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.
Our good friend and Zello Radio Benelux user Martin – PD0KHN has engineered a small 12V battery station for his Inrico TM-7. He uses it to take with him around the house and when he goes camping. Very easy to use and recharge! Genius!
Our good friend and ROM GURU, NR001 – Phil, has released the latest firmwares updates of his debloated ROMS. See below for the list!

The Inrico TM-7 plus has a lot of advantages and for me it’s probably one of the best mobile devices out there for the moment. But is has one big issue and that is the total useless volume knob. If you dial the knob to change the volume, it just starts a life on its own. The volume flies to on end of the spectrum to the other… really awful and even dangerous in the car.
Luckily there is a work around for it.
The first solution is just uninstall Button Mapper, because this is causing the issue.
The second solution is by configuring the navigation buttons (Up & Down) as volume buttons via Button Mapper. (Oh the irony!)
In Button Mapper, go to option “+ add more buttons”
Press the “up key” on the right next to your display and confirm that you want to add it.
Then select customise.
The 3 button actions become active (single, double & long press)
Assign to all 3 buttons actions the same Action: “Volume +”
Do the same for for the “Down Key” with the Action: “Volume –“
and you’re good to go…
Now you can adjust the volume settings with the up and down key.
Today we finally implemented the TM-7 plus in the interior roof console of my pick-up truck. There were a few things that I was worried about:
First thing was if the roofconsole fitted the interior of my car, that sorted itself out after a quick fit. Next to that I was happy to see that the format of the TM-7 plus is DIN standard and just slides in the radio compartment as if it was made for it. That was already one thing less to worry about.
Also I was a bit worried for letting my car in the city with the Radio in plain sight. The radio is firmly fixed in the slide but can easily pulled out. We connected a special connector in the wiring that I could disconnect with 1 click en take it all out. Also I can use this to do updates or maintenance behind my computer
The last thing I worried about was something we discussed on the Zello Radio Benelux Channel, and that was how to wire the radio: before or after the ignition. Before meant that it would be always on because the TM-7 plus has no power of button (it just reboots.) Behind the ignition contact would mean that every time you turn the contact of it has to boot when you turn the ignition key on again and the TM-7 plus takes a while to boot! This is no problem if your trips last 900 miles and you don’t plan to stop for the first 450 miles. But if you’re going for groceries, it’s a whole different story!
Luckily our good friend Martin – PD0KHN, member on Zello Radio Benelux, came up with a logical solution. He suggested to wire the radio directly to the car battery and put a switch in between. The radio use will not be interfered by the state of the ignition being “on” or “of”. I discussed that idea with NR001 and some other folks on ZRB and we all agreed that this was the best solution. This is how we implemented it:
We all know that the TM-7 plus and ButtonMapper don’t have a perfect marriage. Being able to adjust the volume in the car in a safe way is very important. You can optimise the volume functionality in two ways:
1. Uninstall ButtonMapper: Then your volume knob will work just fine. But you loose the ability to quickly change channels and contacts with your Program Buttons (see How to map speed dials to channels and contacts in Button mapper.)
2. You can map the up and down arrows to volume up and down in ButtonMapper. Important is that you map all three options (single, double & long press) to the specific function of that button. (If some one needs help with that let me know, I’ll write a short tutorial.)
Anyway. Happy me! It feels a lot better handeling this mic in the car. The speaker is next to my head so the volume doesn’t have to be loud. I don’t have to take all gear in and out every time I leave at home (I have aT320 in the bag but that is switched on when necessary when i’m out of the car.)
If you have any questions or improvements feel free to share in the comments.
Tip by Phil – NROO1
On mobile devices you can map the P1/2/3/4 buttons to go to a channel/contact in Zello with Button Mapper. In theory you can map any hardware button to a channel or contact except for buttons that are preoccupied by the Zello app: SOS-button, PPT , … If you still use your dialer, make sure you map the long press key and not the single press key.
- Rename the channels you want to add to 01, 02 and so on …
- Add the buttons in Button Mapper and for every button add the Action: “Broadcast Intent” to single tap (for CH 05 to 08 use long press)
- In the field “action” add “com.dfl.knob” (without the brackets)
- in the field “key:value” add “frequencyNum:XX” where XX is the number of the channel(01, 02…)
- save and try
- Warning: This only works in the donation version!!!
This also works with other numbers, so if you have allready setup different numbering on your account you can also map “03 ZRB to P2” or “16 Mom to P4”
If you want to use the “single press” on the P1, you should config the “long press” on P1 identical to the “short press.” Otherwise it will not work with “short press” We don’t know why but that’s the work around we found 😉
