Rats - I was hoping there was some magic going on with that radio and supporting SFR. Thank you all for your expenses and relaying your efforts with this.
Update: So I went back to the drawing board and set up the 578 as a single frequency DMR repeater. Again, I got it to work around the house but still getting intermittent digital audio drops every once in a while. So it worked (kinda) but then again when I went beyond 1/2 mile the system doesn't transmit correctly (no range). I would agree with the other commentors here regarding desense on seperate frequencies but theoretically it should work in digital on the same frequency. Theses are packets that are being received on Time slot 1 and then rebroadcast (on the same frequency) on time slot 2. This is a digital carrier transmission similar to a TDMA (which the ETSI standard is) so it should work but doesn't. I reached out to Bridgecom Systems and have been waiting all week for a reply to this problem. They told me that even though Anytone says they have a "cross-band repeater mode" that it doesn't work because there is no internal duplexer and you actually need a real repeater. "Its just a radio", they said. They went on to say that it definitely is not designed to do VHF to VHF, or UHF to UHF cross-banding. I wish I would have known all this because I spent a good solid 2-3 weeks of trying to make it work. So I guess repeater here I come. Had a nice conversation regarding Hytera digital repeaters so I might go in that direction. Thanks everyone...
PSHi all,
I bought a AT578 last week and played with quite a lot.
- I tried SFR mode and was quite disappointed too...
it's seems to be working (TS1 -> TS2) but it's a very poor quality with glitch, blank and sometimes it's close to be good...
My reference is Hytera used as SFR where the quality is really correct is not great !
I know that this is not the same price but selling a device with feature that is not really working is a kind of lie.
- I'm also using it with an Open Spot and it's ok (after offset setting).
- On FM UHF I have a good reception maybe some ghost signal (paging / beacon). Good audio report as well.
- On DMR reception (professional) it's not always decoding even with Digi Mode active.
If anyone want to share SFR experience, more that welcome (for me this one the key feature).

@gman1971 , You are correct over the past couple of days, when running the frequencies or memories scan with Digi Mon activated,
I also noticed that the radio freezes...
I wasn't sure if it was linked to the USB port always connected to my PC so I disconnected it but no improvement.
These bugs are really annoying and unacceptable.
The more I test it, the less I like it....
My primary reason for holding off on a purchase is the lack of "split mount" design, but the bug infestation supports my resolve to not even consider it for a base use.After reading all the reviews, it looks like I will wait until I buy a 578. Thanks you for the great reviews.
I had the radio in my cart and was ready to buy it. Then I thought I better check the forums and I am glad I did. Lets hope they fix the issues soon.My primary reason for holding off on a purchase is the lack of "split mount" design, but the bug infestation supports my resolve to not even consider it for a base use.
I just ordered an AnyTone AT-D578UV III so we'll see how this goes. The last thing I need in my life is another radio.
BTW, you can get it for $389 from "letsgetready" on fleabay with free shipping and 1yr US warranty.

Thanks for the update. I got the radio a few days ago but haven't had the chance to install it, and I hope it already has the new firmware.Hi all,
1 mounth after the acquisition, thing are doing better...
I did a firmware upgrade to 1.07 and 1.07R, thx to Anytone team who has been reactive to suggest and share this. Not all the manufacturers are answering to users...
- First I tried again to use the SFR mode with a pocket Hytera which has a proper tier II and all went much better ! The sound is close to be perfect and it's working fine. Good news !
- Once again this is critical to optimize the offset on the frequency that you will use for HotSpot.
- DMR scan is ok.
- I noticed that when listening a DRM traffic with encryption or some NXDN traffic the Anytone got frozen... I have been able te reproduce this on 2 specific frequencies with such transmission. the only solution is to turn off the power supply.
Take a moment to bench power the radio to see what firmware it has. Not uncommon for hardware to lag user installable firmware.Thanks for the update. I got the radio a few days ago but haven't had the chance to install it, and I hope it already has the new firmware.
I am walking out to program the radio since I just finished the new code plug. I will let you know what firmware it has. Thanks for the recommendation of bench testing it first.Take a moment to bench power the radio to see what firmware it has. Not uncommon for hardware to lag user installable firmware.
