Lee, Very well said. So many look at the duplexer as allowing a tx and rx on same feedline, but a good one also provides for some front end and tx noise filtering. I think the repeaters from ICOM, Kenwood, Yeasu and other DC to light programmable repeaters rely on this filtering.
I do like and use the mobile duplexers, but one needs to know what they provide and what they do not. 73, ron, n9ee/r Ron Wright, N9EE 727-376-6575 MICRO COMPUTER CONCEPTS Owner 146.64 repeater Tampa Bay, FL No tone, all are welcome.
