Hi

The most basic question is - what do you have already? My first adventure with 
line monitoring was with a vacuum tube based counter. It was what I just happened 
to have. 

One basic need is something to monitor against. GPS is a pretty cheap option if you
have nothing already. 

Rather than guessing from there …
