Hi all,

Again i spent some time to find a module which allows to transfer a 
mircophone input signal via WLAN to the PC. Without success...

To make things clear:

The system has to consist of to parts:

1: The first one is battery supplied and has a microphone input (like a 
cheap external USB soundcard) and a WLAN output, using an external 
antenna and SMA plug. I.e.: Input: 3.5mm microphone jack. Output: SMA 
WLAN antenna connector.
2: The second part is connected to the PC and is a WLAN receiver that 
appears as a normal external USB soundcard and allows to receive the 
audio signal from the first part of the system.

The system allows to run a /p receiver for VLF or any other band.


An expert could create such a circuit for himselfe but i need to buy 
something like that, if it is available. But all i can find in the web 
is the opposite way, i.e. people who want to transfer their sound from 
the PC to a /p loudspeaker or headphone, argh...  Or, a big device which 
includes a real big microphone (dynamic range ???). These are expensive 
systems.

However, external soundcards are cheap and WLAN modules are cheap too.

So, isn't there such a device for a few EUR in the web, these days? It 
has to have a dynamic range of  at least 100 dB, like the 2 EUR external 
soundcards at amazon do (with some luck).

Any help is much apprechiated :-)
