KQ4TYT- HOA Ham Radio Guy on Instagram: "So I was able to repeat the ability to hear a repeater 90 miles away. The question now, is it caused by tropospheric ducting or is this the normal? Well so far both times have been at night while the air is cooling under nearly identical weather conditions. To determine the answer I’ll have to try it one more time but during the day when it’s warmer to see if it’s just good timing using the ducting or if it’s normal. I have a good feeling it’s ducting. #a
