Another historic milestone has been reached today in the shack of EI2KC. I've just received confirmation of my 100th DXCC confirmed on 80 metres on ARRL's Logbook of the World. That makes my eighth band on which I have received 100 or more confirmations. I am now entitled (when I get the money together!) to apply for 11 certificates - DXCC Mixed, DXCC Phone, DXCC CW, DXCC 80m, DXCC 40m, DXCC 30m, DXCC 20m, DXCC 17m, DXCC 15m, DXCC 12m and DXCC 10m.
My confirmations on 80m had been at 89 for months. So I decided I would participate in the CQWW CW contest in November on 80 metres only. This helped push my confirmations up to 98 and then I also received an LoTW confirmation from the 5T0SP Mauritania dxpedition. The 100th confirmation was from PJ5J Saba & St. Eustatius.
I suppose in the meantime I should hit the airwaves on digital modes and try to get to the 100 on that band...
All of the above has been achieved in less than three years. I only use EI2KC QSOs on LoTW and I got that callsign in March of 2010.
