If you do a full freq look at the Kiwi WF you can often see the chirp sweep go by. I'd like to be able to pick a chirp TX site by name name, Millstone Hill for example, and knowing it's start time, be abe to ID that sweep that goes by. The highest freq seen would indicate the MUF for it at the Kiwi RX site. -
