I dug my poor dusty MD380 out yesterday and charged it up. For a while now I have had Fusion and POCSAG on the pi-star but I rarely use the FT2D and when I do it’s only for APRS. So I thought why not get DMR back into the pi-star. I have a dual DVMEGA HAT with pi-star set to duplex from when I was fiddling with the new HAT.

Anyway, since I last used the MD380 I changed the rx and tx frequencies in pi-star to the ‘designated’ hotspot frequencies so the MD380 needed reprogramming.

That’s where it all started to go south…

First off, since I rebuilt the Windows PC I did not, for some reason copy across the MD380 programming software. Ok, found it on the web and installed it. Can it see the TYT programming lead? Nah. This particular lead is basically a wire, it does not have a chip built in apparently and so needs a specific driver. Oh yes, Windows will see the lead and knows what the device is but has no clue about the driver.

Ok. Found a driver. Installed it – apparently – it does not give an error but the rapidly disappearing screen on installation did not fill me with confidence. And no, it doesn’t work.

Tried another programming software suite called editcp (https://www.farnsworth.org/dale/codeplug/editcp/) in case that included the driver. Nope. The disk that came with the MD380, which took some searching as it is one of those small CDs and has nothing at all written on to indicate it is from TYT, also has the driver but it would not install either.

Right. Over to Linux. It saw the device and lsusb shows a reasonable text string. The same editcp software has a Linux version. And, typical of Linux it just works. It read the radio, allowed me change the frequencies and programmed the radio again, no issues (*). I did have to remember just how to set up the codeplug as I wanted to use both TS1 and TS2… that took a bit of head scratching as it’s been years since I fiddled with this. But a couple of useful websites (there are many others) helped sort my brain out and I now have pi-star and the MD380 set up for TS1 and TS2 with different talkgroups on each via the Brandmeister self service.

(* OK I’ll admit it took me five attempts to program the frequencies as I kept reading it wrong! FOUR times entered wrong before I got it typed in correctly)

I recently spent some time in Central Pennsylvania at my daughter’s house. Since I was going to be there a while, I brought along my Raspberry Pi hotspot. While I’m not really active in digital voice modes (or any voice modes, for that matter), there are a couple of DMR nets I like to check into each week. 

One issue I ran into in the past, is that my hotspot refuses to connect to their Wi-Fi network. Their Wi-Fi SSID has both an apostrophe and a space in it, so I’m guessing that’s the issue. I could have connected the hotspot directly to their router via an ethernet cable. Because of their router’s location, I would have had to move some furniture and put the hotspot in an awkward location. So, this time around I brought a little travel router to try another approach. 

Back when I was working, I had a TP-Link Nano router that I took on business trips. Typically, I would connect it to an Ethernet port in my hotel room to create a personal Wi-Fi network for my laptop and phone. A while back, I upgraded to the newer (and faster) TP-Link TL-WR802N travel router. I don’t travel nearly as much these days, so the new router hasn’t seen much use.

I brought the travel router along on this trip to create a wireless bridge from the house’s Wi-Fi to my personal Wi-Fi. The router’s Wi-Fi network has an SSID that my hotspot likes. I haven’t used that mode much, so I had to resort to the user manual to refresh my memory on how to set this thing up.

Actually, it was pretty easy to set up. It was simply a matter of connecting my laptop to travel travel router’s Wi-Fi to access the admin functions. From there, I set it up in the “Hotspot Router” mode. Then, I scanned to find the house’s Wi-Fi network and logged into it.

Testing the internet connectivity with my laptop, the speed looked good. I had previously added my travel router’s SSID and password to the hotspot, so soon after powering up I was hearing the sounds of DMR coming from my HT. This configuration worked great, and I successfully checked into a few nets during the week. 

The next time I go out there to visit, I’ll just need to power up the router and the hotspot, and everything should work. (Knock on wood)

No ground-breaking technological advances here. I just love when a plan comes together.

[Disclaimer: I have no monetary interest in this product, and there are no affiliate links in this post. I’m just a satisfied owner.]

Like many amateur operators, I have far too many handie talkies (HTs). I’ve cycled through many, and sold or given away many that I was done with. Some of those I wish I hadn’t sold (like the Kenwood TH-D74), but others I was glad to be rid of. I thought I would take a few paragraphs to talk about what I use day to day, and what I like and don’t like about these radios. I should note that I won’t discuss the HTs that I use in wildland fire communications as that is an entirely different purpose and topic.

On a regular basis and in addition to analog FM, I use DMR and Yaesu C4FM. To a lesser extent, I use P25 on amateur networks. Rarely do I ever use D-STAR any more, and then only via DVswitch and the mobile app on the phone.

I like using DMR. I’ve always liked the networks (specifically Brandmeister) and the architecture. I know, the digital audio is totally different than the richness of analog, but it’s still fun. And DMR was where I really learned about bridging and how I got into XLX reflectors.

For DMR, I mainly use the Anytone 878UV Plus II. I also use a Radioddity GD77 with the OpenGD77 firmware, and a Motorola XPR7550e. Of these three, I think the 878 is probably the best everyday choice. Yes, the 878 has its weird quirks, and the CPS (Customer Programming Software) is pretty bad, but the radio is fairly solid and easy to operate. And it sounds very good, both on receive and transmit. I also like the form factor and feel in the hand when operating. The OpenGD77 firmware is probably the most ham-friendly DMR firmware in existence, and is a pleasure to operate. But the hardware (Radioddity GD77) isn’t nearly as nice as the Anytone. I do like this radio as well, and keep one in the shed and use it while I’m out working in the yard. These radios as so inexpensive that you can have a couple and not worry about beating them up. In addition, both the 878 and the GD77 work very well with the Mobilinkd TNC4 for packet.

I don’t use the Motorola XPR7550e as much. It is a good solid radio, but is lacking a lot of the ham friendly features (like direct TG entry and persistence). I use it mostly on the Rocky Mountain Ham Radio region-wide DMR network where I am usually parked on one repeater/TG (Talkgroup) or roaming on a single TG.

For Yaesu C4FM (commonly referred to as “Fusion”), I use the FT-5DR. I also have an older FT-2DR, but it is relegated to my PDN (Personal Digital Node). The FT-5DR is a decent radio, and has a lot of APRS features. But to me, it feels pretty cheap. Indeed, mine has develoepd the dreaded case crack (or “mold line” as Yaesu likes to call it). It also goes through batteries very quickly. I always carry 2 extra batteries for this radio. I think my main gripes about this radio are the audio quality and the form factor. It does not sound very good, probably owing to the tiny size and small speaker. And it feels uncomfortable to hold an operate. I mostly use Yaesu C4FM because it is becoming more and more popular in our area, but I will admit that I am a bit of a reluctant user.

In my opinion, the Kenwood TH-D74 was the best APRS HT that I have ever owned. I should not have sold that. Kenwood’s APRS implementation and UI are much better than Yaesu’s, and the receiver in the Kenwood radios is much, much better than the Yaesu. I just wish Kenwood hadn’t gone with D-STAR as their digital mode of choice.

Finally, I use P25 a bit over a hotspot on amateur radio. For that I use a UHF Motorola XTS2500. I said I wouldn’t talk about wildland fire radios in this post, but I did it anyway. I also use this radio on fires, as it is one of the NIFC (National Interagency Fire Center) approved radios. This is a very solid older radio with great audio. The CPS is a real bear to deal with (read: it is horrible and not ham friendly), but the radio is awesome. On fires, I use it with a very large AA batttery clamshell that holds 12 batteries, but around the house I use an old rechargeable battery.

Anyway, as you can see I like HTs Maybe in a future post I will discuss some others, and talk about what we use in wildland fire.

A short while ago, the new Raspberry Pi Zero 2 W was announced. The original Pi Zero and the Zero W are widely used in MMDVM based hotspots and the new Zero 2 W is a direct, drop in replacement. The most obvious question is whether you need to replace your Pi Zero with a […]

 Release DVPI Version 1.03

There have been some changes to the DMR node recently.

This version changes only those related to the recently changed DMR node. If you normally use Version 1.0 or Version 0.95, no upgrade is required.

DVPi uses the USRP Client protocol. When you install and use DVSwitch, you must read and comply with the license that appears. The user is responsible for the license for the use of DVPi.

1.Download Link

https://github.com/phdlee/dvpi/releases/tag/v1.03

https://github.com/phdlee/dvpi/releases/download/v1.03/dvpi_103.zip

https://github.com/phdlee/dvpi/releases/download/v1.03/dvpimanager_103.zip

2.What was added in Version 1.03 (from Version 1.0)

 -To reduce user confusion, the MMDVM password change function has been removed.

  If the DMR's BM password has been changed, it can be changed on the DVSwitch Settings Change screen.

- It is not a function you use. Changed the TX/RX frequency of MMDVM to the same frequency. This is because the new DMR rule may not work if the frequency is different.

3.How to Install

  There is a detailed explanation about more detailed installation method and H/W configuration on my blog. 

  The following explains how to download and configure to use DVPi. Please refer to another post for more details.

3.1 Download

  Download the dvpi_103.zip and dvpimanager_103.zip files from the download link.

   Unzip the downloaded files (dvpi_103.zip, dvpimanager_103.zip)

3.2 Write the dvpi_103.img file to the SD card.

  Formatting the SD card is not mandatory. When I apply the image file to the SD card, sometimes an error occurs, so I format it first.

Apply the dvpi_103.img file to the SD card with Win32Disk Imager.

3.3 Find DVPi IP Address

The Raspberry Pi image used in DVPi is automatically assigned an IP (using DHCP Server).

You can use the DVPi Manager to find out the IP of the DVPi.

Run DVPi Manager -> Click the 'Find DVPi' Button

Click the 'Find' Button

(If multiple LAN cards are installed in your computer, you must select the IP address of your computer before clicking the 'Find' button)

I have 3 DVPi and they are all found. Once you have found the IP of the DVPi you can use ssh.

DVPi can be accessed with ssh id: pi, password: dvpi

Execute DVPi Manager -> Input DVPi IP Address -> Click the 'Connect' Button

Click the 'Easy setup of installed DV Switch'

To embed DVSwitch into DVPi, you only need to execute 4 commands. The four commands are explained in the center of the screen.

Rutn the SSH Client as putty

Login ID : pi, Passwor d: dvpi

Execute the commands described in DVPi Manager one by one.

It is convenient to use copy and paste.

In the case of putty, you can copy and paste multiple lines at once.

Execute 'sudo apt-get install -y dvswitch'

If all 4 commands were executed, your DVPi would have DVSwitch installed.

Setting up DVSwitch is easy with just a few entries.

Enter your callsign and DMR ID,

Unique ID is your Hotspot number that is unique. Any number you don't use is fine.

Choose Brand Meister Host, It is recommended to choose a server in your country.

(The US1 server that was set as the default until DVPi Version 1.0 is no longer operated)

If you have changed your password in Brand Meister, you must change the password field to your password.

The BM password can be changed here.

Enter the changed password.

Enter the Location field, the rest is not required, but it is strongly recommended to enter latitude and longitude.

Click the 'Apply All Setting' button.

The screen below is displayed and the operation takes about 1 minute.

When all settings are completed, the following message is displayed.

You can also check your Hotspot list if you log in to Brand Meister. I set the unique number 37 and it was displayed as follows.

3.5 flip the screen upside down

After rebooting, it will display normally as shown below.

3.6 Using DVPi

(For detailed usage and hardware configuration, please refer to other posts)

Reception is good. You have to test the transmission. If you are using D-Star, I recommend testing up to D-Star.

3.7 Dual Mode Settings

Connect to DVPi via SSH Client

Execute the setdvs2.sh command.

  (./setdvs2.sh new unique number, The unique number is the new Hotspot number.

  ex ./setdvs2.sh 38)

You can ignore the following error messages during script execution. (This is because it is a command to delete if it is already installed)

When all execution is completed, it asks if you want to reboot as follows.

No reboot required. This is because DVPi Manager will cause the DVPi to reboot.

Run DVPI manager

Click the 'DVPi Basic Setup'

After selecting Dual VFO as shown below, click the 'Apply All Setting' button.

(You may select 'Use Voice' if you wish to use the voice guidance function of DVPi)

When all settings are completed, DVPi automatically reboots.

After rebooting, DVPi operates in Dual Mode.

How to use DVPi's Dual Mode is described in detail in another post.

I tried changing the TG of VFO B.

3.8 DVPi's Hardware Settings

DVPi does not require any hardware other than the Raspberry Pi, sound card and LCD.

But for convenience, you can add things like buttons that you need.

How to add hardware to the DVPi is detailed in another post.

Run DVPi Manager

Click the 'Settings to use rotary encoder, PTT, and VOX functions' Button

In my case, I chose all of the below because I had a rotary encoder and buttons.

(If the direction of the rotary encoder is opposite, the numbers in the red square box below are interchanged)

When the activation selection for hardware is finished, click the 'Apply All Setting' button.

If the DVPi is equipped with a rotary encoder, it is possible to check who is in the TG as shown below.

4. conclusion

DVPi has quite a few features. In this post, I only set the settings for some of the features that are absolutely necessary for me.

You can find various features in different posts.

Release DVPI Version 1.0

Version 1.0 and Version 0.95 are the same. If you are using Version 0.95 you do not need to update to Version 1.0. 

DVPiManager has some features added. If you want to use features added in Versio 1.0, you only need to download dvpimanager.

DVPi uses the USRP Client protocol. When you install and use DVSwitch, you must read and comply with the license that appears. The user is responsible for the license for the use of DVPi.

1.Download Link

https://github.com/phdlee/dvpi/releases/tag/v1.0

https://github.com/phdlee/dvpi/releases/download/v1.0/dvpi_1.0.zip

https://github.com/phdlee/dvpi/releases/download/v1.0/dvpimanager_1.0.zip

2.What was added in Version 1.0 (from Version 0.95)

2.1 DVPi Manager 1.0 has added the ability to change the DMR password.

  Of course, you can change the DMR password using the DVSwitch Setup function in DVPiManager. But it will be a pretty long process.

If you have changed the DMR password in https://brandmeister.network/, you can easily change the DMR password in DVPiManager.

Enter the password you changed at brandmeister in the password field.

If you are using DVPi in DualMode, select both MMDVM_Bridge#1 and MMDVM_Bridge#2. If not, just choose MMDVM_Bridge#1.

Then click the'Change Password' button. Restart DVPi and your new password will take effect.

2.2 DVPi update function

If you are using DVPi 0.95 you do not need to update to Version 1.0. Just download DVPiManager 1.0.

But if you want your DVPi to appear as Version 1.0, click the Update button.

It automatically downloads and updates DVPi executable files from the web.

When all updates have been completed, the following message is displayed.

If you restart DVPi, Version 1.0 will be displayed. 

If the update fails, you can download the DVPi executable file below.

https://github.com/phdlee/dvpi/releases/download/v1.0/dvpi_up.zip

 Release DVPi Version 0.88 - Dual Mode, D-Star, Function Key 2

DVPi uses the USRP Client protocol.

When you install and use DVSwitch, you must read and comply with the license that appears.

Version 0.88 is a test version. If you want a stable version, please wait for Version 1.0.

1.How to install

Download : https://github.com/phdlee/dvpi/releases/tag/V0.88

Please check the previous installation documentation for detailed installation instructions. This post only describes what was added in Version 0.88.

http://www.hamskey.com/2020/08/release-dvpi-07-1installing-on-micro-sd.html

2. What was added in Version 0.88

2.1  D-Star protocol 

    You can use D-Star only by checking whether to 'Enable D-Star' in DVPi Manager.

If you are already using D-Star, you will not be able to use it on two at the same time. If you want to use D-Star in DVPi, you need to log off in another device. If anyone has solved this problem, please tell me.

2.2 Dual Mode

You can use two VFOs in the same way as a conventional VHF/UHF transceiver.

You can use two DVSwitch servers or DVLink. Or, if you operate DVPi as Standalone, you can create session 2 by copying the existing installed DVSwitch in DVPi.

If you are using DVPi stand alone, just run the setdvs2.sh command to copy the DVSwitch installed in DVPi and add a new session.

Unique ID values must be entered differently from existing values. 

Example)

 Session 1 Unique ID is 51

Sesssion 2 Unique ID is 58

In order to distinguish Hotspot in DMR network, you must use different Unique ID.

Select Dual VFO in DVPi Manager.

It will operate in Dual Mode as shown below.

Important Point: If you use DVPi stand alone, D-Star only works on VFO A.

The video below shows how to create Session 2 by copying the DVSwitch installed in DVPi and operate DVPi as Dual Mode.

2.3 Function Switch 2

  Function Switch2 can be used as Mode change or VFO change according to your selection.

Example of using Function Switch2 as a mode change switch

3.conclusion

The host.brandmeister.network server is not serviced, and the entire Talkgroup status can no longer be retrieved. So, the underline of DVPi's Talkgroup Button is disabled.

I'm trying to restore that functionality in Version 0.9. If we connect to brandmester.network directly, it will generate quite a lot of traffic. This is a problem for us as well, but it could also cause problems on the brandmeister.network server.

So I am thinking of building a separate server to minimize traffic. 

Until version 1.0, we plan to stabilize without adding features.

Thank you for using and testing.

We are always grateful to the DVSwitch team for implementing most of the features.

 DVPi schematic final version

I know some nice PCBs are designed for DVPi. I also ordered 5 samples of the PCB designed by EA7GIB and recently received it.

However, I had to add one LED and one switch to the needs of users. But this is just an option. Add this feature only if you need it.

You must read the document below link before reading this document.

http://www.hamskey.com/2020/08/dvpi-hardware-expansion-ptt-encoder-and.html

This document is an extension of the document at the link above. Most of the DVPi's hardware is explained in the link above.

This document describes only recently added hardware.

1.Schematic

2.Added Hardware

2.1 Added TX Led (transmission)

An LED has been added to indicate TX (transmission).

This can also be replaced by the PC817, just like the RX Led.

It can be used usefully when using the PTT button on touch screen or Vox function .

2.2 Fun2 S/W

The final version of DVPi supports Dual VFO and D-Star.

Function 2 switch can be used in Dual VFO or mode change (DMR <-> D-Star) according to user's selection.

GPIO_FUNC2_TYPE=1 : Function 2 switch is used to change VFO (Vfo A <-> Vfo B)

GPIO_FUNC2_TYPE=0 : Function 2 switch is used to change Mode (DMR <-> D-Star)

3.Conclusion

Again, DVPi can be used without any hardware. Just, if you need, you can add any hardware you want as RX Led, rotary Encoder ...

Recently, the hose.brandmeister.network server went down. So, Talk group information is not displayed in DVPi. 

I'll wait a few more days and look for other ways before DVPi 1.0.

We can bring the Lastheard information from https://brandmeister.network/ but it will require quite a bit of network traffic. 

Let's find a better way together.

About DVPi Talk group status line

2.Status Line in Talkg group Button

The Talk group button contains a status line. Numbers 262 and 91 below are blue and the rest are gray.

Let’s explore if there are other colors. Talk group 914 is Light Blue.

The time displayed in'Last' is the last time the PTT was pressed in the corresponding Talk group.

4 Update of Talk group status

4.1 Automatic update of Talk group status

Talk groups are automatically updated on the Internet. By default, it is set to be updated every 1 minute and 30 seconds.

Connect to DVPi Manager as shown below and click the'Userful features' button.

The Update Interval value in the red box is the cycle to update the Talk group status.

Set it to '0' if you don't want to automatically update the Talkgroup status automatically. It may be better to set it to '0' if you have a bad internet environment.

The number '1' means 30 seconds. 

Set it to 4 if you want to refresh it every 3 minutes

Set it to 10 if you want to refresh it every 5 minutes

4.2 Manually updating the Talk group status

If it is set not to be automatically updated or you want to know the Talkgroup status immediately, click the'TG Info Get' button below.

 

5.Updating user information

If there are many users who are not displayed as a call sign as shown below, please update the'User DB'.

It is recommended to update the'User DB' at least once a month.

DVSwitch installation is complete on your Raspberry Pi.

Installation is very simple. This is the dedication of the DVSwitch developers.

If you get an error while installing DVSwitch, try it elsewhere. I've found a few cases where it doesn't work depending on your internet provider.

2.3 Setting up DVSwitch

There are only two that you must enter.  However, it is recommended to enter additional information.

Enter your Call sign and DMR ID.  You can create a DMR ID at the site below.

(https://www.radioid.net/register#!)

Do not edit the Unique ID. However, if you use two or more Standalone DVPi, please enter different values.

This is the value by which the DMR network identifies your device.

There is no need to modify this part either. However, if you change to the BM server closest to you, you can use a much more stable DMR.

Click the 'Find BM in my Country' button

Select a server in your country or region close to you and click OK.

This is the information displayed to other users. If you enter your latitude and longitude, and your city and country, you will be a good DMR communication.

If you don't know the latitude and longitude of where you live, open Google Maps and click the mouse. The latitude and longitude of the clicked place will appear at the bottom.

When you have entered all the values, click the'Apply All Setting' button.

You will see a message similar to the one below.

When everything is done, the Raspberry pi reboots and all connections are disconnected. Don't worry, it's not an error.

The SSH terminal will also display a message stating that the connection has been lost. This is also not an error, so don't worry.

3. Standalone DVPi (Builtin DVSwitch)

When rebooting, REGOK will be displayed as below.

I changed the Talk group to 91. The communication tone was immediately received.

If it is set for the first time, there are cases in which you have to press PTT once to operate normally (your information is registered in the BM server)

Congratulations. Now, with only one DVPi (DVSwitch Builtin) , DMR communication is possible anywhere with the Internet.
