Sounds about right! I used to run pileups out of Hong Kong at crazie speeds back in the mid 90s, but the other ops figured it out... If there were a lot of stations, the speed would thin things out a bit if there were too many stations calling.
Congratulations, that is some great Morse Runner-ing. I could get about half of the callsigns, the slower ones. How does he change the pitch of the "caller" he is receiving? TU es 73 de VE3YT
