YEAH! I did it!!!
I finally got my DXCC on 160 meters. The last entity to confirm was ZA1WW in Albania. Thankfully it was via LoTW so there was no need for a trip to the card checker.
How hard was it? Not as hard as you think, but no cakewalk either.
The key to 160m operating is listening. "If you can't hear 'em you can't work 'em" is especially true on this band. For this reason I have done extensive research on receiving antennas, noise floor and operating techniques to maximize SNR. I fought many pileups, including some rare (on topband, anyway) entities in far off places like Cote d'Ivoire, and Annobon Island.
Anyway, I enjoy this for now and bask in the glory of 9 band DXCC!!
