IC-R9000 & digital modes

Hello everybody, recently I got an IC-R9000 and I'm very very happy with it.
Now I would like to add something to decode VHF/UHF digital modes like DMR, D-Star, C4FM, Tetra and so on.
I don't want to use my computer for radio listening, so no USB sticks, software and so on.
I'm interesting only in standalone, hardware-based devices. Something to connect to the 10.7MHz IF out of my R9000.
I know that an AOR decoder was available in the past, but it did not decode Tetra and it seems discontinued. And, last but not least, recently I had a bad experience with AOR (got a VERY EXPENSIVE AR5700D, sold after just two months, absolutely disappointing in my opinion).
Anyone could suggest a good solution? Thanks.

Hmmmm AOR..... again???? Never tested the DV1, but as mentioned above the flagship AR5700D was a big big disappointment for me.
However, in your suggested configuration I believe that the DV1 input must stay locked at 10.7MHz, right?
I did not know that it can decode digital modes in "HF bands" too.
So, if I understand correctly, the DV1 would become a simple "decoder", and all tuning operations would be performed by the R9000.
If it works, I think it could be a good solution.
Is the DV1 able to decode all digital modes automatically including Tetra?
I do not believe that the IF out of the R9000 provides any voltage. It surely occurred with the R8500 that I owned in the past because that output jack was used to supply the TV module, but don't think in the R9000. Please correct me if I wrong.
Thank you for your suggestion. Waiting for more possible options, if any.

The only standalone, hardware based digital decoder that I am aware of is from your old friends at AOR.
The AOR ARD300:
Maybe some others know of some other solutions.

You may want to look at using some software packages like DSD+ or SDR# to decode digital modes with the discriminator output.
I have used these packages with an R8600 to decode DMR and other unsupported modes.
Good luck!
