Re: [linrad] audio channels
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,
