BRARA Net Update – 145.29 moving to 146.82
The BRARA 145.29 repeater located at the Social Security building in Boca Raton FL near RT95 and Yamato has been experiencing audio issues for a few months.  Given this, the two nets that occurs Monday on that machine will transition on a temporary basis to the GCARA 146.82(-) PL110.9 repeater located near the Boca Regional hospital in Boca Raton FL.

Please note the new BRARA DMR repeater is behaving just fine and can be used by those with DMR radios locally on TG-311027.

From this past Sunday net a few very informed DMR technical experts suggested anyone using a mobile DMR hotspot such as a Pi-Star to use the Texas server 3102. The reason is this server is much more stable and not experimental like some others.

Please read Bernie’s BLOG post on further details that applies to us all.

WHAT IS TGIF TALKGROUP

On Fridays at 8.30ET on TG-31665 is the TGIF Net. In order to participate, you have to change you pi-start DMR Master from 3102 to TGIF_Network om the drop down list and update your pi-star settings. Once the pi-star has recycled and is operating normally, connect to you hotspot on TG-31665 and enjoy the net. When you are done, change the DMR Master back to 3102. Have fun.

TGIF CONNECTION UPDATE

I reached out to one of my friends at BM to find out about TGIF. TGIF is not part of BM and is not on their network. They are apparently using a software made by Ty Weaver to host their system and a product called HB Link. The HBLINK is what allows your hotspot to connect to it and basically emulates a Brandmeister server type connection. This being the case the only way to reach their TG is connecting to their server or linking through someone else who has a connection.

Regards,
Bernie NY4Z

GCARA DMR REPEATER AND HOTSPOT PACKET DROPOUT
GCARA have adjusted their DMR repeater to use DMR server 3102. This should help reduce te DMR packet dropout. Our many thanks to GCARA and the group of folks who implemented this change.

DMR: Adding New TG and Channel

Adding a talkgroup and a channel to your codeplug using the software for your radio

After opening your codeplug software and reading your radio’s codeplug into the software save the file to your computer as a backup just in case then go to the talkgroup section. Scroll to the bottom and add the new talkgroup to it by clicking on the empty line and then entering the talkgroup number and assign a name to it and set it as a group call.

Adding a channel to your codeplug

Go to the channel section of your codeplug and scroll to the bottom and add the new channel to it by clicking on the blank line and then entering the needed information to cause it to be usable such as the rx frequency, the tx frequency, that it is digital, the color code for the repeater or hotspot, the time slot and the talk group name you want to access. Now go to the zones section and add the channel to the zone or zones you want it in. You have now added all the information necessary to be able to access the new channel from a zone or zones on your radio.

Write the new codeplug to the radio and check it out. If all went well and you can access the new channel and talkgroup you entered save the new codeplug file to your computer as your new codeplug.

Adding time servers to windows 10

To check the accuracy of the time on the computer goto www.time.is

If there is more than 0.5 second error then here is a fix.

Adding time servers to windows 10

Type “Control Panel” in Start search and hit Enter to open the Control Panel of your Windows 10 PC.

Type “Date and Time” in the search box and click on the result.

Click on the ‘Internet Time’ tab and hit on the ‘Change Settings’ button.

From the drop-down menu, select, say, time.nist.gov as the Server and hit the ‘Update now’ button.

If you receive any error, try using pool.ntp.org as your time server and then hit the Update Now button.

Make sure you select the checkbox saying, Synchronize with an internet time server.

Now Change time synchronization interval in Windows 10 Registry

A windows 10 computer synchronizes with a time server to update the clock at specific intervals. On stand-alone systems the update interval is 1 day. If you want your computer to synchronize the time more frequently, you can achieve that by changing the value for a registry key.

  1. Open registry editor. (Type regedit in the search box)
  2. Open the following registry path.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpClient

  1. Right click the key SpecialPollInterval and select modify.
  2. Select Decimal as Base. The default value in the Value data box will be 86400 which is the poll interval in seconds (86400 seconds = 1 day).
  3. Enter a new value in the Value data box. For example if you want to set the poll interval to two hours, enter the value 7200 or 3600 to set the interval to one hour.
  4. Click OK.
  5. Close registry editor and restart your computer.

DMR: Choosing a pi for your pi-star hotspot

Bud Talbot W0RMT

An important question to consider when building a pi-star based hotspot is what version of raspberry pi to use. You have three basic form factors to choose from: the zero, A+, and B+. The pi-zero is the smallest of these three, followed by the A+, and then the B+. The latest versions are the pi-zero W (or WH, which just has the header soldered on), the pi-3 A+, and the pi-3 B+. Other important factors to consider besides size are power consumption (very important for portable setups), boot time, wireless connection strength, and time required to switch configurations.

pi Specs

First let’s look at some published specifications for each of these models. Below is a nice chart from http://socialcompare.com/en/comparison/raspberrypi-models-comparison

From this chart, you can see that both the pi-3 A+ and pi-3 B+ have quad core processors clocked at 1.4 GHz. The difference between these two computers in terms of system resources is the RAM: the pi3 A+ has 512 MB while the pi-3 B+ has 1 GB. Note that the A+ form factor also lacks the RJ45 ethernet port, and only has 1 USB port. Neither of these is really a huge limitation for a hotspot in my opinion. That said, I do like to connect my pi-3 B+ based hotspots directly to the ethernet when available. The pi-zero is much smaller, but also has only a single core processor clocked at 1 GHz with 512 MB or RAM. So we can expect it to be slower in terms of performing operations. But for that tradeoff, you should see significantly less power consumption. Another important difference is in the WiFi: the A+ and B+ support both 2.4 GHz and 5 GHz 802.11 b/g/n/ac protocols, while the pi-zero only supports 802.11n over 2.4 GHz. This is likely to be an important factor as well.

Testing Procedure

In order to look more deeply at power consumption, I set up a test where I compared the three different raspberry pi options (zero, A+, and B+) using the same mmdvm hat (an N5BOC simplex board) and the same instance of pi-star (v 4.0 RC3) installed on a micro SD card (Patriot class 10 16 GB), and using the same power supply.

I then measured voltage (V) and current (I) over time using a small, inline USB meter (the UM25C). One nice thing about the UMC is that it interfaces with a PC over bluetooth so that you can record V and I versus t and view a graph and output data on the PC. This is a screenshot of testing for the pi-zero:

For each of the raspberry pi models tested, I ran three trials where I booted the pi and let it run for 15 minutes. I set the pi-star image up for D-STAR, and used the voice announcement as my “ready indicator for boot time.” I recorded the following parameters:

  • Boot time
  • 15 minute capacity used (in mAh)
  • 15 minute energy used (in mWh)
  • steady state voltage and current
  • pi load averages at 15 minutes (1’, 5’ and 15’ loads- see this linkif you’re not familiar with these metrics. Remember the pi-zero has a single core while the A+ and B+ have 4 cores)
  • Temperature (open case) after 15 minutes. Note that future testing should probably be in closed case which is more typical of operation. But that also introduces many more variables for each form factor (e.g. air space in case, ventilation in each case, etc).
  • Wifi signal strength (in dBm – see this linkif you’re not familiar with this measure). I measured this as signal strength received by my Ubiquiti networks access point, as read through the Unifi interface. For VoIP protocols, we really need at least -67 dBm. A lower value might work in some situations, but we’d like to see this greater than -67.

Conclusion

So what’s the conclusion? First, let’s look at the data to identify some notable differences.

  • Boot time: the pi-zero is about 20 s slower than the pi-3 A+ and B+
  • Power consumption: the pi-zero uses the least power, but the A+ doesn’t use much more. The B+ is a hog by comparison.
  • Maximum current on boot: again, the B+ has the largest, but it is still under 1 A. This surprised me, as I expected maximum current draw to be greater.
  • Operating temperature: the A+ has the clear edge here. It’s not working as hard as the pi-zero (reference the load averages) and it’s larger board may dissipate heat better.
  • Wifi signal strength: the zero really lags in this metric. The A+ and B+ have a 10x stronger wifi signal. This is a big deal.

Bottom line: I think the pi-3 A+ is probably the best in terms of boot time, low energy consumption, operating temperature, and wifi signal strength. And in terms of form factor, it’s not much larger than a pi-zero. I think that once we see some good case options for A+ based hotspots, we’ll notice a proliferation of ham hotspots built on the pi-3 A+. I know I’ll be migrating mine over to the pi-3 A+ from the pi-zero’s. I do think the pi-3 B+ board still has great utility in situations where power consumption is not an issue, like on the desktop in the shack where you are likely plugged into mains power and might want to connect to the network via ethernet.

Thanks for reading.

Our Scheduled Nets

COORDINATED NETS BEING REFORMED
We are adjusting the content and format of the Monday night Voice Com net. This means shortening the NCS script and refocus on the net content. For example, we used to have checked in stations provide project updates and address questions. Please join us the next few Mondays as we poll those station offering ideas and feedback.

BRARA Net Update – 145.29 moving to 146.82
The BRARA 145.29 repeater located at the Social Security building in Boca Raton FL near RT95 and Yamato has been experiencing audio issues for a few months.  Given this, the two nets that occurs Monday on that machine will transition on a temporary basis to the GCARA 146.82(-) PL110.9 repeater located near the Boca Regional hospital in Boca Raton FL.

Please note the new BRARA DMR repeater is behaving just fine and can be used by those with DMR radios locally on TG-311027.

From this past Sunday net a few very informed DMR technical experts suggested anyone using a mobile DMR hotspot such as a Pi-Star to use the Texas server 3102. The reason is this server is much more stable and not experimental like some others.

Please read Bernie’s BLOG post on further details that applies to us all.

WHAT IS TGIF TALKGROUP

On Fridays at 8.30ET on TG-31665 is the TGIF Net. In order to participate, you have to change you pi-start DMR Master from 3102 to TGIF_Network om the drop down list and update your pi-star settings. Once the pi-star has recycled and is operating normally, connect to you hotspot on TG-31665 and enjoy the net. When you are done, change the DMR Master back to 3102. Have fun.

TGIF CONNECTION UPDATE

I reached out to one of my friends at BM to find out about TGIF. TGIF is not part of BM and is not on their network. They are apparently using a software made by Ty Weaver to host their system and a product called HB Link. The HBLINK is what allows your hotspot to connect to it and basically emulates a Brandmeister server type connection. This being the case the only way to reach their TG is connecting to their server or linking through someone else who has a connection.

Bernie NY4Z

GCARA DMR REPEATER AND HOTSPOT PACKET DROPOUT
GCARA have adjusted their DMR repeater to use DMR server 3102. This should help reduce te DMR packet dropout. Our many thanks to GCARA and the group of folks who implemented this change.
