tuning is totally blown away.

Oh my, anonymous poster, you compare a frequency deviation of 
2.5% at VHF (135 - 139 MHz)   with a frequency change of 
250kHz at (say) 3 MHz       But wait: that's a 8.3% change. 
 
And you say that the effect of a 250kHz difference at HF is much 
greater than 4 MHz at VHF? 
 
Well yes! 8.3% is much greater than 2.5% 
 
How long did you say you have been doing this sort of thing?
