3cRadio

greetings all! new to gmrs radio and had a repeater question. anyone now how its possible for my base station (20w) radio to make contact (receive & transmit) to a repeater that's over 75 miles away? i'm using a amazon special gmrs fiberglass antenna that's only mounted 10 ft off the ground. i have a local repeater approx. 6 miles away that uses .575 frequency with a tone of 162.2 in and out. i can't connect with it due to a mountain in between it and my location. as stated, the other evening i was able to communicate with the repeater that's further away which does have a .575 frequency with a tone of 162.2 in but 198.8 out. i'm not sure how this is possible; am i some how connecting to the repeater local to me and it relaying he signal to the further repeater even though it has a different output tone?

i too recently (April) purchased an H8 Gen 2 GMRS version that i am running unlocked. i attached a surecom meter and did notice that on the GMRS frequencies, the power still doesn't go above 5 watts.
