I have tackled a new (older) radio for use in communicating with ISS, PCSAT and FM satellites. I am using the Kenwood TM-D700A in the non-TNC mode in conjunction with AGWPE, UISS and UIVIEW software (UIVIEW facilitating my Satgate). I have run a mini-din cable from the Kenwood to a Rascal mixing device then to an external soundcard. There are several reasons I have done this; foremost is the fact that UISS is so user friendly. Also, the signal coming off the minidin is supposed to be much cleaner than running the radio's speakers out (a telemetry requirement for many of the cubesats). This setup works for not only packets but other software types such as WXTOIMG.

My apparent problem is that the signal does not appear to have high enough gain. For instance, when I view the sine wave in AGWPE it is minimal and cannot be adjusted by radio or computer volume. The percent volume indicator in WXTOIMG also lingers on the bottom "edge" at around 41 percent. Perhaps these indicators are irrelative, I am not sure. If someone has used the minidin out for such purposes and could educate me a bit I would be eternally grateful....(well amost HIHI).

And yes, I realize that the radio itself is probably capable is doing many of these things on its own!!
