Hello Kamal! Thank you for the nice FT8 QSO today on 17M. After monitoring for you for several days, my friend K9EL notified me that you were decoding very well today and I am glad that we were able to complete a QSO. 14,400km is a very long distance between out QTH locations! Good job! Best 73 and wishes for good DX.

Hello Kamal! Thank you for the 17 meter FT8 QSO today. Conditions between 4S7 and central USA have been poor as we have been watching for you every day. But today you came through very well and I am happy to add you to my log in 2019. Best wishes to you and your family from the USA.

Hi Kamal! Thanks for a very successful QSO last night on 160m. It's amazing how well your magnetic loop antenna works. I look forward to have QSO's with you on other bands aswell. Have a look at our club website for LA2T in Trondheim (www.la2t.no) where I regularly post articles. 73 Havard, LB9RE
