I don't think you can receive I-calls but yes you can recieve both trunked and conventional at the same time you can even program them in the same bank if you want to
DON - An I-CALL is when one radio can make a private call to another radio in a GE EDACS system. I have an old version of the PRO 94 that will not monitor an I-CALL, however I know that there is a scanner that will.
