[amsat-bb] IC9100 Data socket 2

When I try to operate "SPLIT" the PTT from data socket 2 is disabled! I can short the pins and no transmit. Not in split works fine. Also works fine in ACC. Need the split for data with ISS and the APRS birds. Have I missed something in the manual, is my radio broke or did ICOM have a senior moment? Tom K8TL k8tl@earthlink.net
