Good Morning All,

Still trying to get the 7800 wired up right to the pc to get DX Lab working. What I am using from the 7800 to the pc is a db9 straight through cable. In the 7800 manual it says the rs232 jack is wired as a modem (dce). Should the stright through cable work or do I need a null modem cable? Thanks,

Steve, WD8NPL

I am running an Icom 7800 which I had hooked up to DX Lab until about a year ago when we moved. I cannot remember for the life of me how I had it hooked up but am thinking a ran an RS-232 cable from the rig to the pc. I cannot get it to run now and am thinking perhaps I do not have the right cable. Can someone please advise this OM?

+ You must connect a COM port on your computer to an Icom CI-V interface, which is in turn connected to the Remote jack on the backpanel of your IC-7800. You can build or buy the CI-V interface; see
