using a RTL-SDR Dongle.  Everything about that process seems to be working.  I get a deviation value of about 3900 and I hear a clear tone in a second radio.  What baffles me is that when I go into alsamixer and change the values for either PCM or LO Drive nothing changes even when changing the values all up and down the scale.  The deviation stays the same and the tone I hear in a second radio sounds just the same.  I can make other changes in alsamixer such as muting the LOR Output and the tone stops so ALSA mixer is reacting to at least that change.  My question, why do my output sound levels remain the same no mater what I set them to in alsamixer?

Yaesu DR-2X with UDRC

Lot Marquez
 

Hi Guys, 
 Will the UDRC work the same way for a DR-2X?
We have the UDRC running the Dstar mode on our DR-1X Repeater and we now plan to upgrade to DR-2X. We would like to know if there would be any changes 
to setup or just plug and play. 

Thanks!

Has anyone noticed the tone encode on the dr-1x not come back after a dstar transmission. We had this happen today twice. And it took a few tries going between dstar and analog to get it to encode again. ???

WARNING: Linux 4.9 Kernel Impending in Wilderness

Annaliese McDermond
 

Dear Sports Fans:

In late April, the Raspberry Pi Foundation switched their default kernel from the 4.4.x train to the 4.9.x train. This is a fairly major change that was starting the testing phase in December. I haven’t heard any screaming from the RPi community, so it appears as though the 4.9 kernel is relatively stable. In keeping with this, I have started to merge the 4.9 code into the Compass kernel code. I have the initial work complete, and just need to test it in my lab a bit. I would expect in the next couple of days it will be committed to the udr/mcdermj branch which will be compiled into a new package for Wilderness. At this point, anyone who is tracking Wilderness will get this new kernel. While I do try to check these things out as thoroughly as I can, I’m certainly not perfect, and we’re a small development crew.

If you are still running Alder, you don’t need to worry about anything. If you’ve either upgraded to Wilderness or decided to take one of the “daily” images, you will get the new kernel. If you don’t want it for some reason, you’ll need to get instructions from somewhere on how to pin the current kernel package.

Re: UDRC-II as a Soft TNC

Edouard Lafargue
 


  Oh very interesting - I am using a radio connected to the DIN6 connector, so I have to use Channel 1 to connect to the AX25 stack in KISS mode. I had left Channel 0 unconfigured on direwolf.conf . When configuring Channel 0 for 9600 baud and 'N0CALL' for the callsign, then I don't hear my packets anymore.

   While I'm happy about this, I'm not 100% sure of what that is? Can you explain further, John?

Verify your configuration for channel 0 and 1 in direwolf.

Re: udrc-2 and gpio pins for fan power

 

First, for a dedicated radio server, I know of no apps that draw enough current to need a heatsink or fan.

But since you asked ...

On the 40 pin Header +5V is on pins 2 & 4 it is also available on the 26 pin expansion header. It’s easy to connect +5V to pin 4 and GND to pin 6 on the expansion header.

All of this is documented in the DataSheet

The UDRC-II regulator is designed for 3A continuous. The Pi takes much less than an amp and the rest is available to devices connected to USB as well as external uses.

if you search the web for pi temp controlled fan many people have done this.

To get the Pi’s core temp:

/opt/vc/bin/vcgencmd measure_temp

We typically see 40-45C for Ham appliances Max is 85C

Greetings,

I have a udrc-2 on RPi3, powered by 12V to the udrc-2. Through which physical gpio pin is the RPi3 powered please, pin 2 or 4 according to "gpio readall"? Would drawing some small current from one of these affect either the udrc-2 or the pi?

The question has to do with using a 5V pin for power supply for a small 5V fan that would use switched power from the pin to the fan according to cpu temperature.

I wouldn't be drawing power for a fan directly off a 5V pin. The
neighbours on that 5V bus may not appreciate the back-EMF the motor is
liable to generate even if the current draw is small.

I would suggest going a 12V fan, using a MOSFET gate to one of the spare
GPIO pins to control the fan. Then, the only thing that is likely to
get killed by back-EMF spikes is the MOSFET.

You can look on the schematics to find a spare pin that can be used for
GPIO fan control, perhaps PWM as well which means you can then control
the speed in software.

Re: RMS Gateway Configuration for UDRC 6pin Din

Basil Gunn
 

Thank you Basil!  I have read through the files you referenced
although I only understand about 1/3 of what they are talking about.
OK, keep asking questions & we'll see if we can't make it more clear.

In the file "ax25-upd"  I see the following text:
if [ "$UDRCII" => true ]; then
# use port 2 with mkiss
pseudoterm=$($SBINDIR/mkiss $SERIALPORT_DIREWOLF none /dev/ptmx | tail -1)
echo "using mkiss with UDRC II and pseudo term=$pseudoterm on port 2"
$SBINDIR/kissattach ${pseudoterm} ${PORTNAME} 44.24.197.66 >/tmp/ax25-config.tmp
dbgecho "kissattach return: $?"

Is the "port 2" in this text referring to the 6-pin connector?
Correct

Is this portion of the script setting the ax0 to port 2 assuming it sees a UDRC II?
Correct.
This script supports both original UDRC & UDRC II.

The syntax for mkiss is like this:

# This uses first port
mkiss $SERIALPORT_DIREWOLF /dev/ptmx none

# This uses second port
mkiss $SERIALPORT_DIREWOLF none /dev/ptmx

man mkiss gives a lot of information and I used the
"Configuring for Dual Port TNC's" section from here:

Re: RMS Gateway Configuration for UDRC 6pin Din

 

For the DIN-6 it only sets levels and turns on/off the audio streams -- logic levels (eg PTT) is up to the controlling program.
