In this episode we meet Daniel Winn, WV1T, a very active portable ham radio opertor.  Daniel was searching for a way to filter out strong local signals when operating in the field and he started building stub tuned filters with coaxial cable.  This simple and cost effective approach is a great way to build notch filters that can significantly reduce unwanted interference from transmitters operating at the same location but in other HF bands.  This is a great technique for Field Day and similar activities.  Daniel holds an extra class amateur radio license and is a professional electrician.
