In the morning a second transmitter on 1296 kHz is on air using a 2 x 3 element vertical array. At 190 km distance they produce both a -15 dBm signal, which I use for off air IMD tests of active antennas. The tramsmitters are phase locked as with a poor IMD device I can listen to both stations at 1944 kHz. It sounds like they are talking at the same time, but no beatnote whatsoever. 73, Roelof bakker, pa0rdt
