I've got the 8800, I like it a lot. Here's all the stuff I can say that's bad with it:
-the buttons aren't backlit like on the 7800. Also the faceplate buttons are really small, you think you're hitting the memory one but dangit now you're scanning again..
-the dang thing has way too many features, I still haven't learned most of them. After trying to get a repeater to work, I had the "wires" mode on for most of Cruise Moab and the whole way back, so I was transmitting with a 'beep' every time. Pretty frustrating, and I couldn't find that in the book anywhere. but then an old guy on a local repeater told me what button to push and boy did I feel stupid, and relieved. So now I don't beep, but I expect a few more of those episodes.. however that's likely more about me being a newb than the 8800. If you get one I'll tell you the magic button to press.
-We had an interesting discussion about the legality of the cross-band repeat mode in our member's only forum a while back.. suffice it to say how you think you may use the cross-band repeat mode may not be entirely FCC-compliant, particularly when dealing with the proximity of the station and its control operator. Don't let that dissuade you though, but DaveinDenver brought up some good points that made me second-guess how I was thinking of using this feature some day.
do you want Pros?
- true dual band mode flat out rules. Have the radio on two channels, you just tap the button of the channel you want to transmit on. Awesome for monitoring a repeater to pick up folks far away, while staying in touch with the local group running on simplex. Independent volume and squelch knobs for each channel... man it's cool.
-Lots of other stuff too, but dual band is still my stand out favorite. the 7800 is an awesome radio, the 8800 really should be all that and then some. I just wish the buttons were lit. hth...
