baofengs have shit receivers in them. if I am on 440 with mine and a APD officer keys up somewhat close to me I can hear them (they use a 453 rpt out/458 in) if i get close to the apd tower I can hear it all.
so hearing a fd call from a station 2 miles away on vhf with a baocrap isnt "skip" its intermod due to crappy radio.
2m "skip" would be hearing a repeater on 147.22 from a couple hundred miles away.
