In other words, they were on a cellphone chat with the mother ship, surfing interweb dating sites, watching reruns of Mayberry RFD, or, perhaps, something more remarkable.

if not actual TX, it's prolly electronic noise coming from within...

it tells us:

1)signal strength and then the frequency(am/fm/uhf/vhf/...) can help determine the type of source: navigation/range finding/etc

2)captured frequency/(freq ranges) to be monitored from now on and what type of equipment to use for best reception

3)what freqs will it interrupt if/when more power is applied

4)by spectrum analysis we might be able to determine if is an actual TX, cyclical/mechanical or simple noise/leakage from the craft

and a couple more that i won't get into here

but you get the idea...
