HF Pager versions history

2.87
The "Carrier detector" was radically redesigned.
A symbol sync was slightly improved
Bugs in the Error Rate calculation were fixed.
2.86t
The test version - carrier detector is disabled.
2.85
The signal quality indicator (Error Rate) is been writing into the text
of the received message.
Baud rate of 46.88 Bd was added. The signal bandwidth in this mode is about one
kilohertz, so use it in those parts of the bands in which wide band digital modes
are allowed. The center frequency of the audio signal at this speed is about
1711 Hz and cannot be changed by the user.
To reduce the load on the processor, you can reduce the number of simultanious
decoding baud rates (Settings / RX Speeds).
2.80
CPU load has been drastically reduced.
Channel busy detection algorithm was improved.
Channel sharing algorithm was improved.

This version will work till 31 January 2021.
V0.96
Bugs in four-hour activity history displaying were fixed.
V0.95
Error Rate (a number of corrected errors in percent) is included at the beginning of object

with fixed comment text.
Status packets from stations with such IDs are not transmitted.
