A common point of confusion for digital voice users is the difference between Bit Error Rate (BER) and Packet Loss (Loss). Because both issues can cause choppy, robotic, or dropped audio, they are often mistaken for the same thing.

However, they are completely different measurements that occur on entirely different parts of your hotspot setup.

When you use your WPSD hotspot to connect to a YSF reflector, a DCS room, a DMR network, or a P25 talkgroup, you are picking from a list. That list – the names, IDs, addresses, and ports your hotspot uses to make those connections – comes from hostfiles.

Recently, we made a change to WPSD to help better educate users, and to make WPSD operate better with the various modems out there. However, users have been conditioned by poor documentation to select the incorrect modem type.

If you have been prompted to re-select your modem, or you are trying to find the “STM32-DVM / MMDVM_HS” modem in the Configuration Page, you’ll want to read this document.

We frequently see user help questions starting with “it doesn’t work”, and no other details. We can’t help without more information. This document is intended to inform you how to ask for help in a way that the WPSD community can effectively help you.
