Decoding telnet and aprsc-status data

NOTE: This page describes the debug output via telnet.
For the APRS stream, see subscribe-to-ogn-data!

Hopefully this page will explain to some degree what we see on telnet and the servers.


This section shows some example output via telnet.


APRS_Sender.Exec() … Beacon:
UK-BNN>APRS,qAR:/210543h5117.27NI00105.48W&/A=000308 CPU:3.8 RAM:37.9/192.6MB NTP:5.0ms/-41.4ppm +41.2C RF:+60+0.0ppm/+1.7dB

=> your receiver sends a beacon message with some information.

APRS server: # aprsc 2.0.14-g28c5a6a 11 May 2014 21:05:42 GMT GLIDERN2
=> APRS server sends to your receiver a keep alive/beacon message

APRS server: UK-WOG>APRS,TCPIP*,qAC,GLIDERN2:/210632h5152.87NI00113.75W&/A=000495 CPU:0.7 RAM:316.0/492.2MB NTP:0.4ms/-43.7ppm +49.2C RF:+32-1.8ppm/+2.5dB
=> APRS server sends you a beacon message from receivers close to yours

ProcessTimeSlot(badCRC/4.8dB/-3.0kHz) => no track => badCRC
=>A debug message, to trace how the logic of linking signals with tracks works. This particular message means: there was a signal (SNR/freq.offset), no track could be assigned to it, could not be made for correct CRC by error correction.
