OpenEar will be new software for listening to Voice and data of protocols(Tetra, DMR, MPT,...)

Will you support Airspy R2 ?

currently only RTL-USB supported, but i try to add multi-hardware support on near future

Looks very cool. Any chance of a Linux port?

Hi there!
Just tried 1.6.0 and wanted to give my input.
TETRA works fine for me, don't have to off center anything, always click on the center of signal and it starts decoding voice just fine.
However it's sometimes hard clicking on the exact center, two pixels off and it won't decode - really need an AFC function here as the spectrum/waterfall is fixed at 1MHz bandwidth, at least 2MHz and 0.5MHz option would be nice to have in addition.
Also gain adjustment for LNA gain and VGA gain would be really useful (and Mixer gain too if possible).
A selected frequency display is a must, it doesn't show which frequency it's centered on.
(oh I just noticed there's a (too) small text next to the cursor in the spectrum, but not the waterfall)
Changing the frequency with the scroll wheel by hovering over the digit you want to change is also a must.

Also, the x64 doesn't start on Win 7 x64 (but the x86 version does). Get an "The application was unable to start correctly (0xc000007b)" error.

Otherwise I want to thank you for your time and effort, it's much appreciated - I'm sure it'll be a really nice piece of software if you keep adding protocols and features.
Cheers!
//Greg.

Hi Greg, just a tip with mouse scroll wheel zoom in on the spectrum :)

I really like the fantastic program. Youtube Video in German language

Just a couple of comments
in the UK
Pocsag = 25Khz bandwidth not 12.5Khz which I believe you are using at the moment
I suspect most of Europe is the same
DMR channels are 12.5Khz bandwidth not 25Khz
NFM channels are 12.5Khz bandwidth not 25Khz

You might want to change them on the next version

Also when you click on a memory channel it goes to the centre of the waterfall where the DC Spike is
This is bad as it doesn't receive properly there
Is there a way for you to make the memory channel appear NOT in the centre of the waterfall?

So far the POCSAG working well on my Windows 10 system with NooElec NESDR SMARtee dongles. My suggestion if you really want this to sail off world wide is to add support for ACARS, VDL2 and Flex paging.

Well, I think you saw my post in comments on github.
But, I would like to duplicate it again here:
If you need dPMR trunk traffic - I can get the recorded IQ on sdrsharp, and send it you, may be on e-mail. (Say me YES! :lol: )
It would be great if openear could receive information (such as UID, TGID, system number?) and voice from the dPMR traffic backbone
Now, today I do not know that any software can decode dPMR on Windows. so, many like DSD+, but it not decode voice and data of dPMR. Your project may be the first at this point!
And, If a LOG file is added for network information (UID, TGID and other, maybe in txt format) and an audio recording decoded signal in wav or mp3 then your project will be definitely far ahead :-)

OK I am quite impressed even with the manual scanning type option if you hold down the up and down buttons so an auto scanning option would be great. Atm when you launch it goes back to full screen each time guess that will be fixed ? DMR working well looking forward to future updates, great work !
