I live in Northern California, 30 miles NE of Sacramento. No matter what time of the day, I do not see any stations on the Band Activity side with 7 in their call sign on 17m. Any suggestions as to how I might tweak my settings or Antenna to at least see them? I am using an EFHW 80-10 wire but only about 5 feet high, due to restrictions. Receiver is ICOM 7300. thanks for any ideas.
