Yuri, Thanks for your input. Tom asks, where are the other stations? It is a one pony race. Well I am sure if we look at the CQ logs for that year we will see that there were other Carib stations on

Juan, Am I wrong to assume that skimmers are not calibrated? They should be calibrated to S-9=50 uV into 50 ohms at least to provide some kind of uniformity band-to-band and skimmer-to-kimmer. I don'
