I want to use my soundcard as a modem.I heard ham radio operators do this and installed soundmodem on my damn small linux laptop.I don't have a ham liscence just a radio scanner that has 2m 6m and 10m ham radio bands.I know I have heard them before but now that I want to find them I can't.

Does anyone knows how I can find these transmission frequencies in my area without many hours of scanning?

I only want to find them to test out soundmodem.I want to know what I can use it to decode.

For example ,If I was to dial in to my isp on speakerphone,could my laptop communicate with it through the sound card?

It's just sort of an experiment.

First thought was no way but a quick search on google pointed me to this link. Should be a start and a name of program to research. http://linux.maruhn.com/sec/multimon.html

What is your area?

If I understand your question packet radio does not work like that. You connect the audio output of the scanner to the input of the soundcard. The soundcard decodes the packet radio signal and when you select monitor mode you will see conversations on the laptop. Since you do not have a license all you can do is listen.

I was hoping for a link to a listing of radio base stations by area .The packet radio stuff is interesting but I would rather find a way to use my sound card as an acoustically coupled modem.If there was some way to redirect the microphone input to the modem recieve buffer??Of course it wouldn't be as fast as a regular modem.Maybe find ways to decode other types of data with it too,later.

Hi,

The soundcard is used to demodulate audio signals coming over the radio. The radio audio output is fed into the input of the soundcard and the digitally modulated audio is decoded to readable text, which appears on the computer screen. A soundcard is not set up to connect to a distant modem over the telephone line like a serial modem is: two different things.

Hope to hear you on the air someday!

Thanks guys I've got plenty of info to keep me busy for a while.Also a few problems need fixing.Thanks ny6p ,it looks like you registered just to help.Welcome to LQ hope you keep coming back.I still think I can do it but not with this software. Maybe it won't be very useful but who knows?
