Dick and all, It sounds like you had some RF in that headphone splitter/amplifier.
I am coming to believe that each Field Day setup should include a 1/4 wavelength of wire for each band of operation (to serve as a counterpoise wire) and enough braid or other strapping material to connect all enclosures together - connect the counterpoise wires to the ground strapping. Field Day is often run with random antennas, end fed antennas, offset fed antennas, and all those are prone to RF-in-the-shack problems - the energy from another station in a Field Day multi setup can only make the situation more complex. A few wires can help to tame things down and reduce the number of "strange happenings". The counterpoise wires are a quick and easy method to bring the RF impedance at the radio location down to a good simulated RF ground level. Maybe it is a good idea to mark this down in your notebook of 'things to do next Field Day'. 73, Don W3FPR Dick Dievendorff wrote: > I used a Behringer HA-400 briefly for our FD effort and quickly replaced it > with a standard 2 phone jacks to 1 phone plug rigid adapter.
