Not to be one of "those" guys, but 452.000 MHz is outside of the ham radio 70cm band, and the Yaesu VX-3R is FCC type accepted only for use within the amateur radio bands.
Just sayin'
According to the Yaesu website, the VX-3R does the following tuning steps:
5/9/8.33/10/12.5/15/20/25/50/100 kHz
The website does not say if it transmits in NFM.
