Sorry, something was going wrong with the radio buttons for the audio routing. Here is a corrected version:http://dl2rum.de/rumsoft/RUMpedBeta.zip
Or you can use Chen's great software to configure the MKII.
Once again, what do you want to do with the MKII? What are your connections between the MKII and the radio?
I set the option to use the MK2 for voice.
For voice you have to set the audio routing and the PTT options correct and RUMped must set to SSB. This will switch the MKII into the Voice mode. Do you have a mic connected or do you want to transmit the sound card output?
It may be hard job to configure the MKII for your needs. The MKII use a specific protocol to communicate with the computer. Only the sound card is direct accessible, for all other "sub devices" (CAT, FSK, WinKeyer...) you need a special software. Further, the MKII must be switched into the correct operating mode. You can not use it as stand alone device.
