DSDPlus Choppy audio on P25 systems

[VA3ADP]

For the last several months, I've been experiencing choppy audio and audio that is constantly cutting in and out on 700/800mhz P25 systems. Are there any recommendations to improve this?

Thank you

That has something to do with signal quality. Move your antenna around until all LCN's sound better. Don't be surprised if the antennas best signal spot might be in a spot like the kitchen sink or some other places in your home you wouldn't want an antenna. RF is funny like that.

You don't say if it once was very good and has deteriorated or if you are new to this system or DSDPlus and it just doesn't seem good.
Computer specs can make a big difference. In my experience, Intel chips out perform AMD by a wide margin for DSDPlus. Also adequate memory so the system isn't running at %100 memory usage.

Il have to play with the windows graphic settings and see what chip DSDPlus is running.

It is not the graphics, it is the computer CPU that I am talking about. If you go to Start, Control Panel, System... it should be shown there

I am running an Intel CPU with NVIDIA Graphics.

look in the black window that shows the streaming data and see if you have constant errors.

You can post a screen shot with the FMPx window and the one I mentioned shown

Was said system once much clearer? If yes & there haven't been any changes on your end then perhaps a site went down or maybe there's a new source of RFI in your area, cell tower, etc. Could be anything

I'll give it a try tonight or tomorrow and post a screenshot

here is a screenshot of the FMPx window. Seems to be quite a few errors indeed. I am beginning to think it is some RFI causing this

aqui está uma captura de tela da janela do FMPx. Parece haver alguns erros de fato. Estou começando a pensar que há alguma RFI causando isso

What is your dongle? The SDR v3/v4 its wrong for this, i buy the "SSDR Liga de Alumínio Módulo Receptor, Simplificado Software Definido Rádio, 12Bit, 10K-1Ghz Largura de Banda, RSP1", the bits for dongles v3/v4 not allowed to receive all information because its 8 bits
