I have a Claude (Pro) account and have recently been getting to know him and his capabilities. I can tell he’s craving a big code project, but until then, I’ve been annoying him with rather plebeian tasks. Fortunately, he’s not easily offended and has entertained me with his wit and brains.

Last night I selected all my ham radio log entries made so far this year (just over three months of data) and exported that as an ADI file. I then asked Claude to examine that file and tell me how many unique DXCC entities it included. Here was our conversation with his replies:

ME: “scan the ADIF file /iCloud Drive/Desktop/test1.adi and report on how many unique countries were worked”

CLAUDE: 87 unique DXCC entities worked, based on the DXCC field (the most reliable identifier). The COUNTRY field lists 93 unique name strings, but that includes some duplicates from inconsistent naming:

  • "Canary Is." and "Canary Islands"
  • "Cayman Is." and "Cayman Islands"
  • "Galapagos Is." and "Galapagos Islands"
  • "USA" and "United States"

Notable highlights from the log:

  • Europe is well represented: England, Scotland, Wales, Northern Ireland, France, Germany, Italy, Spain, Portugal, Switzerland, etc.
  • Caribbean has strong coverage: Cuba, Puerto Rico, Virgin Islands, Bonaire, Curacao, Martinique, Aruba, Barbados, Grenada, Dominica, Haiti, etc.
  • South/Central America: Brazil, Argentina, Venezuela, Colombia, Peru, Ecuador, Uruguay, Chile, Panama, Costa Rica, El Salvador, Suriname, French Guiana

Rare/interesting ones: Desecheo Island, Sable Island, Saint Helena, Guinea-Bissau, Aland Islands, Austral Islands

That took all of 43 seconds for Claude to scan the file, figure out ADIF and learn all about DXCC to make a few salient points about which entities are rare, etc.*

Impressed, I asked a follow-up question:

###

ME: “how many of those contacts were confirmed?”

CLAUDE: 67 of the 87 DXCC entities are confirmed via LoTW — leaving 20 still unconfirmed.

ME: “Thanks!”

CLAUDE: You’re welcome! Good luck chasing those 20 unconfirmed entities — hopefully some of them will show up on LoTW soon. 73!

I’m not sure how Claude was able to learn ham radio lingo so quickly, but he’s a curious little fellow to have in the shack!
