Find out how our bandpass filter worked at a POTA (Parks on the Air) activation on July 9th, 2024.
In the video, you will see the close proximity of antennas and transmitters used with our 20M bandpass filter that KD9QXL used and made the most contacts during the day with. His son used my callsign W9PIO on 10M with our 10M bandpass filter while I monitored and took a video of our POTA activation. 10M was slow, but 20M received a lot of contacts.
No RF interference happened to either operator while transmitting on either the 857D or 991A. Antennas where no more than one car length apart.
