The biggest difference it the dual-receive function. With the 8800, you can listen to two frequencies (e.g. 146.55 and 443.65mHz) at the same time. On the other hand, if I'm not mistaken, the 7800 only allows you to listen to one freq at any given time. I haven't used a single-receive radio like the 7800, but I do think the dual-receive of the 8000-series radios is very convenient. Sometimes I have my 8900 set to receive 146.55 and 162.xx (weather radio) concurrently, and other times I have it set to receive a Skywarn station + some other freq. Regardless, I don't think I'll ever buy a single-receive mobile given the convenience of a dual-receive.
