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).

Muting Matrix

Here you see a matrix documenting the behavior of the blocking-lists and configuration of regular expression (RE)-check:

Within this table following descriptions for the cell-values should help understanding the table:

X: Any value
YES: set and matches with callsign/gateway/ip-address
NO: not set
1: check via RE enabled, normal operation
0: check via RE disabled, but passes everything
-1: check via RE disabled, but only pass whitelist

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:

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

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.
