I discovered my rx antennas worked much better if my tx antenna was completely disconnected from the station. Most coaxial relays or T/R switches only break the center conductor. That's not good enough. There has to be a complete disconnection which I provided by using an open frame relay mounted in a plastic box. On 160 m. such a device will not present an impedance bump but this solution worked for me because I don't care about QSK. This may not be necessary if the tx and rx antennas can be separated by one or more wavelengths. 73 Rob K5UJ _________________ Topband Reflector Archives - http://www.contesting.com/_topband |
