Information on how to contact these gentlemen is on the ARRL card checker web page. To access the contact information, use this CARD CHECKER LINK. This database includes their phone numbers, email, and home addresses.
All card checkers can check DELETED COUNTRIES, but only those who themselves have a 160 meter DXCC can check other’s 160 meter cards (none at this time in this area). All these checkers can check DXCC, WAS, WAC, and VUCC cards.
There is a new method of submitting DXCC cards to the ARRL checkers.
Rather than downloading the form and filling it out manually (with a pen), you go to the ARRL website and access the form on your computer and fill in the details there. Your entry, if not finished, is saved on the ARRL computer servers for additional entries until you are finished. I have an unfinished entry now and add cards to the list as they come in the mail. When you are finished entering and ready to submit to a checker, you fill out the rest of the form (name, address, method of payment, etc.) and print it. That finished form, the QSL cards, and the SASE (addressed to ARRL in Newington, CT) are brought to the checker. Here is a QSL CARD LINK to the new information.
