I do not accept that IP3 figures on their own are very meaningful. It doesn't matter how good the IP3 figure is, if the phase noise is not commensurate, it is, to put it crudely, as much use as teats on a bull!

I agree and  thats the point I suppose about the whole marketing hype behind  IP3 figures. Equally bad is ignoring IMD  and phase noise performance on TX.  If bad transmitters block  your ability  from realizing  your receivers potential, what point is it owning the best receiver when its potential will never be realized. On VHF good transmitter design is just as important as a good receiver. All current all mode VHF/UHF transceivers from Japan dont have transmitters that meet the needs of serious contesters   especially in Europe.  Icoms intercept point figures   have no meaning in the real contest world.

When there is a true high performance VHF/UHF transceiver released from Icom, I will buy and so will many more VHF contesters.
I am sick and tired of the endless commercial hype and new models that offer no performance  improvement. At least in the HF market some manufacturers are delivering performance.
