The answer's pretty clear. Many of you are QRPers interested in new gear. My thoughts on the IC705 got almost twice the viewership of any other item.
Antennas feature prominently because for a while that was the only topic covered here. Those for small spaces are very popular. For example apartment HF antennas and magnetic loops. Maybe it's because you're more likely to be on the web than on the air if your antennas are limited?
There's also a fair interest in VHF/UHF antennas. Three of the top 10 posts are in this category.
Anyway you can see all the top 10 below. It will help me think of things to write about.
