gMFSK & QSSTV

gMFSK & QSSTV

[Eric W. Davenport]

I too have a box with 2 sound cards and a TV Card in it. 
The Radio connections are through the SoundBlaster Audigy (dev/dsp1 ) 
mounted in a PCI Slot the computer speakers are on the MB Sound Card.
Radio In is to Line IN and Radio OUT is through the Headphone 
connection.  I am using a rigblaster to interface.

Once I figured out which one was the SB Audigy gMFSK works great in all 
modes. I have not changed any of the default conditions.  All I did was 
set up the audio card to the proper unit bring up the mixer make sure 
that I was changing the SB Card and everything started working.


I am however having trouble with QSSTV.  I cannot get a picture. (Ver 
5.03c) I am getting video but it is distorted looks like it lying down.  
Slant will not help.  I have been playing with my sampling rates and 
nothing helps I have been up at 11000 where MixW was and as low as 7000 
nothing seems to change it.

I saw the script that Al uses and would like to try it but.. I have 
never created a script so I do not know where to use it.  User a 
terminal program and run it from there then launch QSSTV, does not seem 
like it will work since it requires SU.  If I am in SU then if I launch 
QSSTV it will not find the config file.

So I am confused and if anybody can help me I would appreciate it.

You can run the script as SU, then run qsstv as a regular user.  I run the
script from rc.local during boot.  It only has to be run once per boot.
If you want to add another ap to the list, you can run it again as root.

Well I implemented Al's Script.  Here is what I noticed.  In gMFSK my 
levels were way down from the night before.  I had to crank in more 
volume than I had to have the night before.  This could have been 
conditions but I do not think so.

I qSSTV I still get garbage video.  I get video but the picture looks to 
be skewed diagonally does anyone have 5.03c running and getting 
pictures.  If so what frequency are you using? Is there a way to use WWV 
to set the proper frequency as there is in MixW?  How else can I get 
this to work.  The computer is a dual boot and on the Windows side MixW 
SSTV works fine with the same card.

Any help is appreciated.
