Building a Swiss Army Knife with the Inrico T320

This post is actually a combination of different “Tips & Tricks” I previously wrote in the knowledge base. I’m not going to explain all settings again. Just hit the tags in the sidebar most of the subjects discussed here are filled under “Button Mapper” and “Zello

Since a few weeks I’ve got this new found love for the first Network Radio I bought: the Inrico T320. As you all know, i’m a huge fan of Telo, I love the build, the audio quality, the design … and especially the big touchscreen. So for a while I was very happy with my TE-590 and I still am. But preferences changes over time. Ever since I started using Walkie Fleet at home and at work, I struggled with the dual app that needs to be configered: Zello for Hobby and Walkie Fleet for Work and Home use.

And now the thing that first led me away from the T320 is actually the thing that I most love about it: Its keyboard. I’ve found out that with most big touchscreens I often accidentally hit the screen and disable or enable stuff! The smaller screen on the T320 is less sensitive and in combination with Button Mapper I’m super fast in changing Apps, settings, channels, ….
So here’s a short description on how I set up my Inrico T320:

NRAPRS

Since NRAPRS is getting into a nice working Beta stage, it was time to update the manual section with a descent manual and how-to:
NRAPRS – Installation and how to guide

NRAPRS – Network Radio Tracking

For those who are not up to date with NRAPRS : on www.nraprs.be you can see a map where you can find, locate and track other Network Radio Users around the globe.

Crosslinking

There’s a moment in your Network Radio career and probably in your general Radio career as well that you have several different devices connected to different technologies or networks. This often results in dragging around multiple handheld devices to stay connected with your favourite fellow radio folks on their own networks.
We have Zello, ZelloWork, WalkieFleet, Real PTT, Echolink, PMR, DMR, … and so on.

Personally I have a private WalkieFleet Network for me and my family (Clan Caignie), a professional WalkieFleet network for my crew when at work and I use Zello to keep in touch with my favourite Network Radio buddies. So that’s three networks to monitor. Actually two, because when at work al the rest is shut down, to keep focussed. When at work i only run the Family WalkieFleet network on my Smartphone in case of emergency if my wife or kid is are in trouble.
So I end up with two networks that I would like to monitor at the same time, Zello & my Clan Caignie WalkieFleet network. And as we all know, most PTT applications are not social pieces of software. They all think they are the center of the “PTT universe” and claim the PTT button. I’ve written some articles about using multiple PTT applications on one device and most of them work fine but sometimes you wish you just have it all in one application. This was the starting point from were NR001, ZRB003 , NR0216 and me NR515 at www.zelloradiobenelux.be started testing.

Reboot in Safe mode

When having problems with a device and you want to boot up without any apps starting.

Reboot to safe mode

Long press your power button until the shut down menu appears
On the popup where you can power off or reboot you can long press ‘power off’. It will ask to boot in safe mode. When you do this the device will boot normally but won’t auto start any apps.
Keep in mind: Not all devices have this feature. The manufacturer decides.

Channel Knob Selection

Another great tip by @Phil NR001
(Only applicable for devices with a indefinite rotating channel knob selector who run a PRO version of Button Mapper & Google Play Store)

This configuration enables you to use an indefinite channel knob to browse trough your numbered channels.
For me this is a great added feature because now I can safely browse channels when I’m driving in my car. Most of my frequently used channels are assigned to the program buttons, but now you have a more extended channel list at your finger tips.

Example on an Inrico TM-7 plus
  1. Add numbering to your channels/contacts: 01 Channel 01, 02 Channel 02, 03 Mom, …
  2. Add the rotate left & rotate right button in Button Mapper
    1. (“Add Buttons” or sometimes they are already added)
  3. For the Left Button: Select “Broadcast Intent” and add the following line to the field “Action“: com.zello.intent.channelDown
    • Do this for “Single”, “Double” and “Long Press”
  4. For the Right Button: Select “Broadcast Intent” and add the following line to the field “Action“: com.zello.intent.channelUp
    • Do this for “Single”, “Double” and “Long Press” and mind the capitals!

This should work with most indefinite rotating channel knob selectors. If you find a Network radio that doesn’t support this, let us know!
(We know about the Telo TE-390 already)

Multiple PTT apps on your Device

Some of use more than one PTT app on their Network radio.
Me, for example, I use Zello for hobby and when at work I use WalkieFleet to communicate with my team. I don’t like to carry around to many devices
(I do like to collect them though 😁 ).
Other hobbyists like to use peanut, echolink, …

Zello, in its greatness, has a few items that might need some improvement or modification, but I’ll leave that to the project managers and developers. I’ll just stick to solutions and work arounds.

When you install Zello it claims all usage over the PTT button. No matter what you do, when you push the PTT button it will push Zello as primary PTT application and it will pop up. (Unless you disabled background usage in the PPT menu in Zello, but that’s only when your screen is off.)

This is actually great when you only use Zello, but like me if you use other apps like WalkieFleet it’s quite annoying. There’s are two ways to work around this:

Sound Enhancement

In a random chat on one of our favorite channels, we were talking about PD0KHN, Martin’s newest addition to his Radio Park: an Inrico T320. We were discussing that adjusting the sound is not a subtile matter, it goes with button clicks and it’s lowest volume is sometimes just a little bit too loud. Same goes for the TM-7 (plus)… we all experienced the same issue. We got interrupted by Jeerke77 who told us that if you disable the Sound Enhancement in Android Sound Settings, the volume is far more softer and subtile in its lower volumes.

TM-7 (Plus) WiFi issues

Had some issues lately with my TM-7 plus who disconnected often from my wifi network. It happens on irregular basis and sometimes during conversations, what makes it very irritating obviously. I thought the problem was located in my mesh network, that the network was too advanced for the Android 4.4 versionof my TM-7 plus. We discussed it on the Zello Radio Benelux Channel and apparently it’s a know issue for the TM-7 (Plus). I got the suggestion to install “Best Wifi Keeper” That seems to resolve that issue.
