[CQ-Contest] Icom 756 Pro series as mobile rigs

[n3aws at aol.com]

As I approach retirement, I'm thinking about upgrading my mobile setup with the intention of improving performance primarily in state QSO parties.? I currently operate mobile with an Icom 706 MkIIG in a 23 foot motorhome using the marine deep cycle battery for power and a Hustler antenna.? I only operate while parked or when someone else is driving.? While the 706 is a reasonable mobile rig, I wonder if the improved receiver in my 756 Pro II would work well in the mobile environment.? I've only had the Pro II a short time and have only used it once in a contest (June 08 ARRL VHF).? I operate QRP 95% of the time and always in contests.? Also, I currently operate 95% SSB although when I retire I'll probably operate CW & digital modes more often.

So my questions are: how well does the 756 Pro series handle the noise of a mobile environment?? Would I experience enough of a RCVR improvement to make it worth the effort to upgrade the 706 to the Pro II?? Would the improved ergonomics of the larger 756 be reason enough to upgrade?? Any other input from anyone who has used a Pro series XCVR mobile would be appreciated!

Thanks and 73,
