[RFI] Baby Monitor Advice

[N6KJ]

I just found out this weekend that 100W on 6 meters really wreaks havoc
with our baby monitor.  I suspect that the baby monitor is a 49MHz model
with cruddy filtering.  I get RFI even when running the baby monitor on
batteries.  I need to find a new baby monitor.  Anyone know any that 
are known to be free of this problem (like maybe 2.4GHz models)?  Any
other advice as I shop for one?
