Easiest is to connect a piece of wire to the antenna jack, then drag the other end along a grounded surface. A file is great if you have one, but just scratching along a piece of metal works. Switch the blanker on and off in SLOW AVC and you'll the see the average. Then on FAST AVC you hear and see the meter jump.
