Add Support for RTL2832 With R828D Tuner (aka rtl-sdr V4 dongle)

[alphafox02]

Ubuntu 22.04
Latest SDRTrunk Release

I'm testing various applications with the RTLSDR v4, and I noticed now with SDRTrunk it will not start w/ an error indicating Unsupported/Unrecognized Tuner Type. I have the latest Osmocom RTLSDR source compiled and installed w/ V4 support.

I suspect something in here needs to be updated to account for the V4 changes?

Happy to test anything since I have the V4 handy.

The RTLSDR V4 is recognized as the "Rafael Micro R828D tuner"

First off, thank you for your efforts on this product. I have been a user for many years. Unfortunately the rtl-sdr dongles I get keep changing. I’ve purchased five new ones to try a Phase II system upload for Radio Reference and have not been able to get the tuners recognized. Would it be possible to include some of the newer inexpensive tuners on a future release. Specifically I’ve tried the aforementioned “Rafael Micro R828D” as well as the Fitpower “FC0012”, neither appear to be supported for SDRTrunk. I really like your product. Just having difficulty locating newer supported inexpensive dongles. Thx. Patrick

Denny- I would also be willing to help test support for any of these tuners. Thx. Patrick.

It would be wonderful if the software could be updated to include some of the less costly applications. I see the software looks like it wanted to include V4 and Fitpower but it does not recognize them. I don’t know enough about programming to try to change the tuner name but as mentioned but my V4 is a “Rafael Micro R828D” with a space —- I think the program is looking for “RafaelMicro R828D” with no space. In any event, the V3 is harder to find and I can’t really invest in the $200 versions. I had been using an inexpensive V3 from China (blue USB) and it works great. I need several more to run a P25 system can’t really invest in the $200 top of the line versions.

Suggestion, although it may be faster to just add in the v4 supper to your code, but what about building a way for sdrtrunk to accept rtl_tcp input? Even if the user ran rtl_tcp on the same machine as sdrtrunk it would at least (I think?) push the usage of the rtlsdr dongle onto rtl_tcp itself and in turn would use the native driver from osmocom that’s been patched for the v4.

Could also be a good way to have an rtlsdr located away from the sdrtrunk PC. Just a thought.

I too am using the V4 (along with other tuners) and would really like to see this support added. I agree that if you could lean on something like rtlsdr.dll this might make it more future-proof but I can see there might be more work in that. Ongoing maintenance and support of this excellent app is really appreciated! Thanks

I am using V4 also, purchased 5 of them not realising they weren't supported. My bad.

I have a v4 batch 2 on the way.

Awesome! I fired up op25 yesterday and it did well with p25 phase 2 on 700ish MHz so I’m sure it’ll work great in sdrtrunk.

How does OP25 do with simulcast P25 Phase 2?

Do you plan to add Bias T control or let it ride with the eeprom option?

[grahampaull]

I have a v4 batch 2 on the way.

Brilliant.

[Cagier]

Thanks so much for adding this (and all the other work you do in this great project)

[grahampaull]

Brilliant. Will give this a go. Thank you.

[alphafox02]

That was quick! Thank you very much for adding the support. I’ll update things in my OS asap.
