I just picked up a BK Precision 1856B frequency counter for my shack. It has been a few years (around 30) since I had one. What is the easiest way to set it up for checking frequency on the various radios? Would it be better to pick up a RF sampling port or home brew one? Would it just be as easy to use the antenna that came with the counter (it picks up my Wifi)? As I said it has been years and what I find online is a ton of differing opinions and ways.
