[Elecraft] SDR_Sound_Cards

[Olli Tuppurainen]

I have pretty much given up  my LP-PAN +CW skimmer and NAP3 ever since I
upgraded my PC OS from XP to WIN7 ( 64bit ) with AMD X4 Phenom.

Tried now two different soundcards Infrasonic Quartet ( did work OK in XP )
and now recently bought EMU 0204 and same " nightmare " continues. Have
taken memory physically out from PC and limited use of memory in down to 3G,
did run things with " admin " rights and XP SP3  compatibilty  but nothing
seems to to work.

stick with XP 32bit if you want to use these.. :(
