How do I set the transmit and receive analog levels on the sound card to use it as a sound modem or is it possible? I'm using a sound blaster sound card it says 'SB 4.05 detected OK' in dmsg. I compiled sound modem support into the kernel (I think) and I'm using soundmodemconfig to set it up. I can copy the traffic on my radio through the sound card OK, although I have the output from the radio going into the 'mic' input on the sound card instead of the line input. I've even got the PTT working (with some help from people on this list, thanks). Now when I try to transmit the radio is keyed but I don't think I'm transmitting anything and I got thinking, how can I adjust the transmit, or for that mater, the receive analog levels??? Have I missed something really basic, or am I just not understanding the way it works? -- No virus found in this outgoing message. Checked by AVG Anti-Virus.
