Just to be sure we all talk about the same thing....
The qsy facility of server version 0.6 does not work on the audio channel,
it qsy's the TRX VFO. So all fldigi config data remain the same, including the
"Low frequency cutoff" and the sweet spot.
To configure a server for scanning the following must be done:
* The server TRX must have a remote control facility. Pskmail uses hamlib,
to be more precise it issues a rigctl command to qsy the TRX.
* Scanning must be enabled in pskmailrc.pl
* The ./qrg/freqs.txt file must be present and have relevant values for
frequency and mode.
* For the qsy facility to work a variable $traffic_qrg = xxxxxxx; must be
present in pskmailrc.pl.
Here is the pskmailrc.pl example running at PI4TUE:
#################################################
# rig control (scheduler, scanner)
$scheduler = 0;
$rigtype = 326;
$rigrate = 9600;
$rigdevice = "/dev/ttyS0";
##########################
$scanner = "F";
$qrgfile = "$ENV{HOME}/qrg/freqs.txt";
$freq_offset = 0; # minutes after '0'
@freq_corrections = qw (-500 -500 -500 -500 -500); # trx frequency correction
@Beaconarray = qw (1 0 0 0 1);
$traffic_qrg = 10146250;
#################################################
The freqs.txt file has:
10147250,10147250,10147250,10147250,10147250
PSK125,PSK250,PSK250,PSK250,PSK250,
Some comments:
PI4TUE uses a IC756, which has a sweet spot of 1500 Hz.
The @freq_corrections array contains the -500 Hz shift from the default 1000 Hz.
PI4TUE uses PSK125 in minute 0, and PSK250 in minutes 1,2,3 and 4.
$rigtype=326 means IC756
$freq_offset=0 is for time shifting all frequencies by a number of minutes
(leave default 0).
@Beaconarray shows beacons to be sent in minutes 0 and 4 after every full hour.
$traffic_qrg is the VFO QSY frequency in Hz (in this case center freq - 1500
Hz).
Hope this helps clarify some things...
