Working on a RasPi based antenna switcher to compare 2 different antennas by switching between them at know intervals - data is then sorted out to compared the 2 antennas as close as possible in their timeslot.

Then I just noticed a ham that's posted a video and forum msg (not here) last week, running 2x WSPRlite simultaneously, and to differentiate the units and antennas, he appends a '1' to his call area - for example, K4BD and K41BD - I'm wondering if this isn't considered bogus callsign usage? Does WSPRnet (or DXplorer) scrub one of them?
