Skinnerfam95 Posted December 12, 2021 Report Share Posted December 12, 2021 Hi, I purchased the RT97S from myGMRS.com. I'm having issues as follows. My repeater settings: - Using the 650 frequency pair - ENC/DEC CTCSS codes to OFF on the repeater - SQL is set to 1 - Transit function is ON - W/N is set to WIDE (matches the radios) - TX Power is set to HIGH The repeater antenna is 20FT high, a gain of 7dB, and SWR of 1.3/1.8 respective to the frequency pair. I'm using Radioddity GM-30 (5W) radios. For a simplex baseline using two GM-30 radios: - At 3 miles apart I get crystal clear both ways - One radio is using the repeater antenna - The other radio is using a mobile mag mount roof antenna When using the repeater with the transmitting radio is line of sight less than 500 feet from the repeater everything seems to work ok. -- I've received clear transmissions from a receiving radio as much as 8 miles away line of sight away from the repeater so long as the transmitting radio is less than 500 feet from the repeater. I am having limited success transmitting at 1000 feet away line of sight. - Radios that are less than 500 feet from the repeater hear the transmission of the radio that is 1000 feet away clearly - Other radios at 1000 feet from the repeater hear the transmission broken - The tail tone (burst of white noise) comes through strong on all radios - It appears to me that the transmission is degraded only when repeating the transmission of a radio 1000 feet or more away. The tail tone is after the transmission has completed and comes through strong Transmitting radios over 1000 feet from the repeater have worse symptoms than described above. It is unusable. Please help. Thanks, Matt Quote Link to comment Share on other sites More sharing options...
