New to Ham Radio. Have an ICOM 7300 and a 102' G5RV. Antenna center is up in a tree about 40' with the legs in an inverted V down to about 10' each. On 20 and 17 I can clearly hear transmissions from Europe, South America, etc., but no one seems to hear me! I've done some FT8 with mixed success. QSO's as far as France. One thing I've noticed is that incoming signal reports are often +13db while the ones I'm getting back are down at -11db or sometimes lower. I'm going to try and get the antenna legs higher, but wondering if that will help.
