Hi July1baby- first off sorry about your fathers passing,i hope your doing ok it tough losing a family member.
anyway lets see if i can shed some light for you,first off i looked up your scanner and its a very old one,you can try and sell it and maybe someone will buy it because they dont make them kind anymore,i looked up your town and what frequencies they use in essex and area towns,it seems like no one uses trunking or digital system so that good for someone that has an anaolg scanner such as this one you have.
now you did say you were not familiar with police scanners,there could be a few reasons why your not picking anything up.When programming the frequncies are you entering the decimal point in there? when i first started scanning back in the day i did not know anything and i entered all the numbers ( I.E 154400) instead of using the decimal (I.E. 154.400if 0you did put the decimal point in then that should be ok.
second maybe there is an issue wtih the antennae,check to see if has a tight connection on the back of the unit.if it is then possibly something could be not working properly on the inside such as a burned out circuit board or a broken wire.or the antena connetion on the inside.
you said you moved the squelch back and fouth so thats not an issue-
and then third is maybe theres no action in your area lol seriously though i never had this exact scanner but i had enough of them to know what usually goes wrong,maybe someone else will post some info that i didnt think of and may also help,
and if you were to get into the hobby and wanted to but a scanner ,all you would need is a cheap anolg scanner if you are just monitoring your town and county,there is no need to spends a fortune on a trunking digital scanner.
i hope you fix your problem
