XPR7550e receiving interruption with Hytera repeater

[bx2aek]

Dear Motorola xpr7550 users: I recently had a 7550e for DMR communication and for some reason it works well with the MMDVM and Openspot either with wifi or cable modem. However, when it receives from my Hytera RD980 repeater, the QSO often being interrupted intermittently sometimes even most of the QSOare gone. I have experimented with my other Anytone radios that there is no issue with my ADSL network connected with the repeater.

Would like to seek input from ther group as how to troubleshoot this issue. The 7550e seems not working consistently with the Hytera repeater but much stabler with the hotspot devices.

BTW the Hytera model is RD980(EMEA version I believe with Russian language marks), the 7550e was bought in the US. Not sure if there is compatibility challenge..

Thanks and 73s.

My money is either the Hytera or the Motorola are on the edge of specs. Do you have another radio to test the repeater with? TT

Thanks for input. I did try my Anytone 878 parallel with Moto 7550e, it sounds like Moto has mre chance to experience the broken signal while Anytone had much less incidents. I heard Anytone has more buffering to decode the delayed signal but Moto requires accurate timing. I am not sure what can be done to troubleshoot this...

Sounds like the Moto or Hytera needs service (alignment). I would seek a competent dealer for each of those to ask for the radio to be aligned. My bet would be a Moto dealer would be easier to find. TT

I would be looking at the raw signals with an SDR and DSD+.

Is the Hytera repeater hi, or lie split?
