DB-15 wired up to 5 Gnd and 15 +Ve and working well.
5V level at 4 & 6 GPIO is 5.07V - 5.08V checked on three different digital meters.
Not 5.1 or higher.
 
Audio cut-out problem still exists tested today on a mobile 2820, ID-51A and ID-31A.
 
Is there any way to build in a time delay for the UDRC to "hold the bus" before deciding the transmission has ended?
 
I can simulate the exact problem by un-keying and keying up again within 1 second.
The UDRC does not hear anything again until un-key or a pause of 3 seconds is received.
 
When using a DVRPTR it hears a break but waits and then carries on as if nothing has happened.
This tested with the same radio used for the UDRC hotspot FM-TX.
 
Running the UDRC from 12VDC is perfect for our battery backed up operation.
If you can crack the drop out problem will make it all come together.

The Buck Regulator on the UDRC-II is a TI design rated at 5.1V 3 amps continuous as recommended by the Raspberry Pi foundation. It Backpowers the Pithru an ideal diode and suffers no voltage drop due to using a cable to connect to an external Pi.

Power is on HD15-15 and SV4-15 (The header Field)
Ground is on HD15-5,10 and SV4-5,10,16

I recommend using it.

Thank you for your message.
 
I have a UDRC-II and Yes GND is on SV4 pins behind the DB-15 but +12v is not printed on this version.
Suspect it will be through plate hole 15 & 16 on SV4 but want NW to confirm this.

You can power the UDRC and Pi through the connect as you say. There is another option that works well. If you look at the board behind the DB-15 connector you will see two through-holes labeled: +12V and GND. You can solder wires attached to a standard barrel jack to these holes and power both boards with 9 to 14 volts. The voltage regulator on the UDRC is well built and very capable to back feeding the Pi and USB devices you have plugged in.

Great news, looks to me you connect 12VDC (13.8V) to DB-15 pins 10 & 15?
or SV4 Pin 15 +Ve and 16 Gnd? Which one is correct?
 
This will also give sufficient power for the USB DV3000 and USB headset microphone feed via Q4?

Hello NW Digital team.

Today I found what might be the reason for the UDRC cutout on RX.

I am still testing but have found a real issue with voltages lower than 5.1VDC when measured on the GPIO pins 4 & 6.

On the UDRC compass image I have installed DummyRepeater using the DV3000. 

This was done when the UDRC board was removed.

Two PSU's are available.

1) 5.0VDC @ 2.0Amps.

2) 5.1VDC @2.5Amps.

DummyRepeater fails to operate correctly if the PSU at 1) is used.

DummyRepeater works perfectly when the PSU at 2) is used.

Operating voltage of 5.15VDC between GPIO 4 & 6 is the best or possibly higher.

Please carry out testing on the UDRC and Pi3 to determine if the wrong voltage PSU is used can cause the RX drop outs I was experiencing.

If 4.9V is used for testing it might show the problem.

I will continue to test the UDRC over the next couple of days to prove this theory with my own variable PSU.

Amazed that 0.15V could cause the Pi3 to be problematic. I have been told that some of the Plug Pack PSU's can drop to a lower voltage or have poor regulation.

I will investigate a 13.8VDC drop down regulated 5.2VDC supply as an option.

The difference in 2.0A and 2.5A I cannot see to be a problem since the Pi3 running current is lower than 2A. On-board SMPS problem like the Pi2?

Looks like Pi3 VDC is critical and must be higher than 5.1V definitely for DummyRepeater and possibly UDRC.

Those wanting to use the Compass image with DV3000, USB headset and DummyRepeater must use >5.1VDC.

I tried three different 5.0V 2.0A PSU's and DummyRepeater failed to work correctly with all three but 100% as soon as the >5.1V 2.5A was used.

UDRC Compass timeserver error

John M Wysocki ZL2TWS <zl2tws@...>
 

 Jeremy

When timeserver is closed after running from terminal the following error is given.

pi@compass:~ $ sudo timeserver 1

13:39:18: Debug: 1 threads were not terminated by the application.

pi@compass:~ $ 

This should not happen.

Is this also related to the timercontrol problem?

You can also do this using the Pi itself, with a couple of SD-card-to-USB adaptors.

You can use the command line or Raspbian GUI tools that manipulate filesystems.

Re: Timercontrol

Dan Porter (AI2M)
 

Hi John,
I am successfully using the ircNodeDashboard with Compass Linux on a RPi 3 and the UDRC. I remember having a few issues at first with some updated file versions, but unfortunately did not keep notes. I’ll be happy to look at my system if it helps you out.
I also have the DG9VH dashboard installed on a RPi 2 with a Maryland Star image and DVMega. I previously used that ircddbgateway and just pointed the UDRC dstarrepeaterd to it. That way you can easily use some of the G4KLX utilities provided.

First I am here to help and want you to understand that this is not negative but more the facts of the matter and how I understand the situation. I apologise in advance if you think it is negative. Not intended to be.
 
There is no configuration file to find.
I have no idea what to do unless you give step by step instructions to follow.
 
Unfortunately compass is not fully functional in all aspects of G4KLX ircDDBGateway that are available with Western D-Star, Maryland, VK4TUX and home grown installations I made myself by downloading and compiling from github until you can fix this.
We only add features to D-Star software, not remove them.
 
I cannot get my favourite DG9VH dashboard to function fully unless G4KLX is all working.
John Hays recommended using his ircNodeDashboard.
I am fine with his idea and would like to have ircNode working with the UDRC Compass making this an all NW Digital installation.
 
ircNodeDashboard does not install correctly and I have tried twice on different Pi installations and it does not want to work from the instructions listed at GitHub. https://github.com/johnhays/ircNodeDashboard
I will need to start a new post on this subject later.
 
The problem for me is that only Compass works with UDRC so NW Digital have a monopoly on Compass for UDRC.
That is fine with me as UDRC is a NW product so NW have control of the software to use the UDRC.
 
It would be nice to have been able to add UDRC to my already fully functional G4KLX system.
 
I wait for your fix .
Here to help but you must give me step by step to be able to help you.
The timercontrol is missing so using -confdir is impossible until it is located.
No other instance of timercontrol can be found other than logrotate.d

I located the timercontrol file in /etc/logrotate.d and copied it to /etc/opendv.

That’s not the timercontrol configuration file.  That’s the log rotation file that tells logrotate how often to rotate the log files for timercontrol so that your /var partition doesn’t fill up.  You will have to create a configuration file to make it run correctly.

The same error message is sent.

Be wary of cheap micro USB cables, when the Pi2 came out power supplies cables I had that powered the Pi-B just fine would give the "rainbow square" in the upper right hand corner. That is a n indication of low power supply voltage. It turned out to be the voltage drop in the usb cables. Even a cheap 3 foot cable had .4 volt drop when powering the Pi2. Now I buy cables from Monoprice that are 20 gauge wire.

But the real answer is, the UDRC has a voltage regulator on it that can can take a 12 volt input and power the UDRC/Pi from that.

If you order a case from Budd Churchwood WB7FHC it has a "standard" DC power jack to use this feature.

First I am here to help and want you to understand that this is not negative but more the facts of the matter and how I understand the situation. I apologise in advance if you think it is negative. Not intended to be.
 
There is no configuration file to find.
I have no idea what to do unless you give step by step instructions to follow.
 
Unfortunately compass is not fully functional in all aspects of G4KLX ircDDBGateway that are available with Western D-Star, Maryland, VK4TUX and home grown installations I made myself by downloading and compiling from github until you can fix this.
We only add features to D-Star software, not remove them.
 
I cannot get my favourite DG9VH dashboard to function fully unless G4KLX is all working.
John Hays recommended using his ircNodeDashboard.
I am fine with his idea and would like to have ircNode working with the UDRC Compass making this an all NW Digital installation.
 
ircNodeDashboard does not install correctly and I have tried twice on different Pi installations and it does not want to work from the instructions listed at GitHub. https://github.com/johnhays/ircNodeDashboard
I will need to start a new post on this subject later.
 
The problem for me is that only Compass works with UDRC so NW Digital have a monopoly on Compass for UDRC.
That is fine with me as UDRC is a NW product so NW have control of the software to use the UDRC.
 
It would be nice to have been able to add UDRC to my already fully functional G4KLX system.
 
I wait for your fix .
Here to help but you must give me step by step to be able to help you.
The timercontrol is missing so using -confdir is impossible until it is located.
No other instance of timercontrol can be found other than logrotate.d

I located the timercontrol file in /etc/logrotate.d and copied it to /etc/opendv.

That’s not the timercontrol configuration file.  That’s the log rotation file that tells logrotate how often to rotate the log files for timercontrol so that your /var partition doesn’t fill up.  You will have to create a configuration file to make it run correctly.

The same error message is sent.

pi@compass:~ $ sudo timercontrol -confdir /etc/opendv

Rich,

Thanks for the help. I haven't really looked into audio levels settings since we only have the one complaint. But, now I will. Again thanks.

John, the ID-5100 is the pickiest on audio levels coming out of the repeater. I have found that with my ID-5100 I have to go into alsamixer and adjust the levels while listening on the ID-5100. I have to set PCM at 2db gain, ADC at -2 db gain and LO Driver at 0 db gain. I have an IC-7100 which is very tolerant of just about any setting, my ID51a+ is pretty tolerant but the ID-5100 requires these settings. I suggest setting them while monitoring on the 5100. BTW this is well documented on many different kinds of hotspots with the ID-5100, it is not a problem with the UDRC.

As far as our losing the last portion of every transmission I replaced the raspberry pi, loaded brand new image on the pi along with increasing the TX Delay and TX tail and have successfully eliminated the loss at the end of a transmission. We also did a factory reset of the DR-1X. We have discovered a couple of times the DR-1X would not respond properly to the UDRC and the only solution was a factory reset of the DR-1X which is pretty quick. The repeater is working great now.

Thanks for all the help.

I use dd to make the backups, and certainly I can muck with the
filesystem sizes, but it is just so convenient to just tell dd to copy
this file to this device with no messing around.  I suppose if I think
about it, a little bash pixie dust could automate the process tho.

Re: Pi3 PSU Voltage Critical

 

The UDRC has a 12vdc input which will power both the UDRC and Pi with good voltage and current.

Hello NW Digital team.

Today I found what might be the reason for the UDRC cutout on RX.

I am still testing but have found a real issue with voltages lower than 5.1VDC when measured on the GPIO pins 4 & 6.

On the UDRC compass image I have installed DummyRepeater using the DV3000.

This was done when the UDRC board was removed.

Two PSU's are available.

1) 5.0VDC @ 2.0Amps.

2) 5.1VDC @2.5Amps.

DummyRepeater fails to operate correctly if the PSU at 1) is used.

DummyRepeater works perfectly when the PSU at 2) is used.

Operating voltage of 5.15VDC between GPIO 4 & 6 is the best or possibly higher.

Please carry out testing on the UDRC and Pi3 to determine if the wrong voltage PSU is used can cause the RX drop outs I was experiencing.

If 4.9V is used for testing it might show the problem.

I will continue to test the UDRC over the next couple of days to prove this theory with my own variable PSU.

Amazed that 0.15V could cause the Pi3 to be problematic. I have been told that some of the Plug Pack PSU's can drop to a lower voltage or have poor regulation.

I will investigate a 13.8VDC drop down regulated 5.2VDC supply as an option.

The difference in 2.0A and 2.5A I cannot see to be a problem since the Pi3 running current is lower than 2A. On-board SMPS problem like the Pi2?

Looks like Pi3 VDC is critical and must be higher than 5.1V definitely for DummyRepeater and possibly UDRC.

Those wanting to use the Compass image with DV3000, USB headset and DummyRepeater must use >5.1VDC.

I tried three different 5.0V 2.0A PSU's and DummyRepeater failed to work correctly with all three but 100% as soon as the >5.1V 2.5A was used.

Re: Pi3 PSU Voltage Critical

Be wary of cheap micro USB cables, when the Pi2 came out power supplies cables I had that powered the Pi-B just fine would give the "rainbow square" in the upper right hand corner. That is a n indication of low power supply voltage. It turned out to be the voltage drop in the usb cables. Even a cheap 3 foot cable had .4 volt drop when powering the Pi2. Now I buy cables from Monoprice that are 20 gauge wire.

But the real answer is, the UDRC has a voltage regulator on it that can can take a 12 volt input and power the UDRC/Pi from that.

If you order a case from Budd Churchwood WB7FHC it has a "standard" DC power jack to use this feature.
