Hello,

I have upgraded the ATS25 Max Decoder II firmware to ver4.2 AIR. How do I enable the new HAM bands 6M, 2M, VHF and AIR ?

Hello everyone,

I recently purchased the ATS25 Max Decover V2 so that I could listen to air traffic radio, among other things. Unfortunately, the Air feature is grayed out. Does anyone know what the problem might be?

Firmware version 4.21 is installed, and if I'm not mistaken, the software is also activated.

Perhaps someone has a tip for me.

Please provide a photo of the inside of your receiver, it is likely that your receiver does not have AIR BAND hardware support.

Okay, is there a separate component that is required to use the Air function?

Hi
I too have the same radio, purchased solely to listen to 2m/6m and Air craft traffic.
What do you need from me to activate?
73's

This model receiver don't have schematic for air & 2m bands

Then why did you ask Percolate5164 for a picture of his radio?
If mine is the same model.

Thanks
