pYSFReflector

This is a YSF Reflector implemented in python3, mainly compatible with g4klx reflector.

Additional Features

Enhanced Blocking List

With the enhanced blocking list you are able to mute calls based on

• callsign of sender
• callsign of gateway used
• ip-address of gateway

Blocking On Regular Expression Callsign Check

It is also possible to use (by default enabled in the YSFReflector.ini) a callsign check based on a regular expression to check the callsign plausibility in callsign-format and length.

The result of this check can be overdriven by a whitelist-entry in the blocklist (for example: N0CALL is blocked by default by this expression but could be allowed for special bridging situations).

Avoiding Parallel Incomming Transmissions

There is also a functionality implemented that prohibits parallel transmissions that can happen if two senders transmit at the same time. Here the principle 'first-comes-first-serves' is realized, so the second station in time will just be muted to not disturb the audio.

Easy Installation And Upgrade

Depending on your used operating system and python3-installation you just have to take care that following libraries are installed:

• socket
• threading
• queue
• sys
• os
• time
• re
• configparser
• datetime
• signal
• datetime
• bisect
• struct

In most installations this packages are already installed, otherwise you easily can install them with your system-package-manager (for example Debian: apt) or you use pip3 install -command.

The configuration file (YSFReflector.ini) is based on the origin YSFReflector.ini of G4KLX's YSFReflector but with added new configuration-items. So If you know the old reflector-software - configuring this one would be straight forward.
