A QSO with a heart of Africa

Last few days I`ve been watching for 9Q/DKSMO Otto operating from Democratic Republic of Congo. Great tools to watch any DX by call-sign is a widget from DXWATCH.COM , here is my widget for Otto:

I was waiting for Otto on 17m today, I had my radio on 18.069 .... when he appeared on 15m. Wasn`t busy at all. He was working few DL stations and I gave him a call. New one DXCC in my HF collection! On 21Mhz his favorite freq is 21.010 +/- / On 17m 18.069Mhz this is old school of DXing, be on the frequency before pile-up gets heavy ;)
