3cRadio

thanks for the reply! pretty amazing that a 5w radio can make it up that far. since earth has the whole coverture thing and obstructions, i can see why it might not go as far. from what i can gather, the tower is probably approx. 2k ft elevation and i'm at 100 ft. that image is pretty cool. cant seem to find the site you were using but here's my google map image. there are some hills but no huge mountains (from what i can tell).

thanks for the reply! there isn't a mountain as high as the closer repeater but i'm located in norcal (suburbs) and there are hills, trees and several buildings towards the further repeater; no real line of sight, open fields or deserts. if i'm correct in thinking who you are; love your vids!

thanks for the reply! never hear of tropospheric ducting but after looking it up, it's very possible. supposedly in area Aug & Sept have a higher probably of this happening. i'm not familiar with the linking of repeaters but from my understanding this is considered illegal with gmrs repeater but the repeater is operated by a radio network that has a few repeater near each other; maybe they are linked somehow. my radio tones are set to 162.2 in and out, so no sure how i could hear them on the receive side; that still puzzles me. thanks again for the reply!

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.
