I was wondering when I hear skip on my scanner (VHF low and high) on the freqs that my city police or fire department use, do they hear the skip too? Since i'm hearing it, wouldn't they?

If you have programmed in the pl or dpl in your scanner than yes

Ah, okay. Thanks for the reply.
What does programming PL or DPL in his scanner have to do with whether or not the police hear it?
Now the correct answer; the only way they can hear "foreign" transmissions is if they by sheer coincidence use the same PL or DPL. The odds against are nearly astronomical considering all possible PL tones and DPL codes so a safe answer is no, they don't hear them.

Not so astroniomical....My Local FD repearter when the condtions were right would get a fire repeater 2 states over with the same PL and output as the input and PL as ours..

Because if the frequency he's listening to has some skip come in and his radio has the pl or dpl associated with that freq then probably other people on the system might be hearing it

Most of the skip I hear comes over my Uniden BC350C, with that scanner, too listen to select freqs (and what I do) all what you do is choose a freq from a pre-programed freq bands and program it into the private bank. There is no PL or DPL codes shown, so am guessing it does it automatically? Or maybe it doesn't do those codes and it receives everyone who uses that certain freq?
Correct It does not do DPl/PL so it will receive everyone that freq.

Back in the late 80's and 90's my Uncle worked for the Sterling Hgts Police here in Michigan at that time they used 460.475 .Lucas County Oh used the same freq he said they could hear them on there radios when the skip was in swing
Low band skip
with the trend over the last twenty years to leave low band, Ohio State Patrol used to get a lot of low band skip. Are there any low band channels being used anymore that skip could be listened to? My girlfriend has never listened to a radio trans. hundreds of miles away and it would be neat to listen to it again.
and back before PL was used auglaize county would kick Springfield Fire repeater all day as well as a Ft wayne signal kicking the repeater. It was fun to listen to but annoying. Lexington fire EC 3 to fire control,would roll into SFD on 154.37 as well as Newark fire other side of Columbus. allegedly base to base once had comm.
anybody listening to any low band skip in Ohio since this is supposed to be sunspot year??

You're assuming that skip is depedent on the sunspots - that's not entirely true. Skip on VHF frequencies and higher can be greatly influenced by local weather conditions as well (and is much more common than solar-enhanced skip).
There's also a mechanism that is not completely understood where signals can be reflected by highly ionized clouds in the E layer of the ionosphere. Referred to as E-Skip (and often written as Es) such skip doesn't usually last very long (as opposed to F skip, which can last for long periods).
You might want to read up on weather enhanced skip on Bill Hepburn's excellent website - it's somewhat basic in nature, but it's great as a primer...
