.SH NAME
|
|
atest \- Decode AX.25 frames from an audio file.
|

.SH DESCRIPTION
|
|
\fBatest\fR is a test application which decodes AX.25 frames from an audio recording. This provides an easy way to test Dire Wolf decoding performance much quicker than normal real-time.
|
|
|
|
|
|
|
|
.SH OPTIONS
|
|
|
|
.TP
|
|
.BI "-B " "n"
|
|
Bits / second for data. Proper modem selected for 300, 1200, 9600.
|
|
300 baud uses 1600/1800 Hz AFSK.
|
|
1200 (default) baud uses 1200/2200 Hz AFSK.
|
|
9600 baud uses K9NG/G2RUH standard.
|
|
|
|
.TP
|
|
.BI "-D " "n"
|
|
Divide audio sample rate by n.
|
|
|
|
.TP
|
|
.BI "-F " "n"
|
|
Amount of effort to try fixing frames with an invalid CRC.
|
|
0 (default) = consider only correct frames.
|
|
1 = Try to fix only a single bit.
|
|
more = Try modifying more bits to get a good CRC.
|
|
|
|
.TP
|
|
.BI "-P " "m"
|
|
Select the demodulator type such as A, B, C, D (default for 300 baud), E (default for 1200 baud), F, A+, B+, C+, D+, E+, F+.
