Are you sure about the automated "robot" activity on the JT modes? Only asking because I think that I've seen evidence of this myself in what little FT8 I've done recently. There is really no other reason why a station tries to work me more than once, sometimes even calling me more than once in a single session of operating. right? It's really annoying, so I just am asking how do I know that it's a bot or not? I usually do not answer a repeat caller anyway, but it does get annoying, especially when they are calling me repeatedly, usually when I was trying to work DX or something... So, what's the best way to winnow out the automated stations versus the stations that actually have a real person sitting at the controls? I'd really like to know... It's probably just something we have to put up with, right?
