[CQ-Contest] RBN high busted rate during WAE DX?

[Pedro Colla]

Thank you for all the answers received both on the reflector and privately.
@N4ZR: Thank you, good thoughts as usual. I'll check both possibilities at my station that went unnoticed to me during the contest and pay a further look at the data in order to understand if there is any pattern in the nodes producing the busted call. And yes, the busting pattern is as if the first dot of the L were missing changing into a D (LT7H->DT7H). I've to say that new failures aside this is a configuration and equipment I've been using for quite a time now and never experienced busted call % significantly above 5% or so. This was an order of magnitude above that and that is the reason to wonder about what can be causing that.
@VE9AA: If you read carefully I'm not presuming nothing wrong on the RBN, just reporting an issue and providing the data I can gather on it. I've reported malfunctions of the N4ZR before and cooperated with data to help fixing it. I believe RBN is one of our greatest assets and will do my best to help on fixing/improving it (assuming that is needed).
@OG6N: Surely checking my equipment is on the list, nobody reported me any problem with my signal during the contest either on the cluster system or on the air (as I got in other ocassions something went wrong), and beyond horrid CONDX I had been able to have reasonable rates when conditions opened. A bad signal would explain any sort of random busted call, not just a wrong first letter 100% of the time. This is not the first time something happens with the RBN and I believe that openly asking is a way to help. As said, I had no clue my signal were bad, no local indication on my station provide me clues about that and nobody over the air did told me nothing either. And, no, there is no correlation whatsoever with 95.5% confidence between run rate and busted rate, I did that analysis already.
