setting an IC7200 and 7300 up for split operation.
The first step is to download the entire manual and read it cover to cover which will confuse you and leave you addled. Next forget everything you read and sit in front of your rig and turn it on. Always remember that a radio works best when it is plugged in. Go to the band of the station running split. Look for the A/B button and the split button so you know where they are. Now look at the screen for VFO A. If it says VFO B then push the A/B button quickly and you should be on VFO A. Set VFO A to the frequency you want to listen to. Next push/A/B again. You should be on VFO B. Set it to the frequency you want to transmit on. Push A/B again so you are now on VFO A. Push the SPLIT button and you're good to go. Other rigs may have somewhat different settings buy you should get the general idea.
