Pi/DV4 mini powered by DeWALT 20v tool battery

The Pi/DV4 mini with my DeWALT 20v tool battery with USB / jacket adapter. That adapter comes with heated DeWALT jackets or hoodies to heat the jacket and provide 2 USB ports to charge cells while wearing the jacket.

DeWALT battery and USB adapter...

Here is DV4mini setup...

The Pi is now powered by 2a wall wart, but I have 12 Vdc adapter to go in a car or battery pack and I also have solar panel to charge up my battery pack that I made up years ago for all my radios to operate off the grid.
Here is the Pi / Dv4mini fully operational with wifi to hotspot on my iPhone

And all of it controlled by my iPad on the same hotspot from my cellphone.

Of course when at home I would not use my iPhone as hotspot by the house wifi or ethernet cable.

DV4 Mini pointed to a DR1x repeater

Does anyone have the fix on this problem below

We have multiple Dr1x's  with dv4 mini's pointed to them.  we have the   box checked and call sign inserted in the gateway box.  

The issue is the GPS  and call sign info does not get transmitted in DN   If we use VW the box then does pop up for a call sign but its blank. 

DV4MF2 Software and Windows 10

I want to climb out the walls with this DV4Mini and Windows 10. I took my Windows 7 x64 PC and installed the DV4Mini software according to the manuals and instructions on the various web sites. The original DG1HT software, DL2MF software and DL5KV software all work perfectly, 100% what is expected.

I also have a Windows 10 x64 PC and notebook. I also installed the DV4Mini on them according to the rules. The original DG1HT software and the DL5KV software work perfectly, 100 what is expected. The problem is the damn DL2MF software that keeps on giving me the error inside the attachment.

I even un-installed everything, I mean everything and started over from the beginning, still same stupid error. Google is not very helpfull either. Any working suggestions please in the group or by email will be highly appreciated.

dv4mini with Raspberry PI 3

I tried to install dv4mini on a raspberry PI in two different ways without success:

1.  From image file. When I load the image on the uSD card the RPi does not boot. I believe the image is only for RPi 2.

2. Install it from scratch: installed raspbian, apt-get upgrade and apt-get update,  apt-get install mono-complete. When I run sudo mono dv4mini.exe the dv4mini window appears briefly and then disappears. This message appears:

* Assertion at mini-codegen.c:807, condition `i == sel' not met

Any ideas?

On the menatime I have dv4mini running without trouble on a i3 desktop running  Ubuntu.

DV4mini setup

DV4mini setup

installed my DV4mini on a Raspberry Pi linked to a TYT MD-380 radio this week and they seem to be working fine together.  However, I hear very very little traffic, if any, from any reflectors, even when scanning via the DV4mini control panel.  I do hear a "Connected to xxxx" announcement when I connect to some reflectors, which tells me I am linked up OK and the dongle and the radio are communicating.  The dongle shows xmitting when I key the radio.

So, why am I not hearing any QSO's?

Question #2, What does the "Echo" icon on the DV4mini control panel do ? 

OK, a third Question.  What reflectors are generally the busiest?

DV4Mini When is the next update coming out? Dropouts and noises DMR

I was just wondering when the new update for the DV4 Mini is coming out. The Shark RF is out and they were able to successfully stop the noises on DMR. No I am not using a MD-380. and it drops out and makes noises on all radios. I listen to the Shark RF and dv mega's on DMR and they are all fine.

My internet connection is superb, been through all the adjustments on the software, tried firmwares from 1.60 all the way up to 1.66. Have two DV4 Minis and love my stick but starting to lose patience in DMR. Every other mode is perfectly fine.

DV4mini system

DV4miniI am fairly new to the DV4mini system but have had about a years experience assembling DVAPs around R Pi2/Star*Board/IC-208 hardware with KLX software.  I am considering trying a DV4mini using the R Pi2 but thought I heard folks talking about someone selling a package that consisted of the DV4mini, R Pi2 and software.  Did I hear correctly and who is the source if so?

Extended Routing in DV4mini

Currently the latest version of DV4MF2 BrandMeister can connect directly to the server. Through 4999 Reflector allows dynamically connect to other TGs form. Recall that now you can only connect reflectors from DV4mini app with this functionality we can connect to any TG (Talkgroup).

How to connect?

• DV4mini connect your server to a BrandMeister
• Select and connect to Reflector 4999
• Open a browser and go to the URL BrandMeister Spanish Extended Routing DV4mini
• In the form that appears we will see our UserID "214XYYY"
• TG write we want to plug and play !!!
• You are now mapping the Reflector 4999 TG9 our DV4mini

[DV4mini] dv_serial.exe has stopped working

I'm experiencing the following issue where Windows 7(x86) is reporting that the "dv_serial.exe has stopped working" after a period of working just fine for days.

In order to correct the problem, I find that I have to uninstall the com port (usually com3) in Device Manager and "Scan for Hardware Changes"
I can then reload the DV4mini control panel, and it works once again for an indeterminate period of time.

[DV4mini] error oxc000007b

I installed one second dv4mini in myself the first network uses an RPI and the second window 10 gives me this error always 0xc000007b, I do not think the problem is by using two dongle on the same network, any suggestions


I did a google search on this error code and found some solutions see if any of these help 0xc000007b Error Solution

[DV4mini] Hearing only one side of Conversation

I am using the DV4 Mini into the home computer, I am only interested in DStar transmissions as no radio for CFFM, P25 or DMR. I am using the v1.61 of the DV4 Software.

When listening for example to REF001C I often hear only one side of the conversants, sometimes neither of them! And I can check this by switching to my Raspberry PI/ DVAP set up.

If anyone else has encountered this and has a solution I would be delighted to hear from them.
