   Hi Peter,

   Thanks for your future contribution. It is for the good for future
   LINRAD users and to get more people on board.
    
   I do not want to throw you of the track so the say, but 
   there are a few other reflectors that cover DSP etc.
   You might look at the the dsp-10@xxxxxxx  I am sure 
   you will get response there. Go to www.qth.net or
   www.qsl.net and look for users groups. You will
   find there all sorts of facets of amateur radio covered and
   also the dsp10  and I believe dsp group. Then there are the 
   TAPR people 
 
    www.tapr.org
     
    they are into those LO's, GPS stuff etc. If you monitor
    what tis going on there, you will find info that will help you
     
    They tell me that those DELTA44 boards are on eBAy,
    ( go to the  US section ) In Holland there is not much 
   going on eBay yet. The prices are better but it can be
   frustrating to become the winner.
   I would think that you would not have any problems
   getting it through customs. You can find these cards
   in high end audio equipment stores, audio amplifiers,
   mixers, etc I am sure if you go in there, they might
   be able to help you. It is not something, you are
   going to find in computer stores. It is a specialized
   device. There is a link on the data collection to the 
   company and the providers for the software you will
   need to make it part of Linrad.

   Good luck during the weekend,
